We look at the division of 44435120 by 421 
Our goal is to divide 44435120 by 421.

Going ahead to step 1:
When dividing 4 by 421, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 421

Step 2:
421 can be fit into 44 0 times, resulting in a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 421

On to step 3:
If we divide 444 by 421, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 421 from 444 leaves us with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 421

On to step 4:
421 goes into 233 0 times with a remainder of 233.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 233 and we're left with 233.
Grab the next digit (5) from the dividend, add it to 233, then carry on: 2335 / 421

Going ahead to step 5:
If we divide 2335 by 421, we get 5 and a remainder of 230.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 230 after subtracting 2105 from 2335.
Bring next digit (1) of the dividend behind the 230 and repeat the process: 2301 / 421

Step 6:
2301 divided by 421 is 5 with a remainder of 196.
The number 5 becomes the next digit in our result. 
Result so far: 1055.0
Subtracting 2105 from 2301 leaves us with 196.
Take the next digit (2) from the dividend and append it to 196, then repeat: 1962 / 421

Going ahead to step 7:
421 goes into 1962 4 times with a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 10554.0
Deduct 1684 from 1962 and we're left with 278.
Include the next digit (0) from the dividend after 278, then repeat: 2780 / 421

Going ahead to step 8:
2780 divided by 421 is 6 with a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 105546.0
Deduct 2526 from 2780 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
The number 421 fits into 2540 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 105546.6
Subtract 2526 from 2540 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
The number 421 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 105546.6
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
421 can be fit into 1400 3 times, resulting in a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 105546.603
If we take 1263 away from 1400, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 12:
When dividing 1370 by 421, we get 3 with a remainder of 107.
The next digit of our result is 3. 
Result so far: 105546.6033
If we take 1263 away from 1370, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 105546.6033 with a remainder of 0.00107.
