215900 divided by 24 
We want to figure out the number of times 215900 can be divided by 24.

On to step 1:
If we divide 2 by 24, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 24

Moving on to step 2:
If we divide 21 by 24, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 24

Let's proceed to step 3:
The number 24 fits into 215 8 times, leaving a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 192 from 215 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 24

Advancing to step 4:
239 divided by 24 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 216 from 239 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 24

Moving on to step 5:
24 goes into 230 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 899.0
Deduct 216 from 230 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 24

On to step 6:
24 can be fit into 140 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 8995.0
The remainder is 20 after subtracting 120 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 24 fits into 200 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8995.8
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
24 goes into 80 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 8995.83
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 24, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 8995.833
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 8995.833 with a remaining 0.0008.
