We're dividing 121985 by 24 
We want to divide 121985 by 24.

Moving on to step 1:
When dividing 1 by 24, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 24

Step 2:
12 divided by 24 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 24

Moving on to step 3:
24 can be fit into 121 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 120 from 121 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 24

Step 4:
24 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 24

Let's proceed to step 5:
The number 24 fits into 198 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 508.0
The remainder is 6 after subtracting 192 from 198.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 24

Advancing to step 6:
The number 24 fits into 65 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 5082.0
If we subtract 48 from 65, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 24 fits into 170 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 5082.7
Subtract 168 from 170 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.

Advancing to step 8:
24 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 5082.7
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 24, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 5082.708
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.

Going ahead to step 10:
The number 24 fits into 80 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 5082.7083
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 5082.70833
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 5082.70833 and a remainder of 8e-06.
