We're dividing 816755 by 86 
We want to figure out the number of times 816755 can be divided by 86.

Going ahead to step 1:
8 divided by 86 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 86

Advancing to step 2:
86 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 86

Going ahead to step 3:
The number 86 fits into 816 9 times, leaving a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 774 from 816 and we're left with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 86

Advancing to step 4:
When dividing 427 by 86, we get 4 with a remainder of 83.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtract 344 from 427 to get 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 86

Step 5:
86 can be fit into 835 9 times, resulting in a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 949.0
Subtract 774 from 835 to get 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 86

Going ahead to step 6:
If we divide 615 by 86, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9497.0
Deduct 602 from 615 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 86, we get 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 9497.1
Deduct 86 from 130 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9497.15
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 86, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 9497.151
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 9497.1511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 9497.1511 with a remaining 0.00054.
