31980795 divided by 638 
We're looking to find how many times 638 goes into 31980795.

On to step 1:
3 divided by 638 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 638

Step 2:
638 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 638

On to step 3:
If we divide 319 by 638, we get 0 and a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Take the next digit (8) from the dividend and append it to 319, then repeat: 3198 / 638

Advancing to step 4:
638 goes into 3198 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3190 from 3198 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 638

On to step 5:
638 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 80, we end up with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 638

Going ahead to step 6:
The number 638 fits into 807 1 times, leaving a remainder of 169.
The next digit of our result is 1. 
Result so far: 501.0
Subtracting 638 from 807 leaves us with 169.
Append the next digit (9) from the dividend to 169 and continue with: 1699 / 638

Step 7:
638 goes into 1699 2 times with a remainder of 423.
Record the quotient 2 as the next digit in the result. 
Result so far: 5012.0
If we take 1276 away from 1699, we end up with 423.
Fetch the next digit (5) from the dividend, attach it to 423 and continue: 4235 / 638

Step 8:
638 goes into 4235 6 times with a remainder of 407.
Record the quotient 6 as the next digit in the result. 
Result so far: 50126.0
If we take 3828 away from 4235, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 9:
The number 638 fits into 4070 6 times, leaving a remainder of 242.
Put 6 as the next digit of the answer. 
Result so far: 50126.6
Subtract 3828 from 4070 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
If we divide 2420 by 638, we get 3 and a remainder of 506.
Use 3 as the next digit of our solution. 
Result so far: 50126.63
Subtracting 1914 from 2420 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.

Going ahead to step 11:
When dividing 5060 by 638, we get 7 with a remainder of 594.
Record the quotient 7 as the next digit in the result. 
Result so far: 50126.637
If we take 4466 away from 5060, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 12:
5940 divided by 638 is 9 with a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 50126.6379
If we subtract 5742 from 5940, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 13:
When dividing 1980 by 638, we get 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 50126.63793
Deduct 1914 from 1980 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
638 can be fit into 660 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 50126.637931
Subtract 638 from 660 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 15:
638 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 50126.637931
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 16:
The number 638 fits into 2200 3 times, leaving a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 50126.63793103
If we subtract 1914 from 2200, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The quotient of the division is 50126.63793103, and the remainder is 2.86e-07.
