We're dividing 800965 by 86 
We want to figure out the number of times 800965 can be divided by 86.

Step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 86

On to step 2:
If we divide 80 by 86, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 86

Advancing to step 3:
When dividing 800 by 86, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 774 from 800 to get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 86

On to step 4:
269 divided by 86 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 93.0
Subtract 258 from 269 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 86

Step 5:
If we divide 116 by 86, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 931.0
Deduct 86 from 116 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 86

Moving on to step 6:
The number 86 fits into 305 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 9313.0
The remainder is 47 after subtracting 258 from 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
When dividing 470 by 86, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9313.5
Subtracting 430 from 470 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
86 goes into 400 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 9313.54
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 86, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 9313.546
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9313.5465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 9313.54651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 9313.546511
Subtracting 86 from 140 leaves us 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.

The final result is 9313.546511 with a remainder of 5.4e-06.
