Let's divide 74830521 by 780
We want to figure out the number of times 74830521 can be divided by 780.

Step 1:
When dividing 7 by 780, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 780

Going ahead to step 2:
The number 780 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 780

Moving on to step 3:
748 divided by 780 is 0 with a remainder of 748.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 748 leaves us with 748.
Grab the next digit (3) from the dividend, add it to 748, then carry on: 7483 / 780

Advancing to step 4:
780 can be fit into 7483 9 times, resulting in a remainder of 463.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 463 after subtracting 7020 from 7483.
Take the next digit (0) from the dividend and append it to 463, then repeat: 4630 / 780

Moving on to step 5:
4630 divided by 780 is 5 with a remainder of 730.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtracting 3900 from 4630 leaves us with 730.
Append the next digit (5) from the dividend to 730 and continue with: 7305 / 780

Going ahead to step 6:
7305 divided by 780 is 9 with a remainder of 285.
Put 9 as the next digit of the answer. 
Result so far: 959.0
Subtracting 7020 from 7305 leaves us with 285.
Take the next digit (2) from the dividend and append it to 285, then repeat: 2852 / 780

Moving on to step 7:
If we divide 2852 by 780, we get 3 and a remainder of 512.
The number 3 becomes the next digit in our result. 
Result so far: 9593.0
Subtracting 2340 from 2852 leaves us with 512.
Include the next digit (1) from the dividend after 512, then repeat: 5121 / 780

Let's proceed to step 8:
780 can be fit into 5121 6 times, resulting in a remainder of 441.
The number 6 becomes the next digit in our result. 
Result so far: 95936.0
If we take 4680 away from 5121, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 9:
4410 divided by 780 is 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 95936.5
The remainder is 510 after subtracting 3900 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
780 goes into 5100 6 times with a remainder of 420.
Record the quotient 6 as the next digit in the result. 
Result so far: 95936.56
Deduct 4680 from 5100 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
780 goes into 4200 5 times with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 95936.565
Subtracting 3900 from 4200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
If we divide 3000 by 780, we get 3 and a remainder of 660.
The number 3 becomes the next digit in our result. 
Result so far: 95936.5653
If we subtract 2340 from 3000, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 13:
The number 780 fits into 6600 8 times, leaving a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 95936.56538
Deduct 6240 from 6600 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
The number 780 fits into 3600 4 times, leaving a remainder of 480.
The next digit of our result is 4. 
Result so far: 95936.565384
If we take 3120 away from 3600, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 15:
When dividing 4800 by 780, we get 6 with a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 95936.5653846
Subtracting 4680 from 4800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
When dividing 1200 by 780, we get 1 with a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 95936.56538461
Subtract 780 from 1200 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 95936.56538461, and the remainder is 4.2e-07.
