We divide 999901 by 86
We're looking to find how many times 86 goes into 999901.

Step 1:
86 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 86

Going ahead to step 2:
If we divide 99 by 86, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 86 from 99 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 86

On to step 3:
When dividing 139 by 86, we get 1 with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 86 from 139 leaves us with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 86

Moving on to step 4:
The number 86 fits into 539 6 times, leaving a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 116.0
Deduct 516 from 539 and we're left with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 86

Advancing to step 5:
86 goes into 230 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 1162.0
Subtract 172 from 230 to get 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 86

Going ahead to step 6:
581 divided by 86 is 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 11626.0
If we subtract 516 from 581, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
86 can be fit into 650 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 11626.7
If we take 602 away from 650, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 11626.75
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 11626.755
Subtract 430 from 500 to get 70.
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 11626.755 with a remaining 0.007.
