631743 ÷ 42 
We're looking to find how many times 42 goes into 631743.

Moving on to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 42

On to step 2:
When dividing 63 by 42, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 63, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 42

Step 3:
When dividing 211 by 42, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 210 from 211 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 42

On to step 4:
42 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we take 0 away from 17, we end up with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 42

Going ahead to step 5:
42 can be fit into 174 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1504.0
Subtract 168 from 174 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 42

On to step 6:
The number 42 fits into 63 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 15041.0
If we take 42 away from 63, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
42 goes into 210 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15041.5
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15041.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
42 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15041.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15041.5 with a remaining 0.0.
