We look at the division of 630955 by 42 
We're looking to find how many times 42 goes into 630955.

Step 1:
42 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 42

On to step 2:
The number 42 fits into 63 1 times, leaving 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.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 42

Step 3:
The number 42 fits into 210 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 210 from 210, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 42

Let's proceed to step 4:
9 divided by 42 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 9 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 42

Let's proceed to step 5:
When dividing 95 by 42, we get 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 1502.0
If we subtract 84 from 95, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 42

Moving on to step 6:
The number 42 fits into 115 2 times, leaving a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 15022.0
Deduct 84 from 115 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
When dividing 310 by 42, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 15022.7
If we take 294 away from 310, we end up 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.

Advancing to step 8:
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: 15022.73
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.

Going ahead to step 9:
42 goes into 340 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 15022.738
The remainder is 4 after subtracting 336 from 340.
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 10:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15022.738
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 15022.73809
Deduct 378 from 400 and we're left 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.

Going ahead to step 12:
42 goes into 220 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15022.738095
Deduct 210 from 220 and we're left 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.

On to step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15022.7380952
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.

Moving on to step 14:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 15022.73809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 15022.73809523, with a leftover of 3.4e-08.
