52831571 divided by 638 
Our goal is to divide 52831571 by 638.

Step 1:
If we divide 5 by 638, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 638

Going ahead to step 2:
52 divided by 638 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 638

Step 3:
528 divided by 638 is 0 with a remainder of 528.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 528, we get 528.
Fetch the next digit (3) from the dividend, attach it to 528 and continue: 5283 / 638

Advancing to step 4:
5283 divided by 638 is 8 with a remainder of 179.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5104 from 5283 to get 179.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 638

Step 5:
638 can be fit into 1791 2 times, resulting in a remainder of 515.
The next digit of our result is 2. 
Result so far: 82.0
If we take 1276 away from 1791, we end up with 515.
Take the next digit (5) from the dividend and append it to 515, then repeat: 5155 / 638

On to step 6:
If we divide 5155 by 638, we get 8 and a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 828.0
Subtract 5104 from 5155 to get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 638

Moving on to step 7:
638 goes into 517 0 times with a remainder of 517.
Put 0 as the next digit of the answer. 
Result so far: 8280.0
Deduct 0 from 517 and we're left with 517.
Append the next digit (1) from the dividend to 517 and continue with: 5171 / 638

Moving on to step 8:
When dividing 5171 by 638, we get 8 with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 82808.0
Subtracting 5104 from 5171 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
670 divided by 638 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 82808.1
Subtracting 638 from 670 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
638 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 82808.1
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
The number 638 fits into 3200 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 82808.105
If we subtract 3190 from 3200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
638 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 82808.105
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
1000 divided by 638 is 1 with a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 82808.10501
Subtracting 638 from 1000 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 14:
If we divide 3620 by 638, we get 5 and a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 82808.105015
Deduct 3190 from 3620 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 15:
If we divide 4300 by 638, we get 6 and a remainder of 472.
The number 6 becomes the next digit in our result. 
Result so far: 82808.1050156
If we subtract 3828 from 4300, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 16:
When dividing 4720 by 638, we get 7 with a remainder of 254.
Put 7 as the next digit of the answer. 
Result so far: 82808.10501567
Subtract 4466 from 4720 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 82808.10501567, with a leftover of 2.54e-07.
