We look at the division of 978872 by 86 
We want to divide 978872 by 86.

Let's proceed to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 86

Let's proceed to step 2:
If we divide 97 by 86, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 86 away from 97, we end up with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 86

Moving on to step 3:
118 divided by 86 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 86 from 118, we get 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 86

Step 4:
The number 86 fits into 328 3 times, leaving a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Deduct 258 from 328 and we're left with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 86

On to step 5:
The number 86 fits into 707 8 times, leaving a remainder of 19.
The next digit of our result is 8. 
Result so far: 1138.0
Subtract 688 from 707 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 86

Let's proceed to step 6:
The number 86 fits into 192 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 11382.0
Subtract 172 from 192 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 86 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 11382.2
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 11382.23
The remainder is 22 after subtracting 258 from 280.
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 9:
220 divided by 86 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 11382.232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 86 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 11382.2325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
500 divided by 86 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 11382.23255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 11382.23255 with a remaining 7e-05.
