We look at the division of 487318 by 42 
Our goal is to divide 487318 by 42.

Advancing to step 1:
42 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 42

On to step 2:
The number 42 fits into 48 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 42 from 48 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 42

Let's proceed to step 3:
42 can be fit into 67 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 42 from 67, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 42

On to step 4:
42 can be fit into 253 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we subtract 252 from 253, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 42

On to step 5:
When dividing 11 by 42, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 1160.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 42

Moving on to step 6:
42 goes into 118 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 11602.0
If we subtract 84 from 118, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 11602.8
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11602.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 11602.809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
If we divide 220 by 42, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 11602.8095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 11602.80952
Deduct 84 from 100 and we're left 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 12:
The number 42 fits into 160 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 11602.809523
Deduct 126 from 160 and we're left 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.

Let's proceed to step 13:
340 divided by 42 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 11602.8095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11602.8095238
Subtracting 0 from 40 leaves us 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.

Our division results in 11602.8095238 with a remaining 4e-08.
