We look at the division of 811855 by 79 
Let's see how many times 79 fits into 811855.

Moving on to step 1:
8 divided by 79 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 79

On to step 2:
When dividing 81 by 79, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 79 from 81 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 79

Let's proceed to step 3:
The number 79 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 79

On to step 4:
79 goes into 218 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 158 from 218 leaves us with 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 79

Step 5:
If we divide 605 by 79, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
If we take 553 away from 605, we end up with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 79

Moving on to step 6:
79 can be fit into 525 6 times, resulting in a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 10276.0
Deduct 474 from 525 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
The number 79 fits into 510 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 10276.6
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
79 goes into 360 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 10276.64
Subtracting 316 from 360 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
79 can be fit into 440 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 10276.645
Subtract 395 from 440 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
79 can be fit into 450 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 10276.6455
Subtract 395 from 450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 10276.6455, with a leftover of 0.00055.
