42108 ÷ 9 
We're looking to find how many times 9 goes into 42108.

On to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 9

On to step 2:
The number 9 fits into 42 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 36 away from 42, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 9

Step 3:
If we divide 61 by 9, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 54 away from 61, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 9

Moving on to step 4:
If we divide 70 by 9, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 467.0
If we subtract 63 from 70, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 9

Going ahead to step 5:
9 can be fit into 78 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4678.0
Subtract 72 from 78 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 6:
If we divide 60 by 9, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4678.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 9, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4678.66
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4678.66 with a remainder of 0.006.
