We look at the division of 421081 by 24 
Our goal is to divide 421081 by 24.

Step 1:
When dividing 4 by 24, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 24

Moving on to step 2:
24 can be fit into 42 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 24 from 42.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 24

Advancing to step 3:
24 can be fit into 181 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 168 from 181 to get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 24

Going ahead to step 4:
When dividing 130 by 24, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 175.0
Subtract 120 from 130 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 24

Moving on to step 5:
108 divided by 24 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1754.0
If we take 96 away from 108, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 24

On to step 6:
The number 24 fits into 121 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 17545.0
Subtract 120 from 121 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 24 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17545.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
24 goes into 100 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 17545.04
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 24 fits into 40 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 17545.041
If we take 24 away from 40, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 24, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 17545.0416
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
24 goes into 160 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 17545.04166
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 17545.04166, with a leftover of 1.6e-05.
