217524 divided by 86 
We want to divide 217524 by 86.

Going ahead to step 1:
86 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 86

Moving on to step 2:
When dividing 21 by 86, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 86

Moving on to step 3:
86 goes into 217 2 times with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 172 from 217 leaves us with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 86

Moving on to step 4:
455 divided by 86 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 430 from 455 and we're left with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 86

Advancing to step 5:
86 can be fit into 252 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 252.0
Subtract 172 from 252 to get 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 86

Advancing to step 6:
The number 86 fits into 804 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 2529.0
Subtract 774 from 804 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 2529.3
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.

On to step 8:
420 divided by 86 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 2529.34
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 2529.348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
When dividing 720 by 86, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 2529.3488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 2529.3488 with a remainder of 0.00032.
