943291 ÷ 42 
We're looking to find how many times 42 goes into 943291.

Going ahead to step 1:
42 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 42

Moving on to step 2:
The number 42 fits into 94 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 42

Advancing to step 3:
If we divide 103 by 42, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 84 from 103 leaves us with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 42

On to step 4:
42 goes into 192 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 224.0
Subtracting 168 from 192 leaves us with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 42

Going ahead to step 5:
42 goes into 249 5 times with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 2245.0
If we take 210 away from 249, we end up with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 42

On to step 6:
391 divided by 42 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 22459.0
Deduct 378 from 391 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
42 can be fit into 130 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 22459.3
Deduct 126 from 130 and we're left 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.

Going ahead to step 8:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 22459.3
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.

Let's proceed to step 9:
When dividing 400 by 42, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 22459.309
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.

Let's proceed to step 10:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 22459.3095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 22459.30952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
160 divided by 42 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 22459.309523
Deduct 126 from 160 and we're left 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.

Step 13:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 22459.3095238
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.

Advancing to step 14:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 22459.3095238
Subtract 0 from 40 to 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.

After the division, we end up with 22459.3095238 and a remainder of 4e-08.
