443430 ÷ 42 
We want to divide 443430 by 42.

On to step 1:
4 divided by 42 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 42

On to step 2:
42 can be fit into 44 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 42 from 44.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

Moving on to step 3:
If we divide 23 by 42, we get 0 and a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 23 to get 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 42

Going ahead to step 4:
When dividing 234 by 42, we get 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 210 from 234 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 42

On to step 5:
42 can be fit into 243 5 times, resulting in a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 1055.0
If we take 210 away from 243, we end up with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 42

Moving on to step 6:
42 can be fit into 330 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 10557.0
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 10557.8
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10557.85
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 42, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10557.857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 10557.8571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 10557.85714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 10557.857142
If we subtract 84 from 120, we 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.

Going ahead to step 13:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10557.8571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10557.85714285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 10557.85714285, and the remainder is 3e-08.
