631856 ÷ 42 
We're looking to find how many times 42 goes into 631856.

Step 1:
6 divided by 42 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 42

Advancing to step 2:
63 divided by 42 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 21 after subtracting 42 from 63.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 42

Let's proceed to step 3:
211 divided by 42 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 210 from 211, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 42

Step 4:
The number 42 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 18, we end up with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 42

Moving on to step 5:
42 goes into 185 4 times with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 1504.0
The remainder is 17 after subtracting 168 from 185.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 42

Advancing to step 6:
When dividing 176 by 42, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 15044.0
Subtracting 168 from 176 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 42, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 15044.1
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 15044.19
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15044.19
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 15044.1904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
42 goes into 320 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 15044.19047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
When dividing 260 by 42, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 15044.190476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 15044.1904761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 15044.19047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15044.19047619 and a remainder of 2e-09.
