14379936 divided by 421 
Our goal is to divide 14379936 by 421.

Step 1:
The number 421 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 421

Let's proceed to step 2:
421 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 421

Step 3:
421 can be fit into 143 0 times, resulting in a remainder of 143.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 143, we end up with 143.
Grab the next digit (7) from the dividend, add it to 143, then carry on: 1437 / 421

Moving on to step 4:
1437 divided by 421 is 3 with a remainder of 174.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1263 from 1437 leaves us with 174.
Grab the next digit (9) from the dividend, add it to 174, then carry on: 1749 / 421

Let's proceed to step 5:
421 can be fit into 1749 4 times, resulting in a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 65 after subtracting 1684 from 1749.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 421

Let's proceed to step 6:
The number 421 fits into 659 1 times, leaving a remainder of 238.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
Deduct 421 from 659 and we're left with 238.
Append the next digit (3) from the dividend to 238 and continue with: 2383 / 421

Advancing to step 7:
421 goes into 2383 5 times with a remainder of 278.
Record the quotient 5 as the next digit in the result. 
Result so far: 3415.0
Deduct 2105 from 2383 and we're left with 278.
Take the next digit (6) from the dividend and append it to 278, then repeat: 2786 / 421

Step 8:
421 goes into 2786 6 times with a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 34156.0
Subtracting 2526 from 2786 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
The number 421 fits into 2600 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 34156.6
If we take 2526 away from 2600, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
When dividing 740 by 421, we get 1 with a remainder of 319.
Write down 1 as next digit of the result. 
Result so far: 34156.61
Subtract 421 from 740 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 11:
If we divide 3190 by 421, we get 7 and a remainder of 243.
The next digit of our result is 7. 
Result so far: 34156.617
Subtracting 2947 from 3190 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 12:
The number 421 fits into 2430 5 times, leaving a remainder of 325.
The next digit of our result is 5. 
Result so far: 34156.6175
If we take 2105 away from 2430, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 13:
421 can be fit into 3250 7 times, resulting in a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 34156.61757
Subtract 2947 from 3250 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 14:
3030 divided by 421 is 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 34156.617577
If we subtract 2947 from 3030, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 34156.617577 with a remainder of 8.3e-06.
