Let's divide 79455 by 86
Let's see how many times 86 fits into 79455.

Step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 86

On to step 2:
When dividing 79 by 86, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 86

Let's proceed to step 3:
86 goes into 794 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 9.0
If we take 774 away from 794, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 86

Moving on to step 4:
86 can be fit into 205 2 times, resulting in a remainder of 33.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 172 from 205 leaves us with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 86

Moving on to step 5:
The number 86 fits into 335 3 times, leaving a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 923.0
The remainder is 77 after subtracting 258 from 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 6:
86 goes into 770 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 923.8
Subtract 688 from 770 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 7:
When dividing 820 by 86, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 923.89
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 923.895
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
300 divided by 86 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 923.8953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 86 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 923.89534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 86 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 923.895348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 923.8953488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 923.8953488 and a remainder of 3.2e-07.
