We look at the division of 86856647 by 641 
We want to figure out the number of times 86856647 can be divided by 641.

Going ahead to step 1:
641 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 641

Going ahead to step 2:
86 divided by 641 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 641

On to step 3:
641 goes into 868 1 times with a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 641 from 868 leaves us with 227.
Fetch the next digit (5) from the dividend, attach it to 227 and continue: 2275 / 641

Going ahead to step 4:
2275 divided by 641 is 3 with a remainder of 352.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1923 from 2275, we get 352.
Grab the next digit (6) from the dividend, add it to 352, then carry on: 3526 / 641

On to step 5:
The number 641 fits into 3526 5 times, leaving a remainder of 321.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 3205 from 3526 and we're left with 321.
Append the next digit (6) from the dividend to 321 and continue with: 3216 / 641

Advancing to step 6:
641 can be fit into 3216 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 1355.0
Subtracting 3205 from 3216 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 641

Going ahead to step 7:
When dividing 114 by 641, we get 0 with a remainder of 114.
Record the quotient 0 as the next digit in the result. 
Result so far: 13550.0
Deduct 0 from 114 and we're left with 114.
Bring next digit (7) of the dividend behind the 114 and repeat the process: 1147 / 641

On to step 8:
641 goes into 1147 1 times with a remainder of 506.
The number 1 becomes the next digit in our result. 
Result so far: 135501.0
Subtracting 641 from 1147 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 9:
5060 divided by 641 is 7 with a remainder of 573.
Put 7 as the next digit of the answer. 
Result so far: 135501.7
The remainder is 573 after subtracting 4487 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Going ahead to step 10:
The number 641 fits into 5730 8 times, leaving a remainder of 602.
Put 8 as the next digit of the answer. 
Result so far: 135501.78
Deduct 5128 from 5730 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 11:
641 goes into 6020 9 times with a remainder of 251.
The next digit of our result is 9. 
Result so far: 135501.789
Subtracting 5769 from 6020 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 12:
The number 641 fits into 2510 3 times, leaving a remainder of 587.
Record the quotient 3 as the next digit in the result. 
Result so far: 135501.7893
Subtracting 1923 from 2510 leaves us with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 13:
641 goes into 5870 9 times with a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 135501.78939
Subtract 5769 from 5870 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 14:
641 can be fit into 1010 1 times, resulting in a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 135501.789391
The remainder is 369 after subtracting 641 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 15:
641 goes into 3690 5 times with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 135501.7893915
If we take 3205 away from 3690, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 16:
4850 divided by 641 is 7 with a remainder of 363.
The number 7 becomes the next digit in our result. 
Result so far: 135501.78939157
Subtract 4487 from 4850 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Our division results in 135501.78939157 with a remaining 3.63e-07.
