We're dividing 77441872 by 781 
We want to figure out the number of times 77441872 can be divided by 781.

Moving on to step 1:
781 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 781

Going ahead to step 2:
When dividing 77 by 781, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 781

Advancing to step 3:
774 divided by 781 is 0 with a remainder of 774.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 774, we end up with 774.
Grab the next digit (4) from the dividend, add it to 774, then carry on: 7744 / 781

Going ahead to step 4:
When dividing 7744 by 781, we get 9 with a remainder of 715.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7029 from 7744 to get 715.
Fetch the next digit (1) from the dividend, attach it to 715 and continue: 7151 / 781

Step 5:
The number 781 fits into 7151 9 times, leaving a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 7029 away from 7151, we end up with 122.
Include the next digit (8) from the dividend after 122, then repeat: 1228 / 781

On to step 6:
If we divide 1228 by 781, we get 1 and a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 991.0
Subtracting 781 from 1228 leaves us with 447.
Grab the next digit (7) from the dividend, add it to 447, then carry on: 4477 / 781

On to step 7:
If we divide 4477 by 781, we get 5 and a remainder of 572.
Record the quotient 5 as the next digit in the result. 
Result so far: 9915.0
Subtract 3905 from 4477 to get 572.
Append the next digit (2) from the dividend to 572 and continue with: 5722 / 781

Advancing to step 8:
781 goes into 5722 7 times with a remainder of 255.
The next digit of our result is 7. 
Result so far: 99157.0
Subtract 5467 from 5722 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
The number 781 fits into 2550 3 times, leaving a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 99157.3
If we subtract 2343 from 2550, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 10:
781 goes into 2070 2 times with a remainder of 508.
Record the quotient 2 as the next digit in the result. 
Result so far: 99157.32
The remainder is 508 after subtracting 1562 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 11:
5080 divided by 781 is 6 with a remainder of 394.
Record the quotient 6 as the next digit in the result. 
Result so far: 99157.326
Subtracting 4686 from 5080 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 12:
781 can be fit into 3940 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 99157.3265
If we take 3905 away from 3940, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
781 goes into 350 0 times with a remainder of 350.
The next digit of our result is 0. 
Result so far: 99157.3265
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
781 goes into 3500 4 times with a remainder of 376.
The next digit of our result is 4. 
Result so far: 99157.326504
If we take 3124 away from 3500, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 15:
When dividing 3760 by 781, we get 4 with a remainder of 636.
Record the quotient 4 as the next digit in the result. 
Result so far: 99157.3265044
If we subtract 3124 from 3760, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 99157.3265044, with a leftover of 6.36e-06.
