Let's divide 70306072 by 780
Let's see how many times 780 fits into 70306072.

Advancing to step 1:
If we divide 7 by 780, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 780

Let's proceed to step 2:
When dividing 70 by 780, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 780

Advancing to step 3:
780 can be fit into 703 0 times, resulting in a remainder of 703.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 703, we get 703.
Include the next digit (0) from the dividend after 703, then repeat: 7030 / 780

Advancing to step 4:
7030 divided by 780 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7020 from 7030 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 780

Advancing to step 5:
The number 780 fits into 106 0 times, leaving a remainder of 106.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 106 to get 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 780

Step 6:
780 goes into 1060 1 times with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 901.0
The remainder is 280 after subtracting 780 from 1060.
Include the next digit (7) from the dividend after 280, then repeat: 2807 / 780

Advancing to step 7:
If we divide 2807 by 780, we get 3 and a remainder of 467.
The next digit of our result is 3. 
Result so far: 9013.0
Subtract 2340 from 2807 to get 467.
Take the next digit (2) from the dividend and append it to 467, then repeat: 4672 / 780

On to step 8:
780 can be fit into 4672 5 times, resulting in a remainder of 772.
The next digit of our result is 5. 
Result so far: 90135.0
The remainder is 772 after subtracting 3900 from 4672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 9:
If we divide 7720 by 780, we get 9 and a remainder of 700.
Put 9 as the next digit of the answer. 
Result so far: 90135.9
If we take 7020 away from 7720, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 10:
If we divide 7000 by 780, we get 8 and a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 90135.98
Deduct 6240 from 7000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 11:
If we divide 7600 by 780, we get 9 and a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 90135.989
Deduct 7020 from 7600 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 12:
When dividing 5800 by 780, we get 7 with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 90135.9897
Subtract 5460 from 5800 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
3400 divided by 780 is 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 90135.98974
If we take 3120 away from 3400, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
780 can be fit into 2800 3 times, resulting in a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 90135.989743
If we subtract 2340 from 2800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 15:
When dividing 4600 by 780, we get 5 with a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 90135.9897435
Subtracting 3900 from 4600 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 16:
If we divide 7000 by 780, we get 8 and a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 90135.98974358
Deduct 6240 from 7000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

In conclusion, the division gives 90135.98974358 with a balance of 7.6e-07.
