We look at the division of 198171 by 30 
We want to figure out the number of times 198171 can be divided by 30.

Step 1:
If we divide 1 by 30, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 30

Let's proceed to step 2:
19 divided by 30 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 30

Going ahead to step 3:
30 can be fit into 198 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 180 from 198 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 30

Going ahead to step 4:
When dividing 181 by 30, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 1 after subtracting 180 from 181.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 30

Moving on to step 5:
30 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 660.0
If we take 0 away from 17, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 30

Moving on to step 6:
The number 30 fits into 171 5 times, leaving a remainder of 21.
The next digit of our result is 5. 
Result so far: 6605.0
Subtract 150 from 171 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 30, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 6605.7
If we take 210 away from 210, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6605.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6605.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6605.7, with a leftover of 0.0.
