Let's divide 82113798 by 639
Our goal is to divide 82113798 by 639.

On to step 1:
When dividing 8 by 639, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 639

On to step 2:
If we divide 82 by 639, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 639

Step 3:
639 goes into 821 1 times with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 182 after subtracting 639 from 821.
Append the next digit (1) from the dividend to 182 and continue with: 1821 / 639

On to step 4:
1821 divided by 639 is 2 with a remainder of 543.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1278 from 1821 leaves us with 543.
Include the next digit (3) from the dividend after 543, then repeat: 5433 / 639

Moving on to step 5:
When dividing 5433 by 639, we get 8 with a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 5112 from 5433 leaves us with 321.
Fetch the next digit (7) from the dividend, attach it to 321 and continue: 3217 / 639

Moving on to step 6:
639 goes into 3217 5 times with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 1285.0
The remainder is 22 after subtracting 3195 from 3217.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 639

Step 7:
When dividing 229 by 639, we get 0 with a remainder of 229.
Use 0 as the next digit of our solution. 
Result so far: 12850.0
If we take 0 away from 229, we end up with 229.
Append the next digit (8) from the dividend to 229 and continue with: 2298 / 639

Advancing to step 8:
If we divide 2298 by 639, we get 3 and a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 128503.0
Subtract 1917 from 2298 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 9:
639 goes into 3810 5 times with a remainder of 615.
Put 5 as the next digit of the answer. 
Result so far: 128503.5
If we take 3195 away from 3810, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 10:
If we divide 6150 by 639, we get 9 and a remainder of 399.
Record the quotient 9 as the next digit in the result. 
Result so far: 128503.59
Subtracting 5751 from 6150 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 11:
If we divide 3990 by 639, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 128503.596
The remainder is 156 after subtracting 3834 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
1560 divided by 639 is 2 with a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 128503.5962
Subtract 1278 from 1560 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 13:
The number 639 fits into 2820 4 times, leaving a remainder of 264.
The next digit of our result is 4. 
Result so far: 128503.59624
If we take 2556 away from 2820, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 14:
639 can be fit into 2640 4 times, resulting in a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 128503.596244
Subtracting 2556 from 2640 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 128503.596244, with a leftover of 8.4e-06.
