We look at the division of 88718929 by 641 
We want to divide 88718929 by 641.

Advancing to step 1:
The number 641 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 641

Advancing to step 2:
88 divided by 641 is 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 641

Advancing to step 3:
887 divided by 641 is 1 with a remainder of 246.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 641 from 887 to get 246.
Bring next digit (1) of the dividend behind the 246 and repeat the process: 2461 / 641

Let's proceed to step 4:
If we divide 2461 by 641, we get 3 and a remainder of 538.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 538 after subtracting 1923 from 2461.
Take the next digit (8) from the dividend and append it to 538, then repeat: 5388 / 641

Let's proceed to step 5:
5388 divided by 641 is 8 with a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtract 5128 from 5388 to get 260.
Fetch the next digit (9) from the dividend, attach it to 260 and continue: 2609 / 641

Let's proceed to step 6:
If we divide 2609 by 641, we get 4 and a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 1384.0
Subtract 2564 from 2609 to get 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 641

On to step 7:
452 divided by 641 is 0 with a remainder of 452.
Use 0 as the next digit of our solution. 
Result so far: 13840.0
If we take 0 away from 452, we end up with 452.
Include the next digit (9) from the dividend after 452, then repeat: 4529 / 641

Advancing to step 8:
641 goes into 4529 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 138407.0
Subtracting 4487 from 4529 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
When dividing 420 by 641, we get 0 with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 138407.0
If we subtract 0 from 420, we 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.

Going ahead to step 10:
641 can be fit into 4200 6 times, resulting in a remainder of 354.
The number 6 becomes the next digit in our result. 
Result so far: 138407.06
Subtracting 3846 from 4200 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 11:
The number 641 fits into 3540 5 times, leaving a remainder of 335.
The next digit of our result is 5. 
Result so far: 138407.065
If we subtract 3205 from 3540, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 12:
641 can be fit into 3350 5 times, resulting in a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 138407.0655
Subtract 3205 from 3350 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 138407.0655, with a leftover of 0.00145.
