31339758 ÷ 641 
We want to figure out the number of times 31339758 can be divided by 641.

Advancing to step 1:
641 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 641

On to step 2:
31 divided by 641 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 641

Let's proceed to step 3:
313 divided by 641 is 0 with a remainder of 313.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 313 leaves us with 313.
Fetch the next digit (3) from the dividend, attach it to 313 and continue: 3133 / 641

Going ahead to step 4:
3133 divided by 641 is 4 with a remainder of 569.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2564 from 3133, we get 569.
Bring next digit (9) of the dividend behind the 569 and repeat the process: 5699 / 641

Advancing to step 5:
5699 divided by 641 is 8 with a remainder of 571.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 5128 from 5699 and we're left with 571.
Include the next digit (7) from the dividend after 571, then repeat: 5717 / 641

Step 6:
The number 641 fits into 5717 8 times, leaving a remainder of 589.
Write down 8 as next digit of the result. 
Result so far: 488.0
If we take 5128 away from 5717, we end up with 589.
Bring next digit (5) of the dividend behind the 589 and repeat the process: 5895 / 641

Advancing to step 7:
641 goes into 5895 9 times with a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 4889.0
Subtract 5769 from 5895 to get 126.
Grab the next digit (8) from the dividend, add it to 126, then carry on: 1268 / 641

Let's proceed to step 8:
When dividing 1268 by 641, we get 1 with a remainder of 627.
Use 1 as the next digit of our solution. 
Result so far: 48891.0
Deduct 641 from 1268 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 9:
If we divide 6270 by 641, we get 9 and a remainder of 501.
The next digit of our result is 9. 
Result so far: 48891.9
Subtracting 5769 from 6270 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Let's proceed to step 10:
If we divide 5010 by 641, we get 7 and a remainder of 523.
Write down 7 as next digit of the result. 
Result so far: 48891.97
Subtract 4487 from 5010 to get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 11:
641 goes into 5230 8 times with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 48891.978
If we take 5128 away from 5230, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 12:
If we divide 1020 by 641, we get 1 and a remainder of 379.
Put 1 as the next digit of the answer. 
Result so far: 48891.9781
The remainder is 379 after subtracting 641 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 13:
If we divide 3790 by 641, we get 5 and a remainder of 585.
Record the quotient 5 as the next digit in the result. 
Result so far: 48891.97815
Subtracting 3205 from 3790 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 14:
When dividing 5850 by 641, we get 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 48891.978159
The remainder is 81 after subtracting 5769 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 15:
641 can be fit into 810 1 times, resulting in a remainder of 169.
The number 1 becomes the next digit in our result. 
Result so far: 48891.9781591
Subtract 641 from 810 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 16:
1690 divided by 641 is 2 with a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 48891.97815912
Subtract 1282 from 1690 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Our division results in 48891.97815912 with a remaining 4.08e-07.
