12020449 ÷ 42 
We're looking to find how many times 42 goes into 12020449.

Moving on to step 1:
1 divided by 42 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 42

Step 2:
If we divide 12 by 42, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 42

On to step 3:
When dividing 120 by 42, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 84 from 120 and we're left with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 42

On to step 4:
362 divided by 42 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 336 from 362, we get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 42

On to step 5:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 286.0
The remainder is 8 after subtracting 252 from 260.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 42

On to step 6:
84 divided by 42 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2862.0
If we subtract 84 from 84, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 42

Going ahead to step 7:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 28620.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 42

Moving on to step 8:
42 can be fit into 49 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 286201.0
Subtracting 42 from 49 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
42 goes into 70 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 286201.1
Deduct 42 from 70 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 42, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 286201.16
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
42 can be fit into 280 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 286201.166
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 286201.166 and a remainder of 0.0028.
