We look at the division of 82139075 by 869 
We're looking to find how many times 869 goes into 82139075.

Step 1:
869 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 869

On to step 2:
82 divided by 869 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 869

Advancing to step 3:
869 can be fit into 821 0 times, resulting in a remainder of 821.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 821 after subtracting 0 from 821.
Grab the next digit (3) from the dividend, add it to 821, then carry on: 8213 / 869

Going ahead to step 4:
The number 869 fits into 8213 9 times, leaving a remainder of 392.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 7821 from 8213, we get 392.
Fetch the next digit (9) from the dividend, attach it to 392 and continue: 3929 / 869

Going ahead to step 5:
869 can be fit into 3929 4 times, resulting in a remainder of 453.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 3476 from 3929 to get 453.
Take the next digit (0) from the dividend and append it to 453, then repeat: 4530 / 869

Moving on to step 6:
869 can be fit into 4530 5 times, resulting in a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 945.0
If we subtract 4345 from 4530, we get 185.
Append the next digit (7) from the dividend to 185 and continue with: 1857 / 869

Going ahead to step 7:
When dividing 1857 by 869, we get 2 with a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 9452.0
The remainder is 119 after subtracting 1738 from 1857.
Fetch the next digit (5) from the dividend, attach it to 119 and continue: 1195 / 869

Going ahead to step 8:
869 goes into 1195 1 times with a remainder of 326.
The number 1 becomes the next digit in our result. 
Result so far: 94521.0
Deduct 869 from 1195 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 9:
869 goes into 3260 3 times with a remainder of 653.
The next digit of our result is 3. 
Result so far: 94521.3
The remainder is 653 after subtracting 2607 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 10:
If we divide 6530 by 869, we get 7 and a remainder of 447.
Use 7 as the next digit of our solution. 
Result so far: 94521.37
Subtracting 6083 from 6530 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 11:
When dividing 4470 by 869, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 94521.375
Subtract 4345 from 4470 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
869 goes into 1250 1 times with a remainder of 381.
The number 1 becomes the next digit in our result. 
Result so far: 94521.3751
Deduct 869 from 1250 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 13:
869 goes into 3810 4 times with a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 94521.37514
Subtract 3476 from 3810 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 14:
If we divide 3340 by 869, we get 3 and a remainder of 733.
Write down 3 as next digit of the result. 
Result so far: 94521.375143
Deduct 2607 from 3340 and we're left with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Advancing to step 15:
When dividing 7330 by 869, we get 8 with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 94521.3751438
Deduct 6952 from 7330 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 16:
If we divide 3780 by 869, we get 4 and a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 94521.37514384
If we subtract 3476 from 3780, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 94521.37514384, with a leftover of 3.04e-07.
