484981 ÷ 42 
Our goal is to divide 484981 by 42.

On to step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 42

Step 2:
When dividing 48 by 42, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 48, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 42

Going ahead to step 3:
The number 42 fits into 64 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 42 from 64 leaves us with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 42

On to step 4:
229 divided by 42 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
The remainder is 19 after subtracting 210 from 229.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 42

Advancing to step 5:
If we divide 198 by 42, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 1154.0
If we take 168 away from 198, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 42

On to step 6:
301 divided by 42 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 11547.0
Subtracting 294 from 301 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 42, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 11547.1
The remainder is 28 after subtracting 42 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 11547.16
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 42 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 11547.166
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 11547.166 and a remainder of 0.0028.
