Let's divide 30239889 by 421
Our goal is to divide 30239889 by 421.

Advancing to step 1:
421 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 421

Let's proceed to step 2:
421 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 421

Step 3:
421 can be fit into 302 0 times, resulting in a remainder of 302.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 302 to get 302.
Include the next digit (3) from the dividend after 302, then repeat: 3023 / 421

Step 4:
421 goes into 3023 7 times with a remainder of 76.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 2947 from 3023 leaves us with 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 421

Let's proceed to step 5:
When dividing 769 by 421, we get 1 with a remainder of 348.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 421 from 769 leaves us with 348.
Bring next digit (8) of the dividend behind the 348 and repeat the process: 3488 / 421

Step 6:
If we divide 3488 by 421, we get 8 and a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
Subtract 3368 from 3488 to get 120.
Append the next digit (8) from the dividend to 120 and continue with: 1208 / 421

Going ahead to step 7:
If we divide 1208 by 421, we get 2 and a remainder of 366.
The number 2 becomes the next digit in our result. 
Result so far: 7182.0
The remainder is 366 after subtracting 842 from 1208.
Bring next digit (9) of the dividend behind the 366 and repeat the process: 3669 / 421

On to step 8:
When dividing 3669 by 421, we get 8 with a remainder of 301.
Use 8 as the next digit of our solution. 
Result so far: 71828.0
Subtracting 3368 from 3669 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
When dividing 3010 by 421, we get 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 71828.7
Subtracting 2947 from 3010 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
421 can be fit into 630 1 times, resulting in a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 71828.71
Subtract 421 from 630 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 11:
421 can be fit into 2090 4 times, resulting in a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 71828.714
Subtracting 1684 from 2090 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 12:
421 goes into 4060 9 times with a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 71828.7149
If we subtract 3789 from 4060, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 13:
The number 421 fits into 2710 6 times, leaving a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 71828.71496
Subtracting 2526 from 2710 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 14:
The number 421 fits into 1840 4 times, leaving a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 71828.714964
Subtract 1684 from 1840 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 15:
421 goes into 1560 3 times with a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 71828.7149643
Deduct 1263 from 1560 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 16:
The number 421 fits into 2970 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 71828.71496437
If we subtract 2947 from 2970, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 71828.71496437 with a balance of 2.3e-08.
