940090 ÷ 42 
Let's see how many times 42 fits into 940090.

Advancing to step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 42

Advancing to step 2:
42 goes into 94 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 84 away from 94, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 42

Moving on to step 3:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 84 from 100 to get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 42

Step 4:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we subtract 126 from 160, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 42

Going ahead to step 5:
If we divide 349 by 42, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 2238.0
Subtract 336 from 349 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 42

Advancing to step 6:
The number 42 fits into 130 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 22383.0
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 22383.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 42, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 22383.09
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 22383.095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 22383.0952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 42 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 22383.09523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
When dividing 340 by 42, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 22383.095238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
42 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 22383.095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
If we divide 400 by 42, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 22383.09523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 22383.09523809 with a remainder of 2.2e-08.
