We look at the division of 800878 by 86 
We're looking to find how many times 86 goes into 800878.

Step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 86

Step 2:
86 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 86

Step 3:
The number 86 fits into 800 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 774 from 800 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 86

Moving on to step 4:
When dividing 268 by 86, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 93.0
If we subtract 258 from 268, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 86

Going ahead to step 5:
86 can be fit into 107 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 931.0
Subtracting 86 from 107 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 86

Step 6:
If we divide 218 by 86, we get 2 and a remainder of 46.
The next digit of our result is 2. 
Result so far: 9312.0
Deduct 172 from 218 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.

Advancing to step 7:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9312.5
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 86, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9312.53
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
86 goes into 420 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 9312.534
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 10:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 9312.5348
Deduct 688 from 760 and we're left with 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 11:
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: 9312.53488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 9312.53488 with a balance of 3.2e-05.
