We're dividing 153969 by 24 
Our goal is to divide 153969 by 24.

Going ahead to step 1:
24 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 24

Let's proceed to step 2:
If we divide 15 by 24, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 24

Moving on to step 3:
When dividing 153 by 24, we get 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 9 after subtracting 144 from 153.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 24

Moving on to step 4:
24 can be fit into 99 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 96 from 99 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 24

Going ahead to step 5:
36 divided by 24 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Subtract 24 from 36 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 24

On to step 6:
If we divide 129 by 24, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 6415.0
If we subtract 120 from 129, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
24 goes into 90 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 6415.3
If we take 72 away from 90, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
24 can be fit into 180 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 6415.37
Subtract 168 from 180 to get 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:
The number 24 fits into 120 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6415.375
If we subtract 120 from 120, we 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.

Step 10:
0 divided by 24 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6415.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6415.375
Deduct 0 from 0 and we're left 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.

The final result is 6415.375 with a remainder of 0.0.
