Let's divide 78861559 by 628
We want to divide 78861559 by 628.

On to step 1:
628 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 628

Going ahead to step 2:
If we divide 78 by 628, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 628

Step 3:
If we divide 788 by 628, we get 1 and a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 628 from 788 and we're left with 160.
Take the next digit (6) from the dividend and append it to 160, then repeat: 1606 / 628

Step 4:
628 goes into 1606 2 times with a remainder of 350.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1256 from 1606 leaves us with 350.
Include the next digit (1) from the dividend after 350, then repeat: 3501 / 628

Moving on to step 5:
3501 divided by 628 is 5 with a remainder of 361.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 3140 from 3501 and we're left with 361.
Include the next digit (5) from the dividend after 361, then repeat: 3615 / 628

Advancing to step 6:
628 goes into 3615 5 times with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we take 3140 away from 3615, we end up with 475.
Include the next digit (5) from the dividend after 475, then repeat: 4755 / 628

Step 7:
4755 divided by 628 is 7 with a remainder of 359.
Write down 7 as next digit of the result. 
Result so far: 12557.0
If we take 4396 away from 4755, we end up with 359.
Grab the next digit (9) from the dividend, add it to 359, then carry on: 3599 / 628

Moving on to step 8:
628 can be fit into 3599 5 times, resulting in a remainder of 459.
The next digit of our result is 5. 
Result so far: 125575.0
Deduct 3140 from 3599 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 9:
When dividing 4590 by 628, we get 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 125575.7
Subtracting 4396 from 4590 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
When dividing 1940 by 628, we get 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 125575.73
If we subtract 1884 from 1940, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
628 can be fit into 560 0 times, resulting in a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 125575.73
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 12:
628 goes into 5600 8 times with a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 125575.7308
Subtract 5024 from 5600 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 13:
The number 628 fits into 5760 9 times, leaving a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 125575.73089
Subtract 5652 from 5760 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 14:
If we divide 1080 by 628, we get 1 and a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 125575.730891
The remainder is 452 after subtracting 628 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 15:
628 goes into 4520 7 times with a remainder of 124.
Write down 7 as next digit of the result. 
Result so far: 125575.7308917
Subtracting 4396 from 4520 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 16:
628 can be fit into 1240 1 times, resulting in a remainder of 612.
The number 1 becomes the next digit in our result. 
Result so far: 125575.73089171
Deduct 628 from 1240 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The quotient of the division is 125575.73089171, and the remainder is 6.12e-07.
