We look at the division of 86128477 by 79 
Let's see how many times 79 fits into 86128477.

Going ahead to step 1:
8 divided by 79 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 79

On to step 2:
79 goes into 86 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 79 away from 86, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 79

Step 3:
71 divided by 79 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 79

Step 4:
79 can be fit into 712 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 711 from 712 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 79

Let's proceed to step 5:
If we divide 18 by 79, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 1090.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 79

Let's proceed to step 6:
If we divide 184 by 79, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 10902.0
Deduct 158 from 184 and we're left with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 79

Moving on to step 7:
The number 79 fits into 267 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 109023.0
Subtracting 237 from 267 leaves us with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 79

Going ahead to step 8:
79 can be fit into 307 3 times, resulting in a remainder of 70.
The next digit of our result is 3. 
Result so far: 1090233.0
Subtracting 237 from 307 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
700 divided by 79 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 1090233.8
If we subtract 632 from 700, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
If we divide 680 by 79, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1090233.88
If we take 632 away from 680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 1090233.88 with a remaining 0.048.
