We look at the division of 17008 by 42 
We want to divide 17008 by 42.

Moving on to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 42

Step 2:
42 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 42

Advancing to step 3:
42 goes into 170 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 168 from 170 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 42

Advancing to step 4:
If we divide 20 by 42, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 20, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 42

On to step 5:
The number 42 fits into 208 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
If we take 168 away from 208, we end up 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.

Step 6:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 404.9
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 404.95
Subtracting 210 from 220 leaves us with 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 8:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 404.952
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.

Step 9:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 404.9523
If we take 126 away from 160, we end up 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.

Moving on to step 10:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 404.95238
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 11:
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: 404.95238
If we take 0 away from 40, we end up 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.

Step 12:
400 divided by 42 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 404.9523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
When dividing 220 by 42, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 404.95238095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 404.95238095 with a remainder of 1e-08.
