We look at the division of 480318 by 42 
We want to figure out the number of times 480318 can be divided by 42.

Step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 42

Step 2:
If we divide 48 by 42, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 48 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 42

Let's proceed to step 3:
60 divided by 42 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 42 away from 60, we end up with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 42

On to step 4:
The number 42 fits into 183 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 168 away from 183, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 42

Going ahead to step 5:
When dividing 151 by 42, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1143.0
If we take 126 away from 151, we end up with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 42

On to step 6:
42 goes into 258 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 11436.0
Subtracting 252 from 258 leaves us 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.

Advancing to step 7:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 11436.1
The remainder is 18 after subtracting 42 from 60.
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 8:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 11436.14
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.

Going ahead to step 9:
42 goes into 120 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 11436.142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 11436.1428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11436.14285
Subtract 210 from 240 to get 30.
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:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 11436.142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
42 goes into 60 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 11436.1428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11436.14285714
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.

The final result is 11436.14285714 with a remainder of 1.2e-08.
