We look at the division of 816387 by 79 
Let's see how many times 79 fits into 816387.

Step 1:
8 divided by 79 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 79

Moving on to step 2:
79 can be fit into 81 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 79 from 81 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 79

Step 3:
The number 79 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 79

Step 4:
When dividing 263 by 79, we get 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtracting 237 from 263 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 79

On to step 5:
If we divide 268 by 79, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1033.0
If we subtract 237 from 268, we get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 79

On to step 6:
79 goes into 317 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 10334.0
The remainder is 1 after subtracting 316 from 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 79, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 10334.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 79 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 10334.01
Subtract 79 from 100 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
79 can be fit into 210 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 10334.012
Subtracting 158 from 210 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
79 can be fit into 520 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 10334.0126
If we subtract 474 from 520, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
460 divided by 79 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 10334.01265
Subtracting 395 from 460 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
79 can be fit into 650 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 10334.012658
If we subtract 632 from 650, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
180 divided by 79 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 10334.0126582
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
If we divide 220 by 79, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 10334.01265822
If we subtract 158 from 220, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 10334.01265822 and a remainder of 6.2e-08.
