Let's divide 77899252 by 641
Our goal is to divide 77899252 by 641.

Moving on to step 1:
When dividing 7 by 641, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 641

Let's proceed to step 2:
The number 641 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 641

Moving on to step 3:
641 goes into 778 1 times with a remainder of 137.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 641 from 778 leaves us with 137.
Grab the next digit (9) from the dividend, add it to 137, then carry on: 1379 / 641

Going ahead to step 4:
641 goes into 1379 2 times with a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1282 from 1379 leaves us with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 641

Advancing to step 5:
641 goes into 979 1 times with a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we subtract 641 from 979, we get 338.
Append the next digit (2) from the dividend to 338 and continue with: 3382 / 641

On to step 6:
3382 divided by 641 is 5 with a remainder of 177.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
Subtract 3205 from 3382 to get 177.
Fetch the next digit (5) from the dividend, attach it to 177 and continue: 1775 / 641

Advancing to step 7:
641 goes into 1775 2 times with a remainder of 493.
The next digit of our result is 2. 
Result so far: 12152.0
If we take 1282 away from 1775, we end up with 493.
Append the next digit (2) from the dividend to 493 and continue with: 4932 / 641

Going ahead to step 8:
641 goes into 4932 7 times with a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 121527.0
Subtracting 4487 from 4932 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 9:
4450 divided by 641 is 6 with a remainder of 604.
Use 6 as the next digit of our solution. 
Result so far: 121527.6
The remainder is 604 after subtracting 3846 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 10:
If we divide 6040 by 641, we get 9 and a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 121527.69
The remainder is 271 after subtracting 5769 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 11:
2710 divided by 641 is 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 121527.694
If we subtract 2564 from 2710, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 12:
The number 641 fits into 1460 2 times, leaving a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 121527.6942
Subtracting 1282 from 1460 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 13:
1780 divided by 641 is 2 with a remainder of 498.
Put 2 as the next digit of the answer. 
Result so far: 121527.69422
If we subtract 1282 from 1780, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

In conclusion, the division gives 121527.69422 with a balance of 0.000498.
