14152508 ÷ 421 
We want to divide 14152508 by 421.

Going ahead to step 1:
When dividing 1 by 421, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 421

Moving on to step 2:
If we divide 14 by 421, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 421

Going ahead to step 3:
If we divide 141 by 421, we get 0 and a remainder of 141.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 141, we get 141.
Fetch the next digit (5) from the dividend, attach it to 141 and continue: 1415 / 421

Step 4:
1415 divided by 421 is 3 with a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1263 from 1415 and we're left with 152.
Fetch the next digit (2) from the dividend, attach it to 152 and continue: 1522 / 421

Going ahead to step 5:
If we divide 1522 by 421, we get 3 and a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 259 after subtracting 1263 from 1522.
Take the next digit (5) from the dividend and append it to 259, then repeat: 2595 / 421

Advancing to step 6:
421 goes into 2595 6 times with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 336.0
If we take 2526 away from 2595, we end up with 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 421

Let's proceed to step 7:
The number 421 fits into 690 1 times, leaving a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 3361.0
The remainder is 269 after subtracting 421 from 690.
Include the next digit (8) from the dividend after 269, then repeat: 2698 / 421

Moving on to step 8:
If we divide 2698 by 421, we get 6 and a remainder of 172.
Record the quotient 6 as the next digit in the result. 
Result so far: 33616.0
Subtracting 2526 from 2698 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 9:
When dividing 1720 by 421, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 33616.4
Subtract 1684 from 1720 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
360 divided by 421 is 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 33616.4
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
The number 421 fits into 3600 8 times, leaving a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 33616.408
Deduct 3368 from 3600 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
When dividing 2320 by 421, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 33616.4085
Subtract 2105 from 2320 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 13:
421 can be fit into 2150 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 33616.40855
If we subtract 2105 from 2150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 33616.40855 with a balance of 4.5e-05.
