We look at the division of 86074 by 79 
Let's see how many times 79 fits into 86074.

Going ahead to step 1:
The number 79 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 79

Moving on to step 2:
86 divided by 79 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 79 from 86 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 79

Step 3:
79 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 70, we end up with 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 79

On to step 4:
The number 79 fits into 707 8 times, leaving a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 632 from 707 and we're left with 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 79

Advancing to step 5:
79 can be fit into 754 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 1089.0
If we subtract 711 from 754, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 6:
430 divided by 79 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1089.5
Deduct 395 from 430 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 79 fits into 350 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 1089.54
Subtracting 316 from 350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
If we divide 340 by 79, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1089.544
Subtracting 316 from 340 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 1089.544 with a balance of 0.0024.
