85621 ÷ 86 
We want to divide 85621 by 86.

On to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Let's proceed to step 2:
When dividing 85 by 86, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 86

Let's proceed to step 3:
The number 86 fits into 856 9 times, leaving a remainder of 82.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 774 from 856 and we're left with 82.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 86

Going ahead to step 4:
When dividing 822 by 86, we get 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 774 away from 822, we end up with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 86

Let's proceed to step 5:
If we divide 481 by 86, we get 5 and a remainder of 51.
The next digit of our result is 5. 
Result so far: 995.0
If we take 430 away from 481, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 6:
If we divide 510 by 86, we get 5 and a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 995.5
If we subtract 430 from 510, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
86 goes into 800 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 995.59
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 995.593
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 995.593
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 86, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 995.59302
Subtract 172 from 200 to 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.

Going ahead to step 11:
If we divide 280 by 86, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 995.593023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 995.5930232
The remainder is 48 after subtracting 172 from 220.
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 13:
480 divided by 86 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 995.59302325
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.

The final result is 995.59302325 with a remainder of 5e-08.
