We're dividing 318135 by 42 
Let's see how many times 42 fits into 318135.

Advancing to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 42

Advancing to step 2:
When dividing 31 by 42, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 42

Going ahead to step 3:
If we divide 318 by 42, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 294 from 318 and we're left with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 42

Moving on to step 4:
42 can be fit into 241 5 times, resulting in a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Deduct 210 from 241 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 42

Step 5:
42 can be fit into 313 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 757.0
If we subtract 294 from 313, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 42

Step 6:
195 divided by 42 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 7574.0
Deduct 168 from 195 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
42 goes into 270 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 7574.6
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 7574.64
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 7574.642
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 7574.6428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 7574.64285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7574.642857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 7574.6428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 7574.64285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 7574.64285714 with a remaining 1.2e-08.
