We look at the division of 674215 by 18 
We want to divide 674215 by 18.

Advancing to step 1:
18 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 18

Let's proceed to step 2:
18 goes into 67 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 13 after subtracting 54 from 67.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 18

Step 3:
18 can be fit into 134 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 126 from 134, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 18

Advancing to step 4:
If we divide 82 by 18, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 374.0
If we take 72 away from 82, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 18

Let's proceed to step 5:
18 goes into 101 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 3745.0
Subtracting 90 from 101 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 18

Let's proceed to step 6:
18 goes into 115 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 37456.0
The remainder is 7 after subtracting 108 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
18 goes into 70 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 37456.3
Subtracting 54 from 70 leaves us 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 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 37456.38
Subtracting 144 from 160 leaves us 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.

Going ahead to step 9:
18 goes into 160 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 37456.388
Subtracting 144 from 160 leaves us 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.

The final outcome is 37456.388, with a leftover of 0.0016.
