Let's divide 486189 by 24
We want to figure out the number of times 486189 can be divided by 24.

Step 1:
4 divided by 24 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 24

On to step 2:
The number 24 fits into 48 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 48 from 48 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 24

Moving on to step 3:
When dividing 6 by 24, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 24

On to step 4:
24 can be fit into 61 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
If we take 48 away from 61, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 24

On to step 5:
If we divide 138 by 24, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 2025.0
The remainder is 18 after subtracting 120 from 138.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 24

Moving on to step 6:
If we divide 189 by 24, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 20257.0
If we subtract 168 from 189, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 24 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 20257.8
The remainder is 18 after subtracting 192 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
24 goes into 180 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 20257.87
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 24, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20257.875
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 24, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20257.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 24, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20257.875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 20257.875, with a leftover of 0.0.
