We look at the division of 551981 by 30 
We want to divide 551981 by 30.

Advancing to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 30

Advancing to step 2:
55 divided by 30 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 30 from 55 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 30

Moving on to step 3:
The number 30 fits into 251 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 240 from 251 and we're left with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 30

On to step 4:
30 can be fit into 119 3 times, resulting in a remainder of 29.
The next digit of our result is 3. 
Result so far: 183.0
Deduct 90 from 119 and we're left with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 30

Going ahead to step 5:
If we divide 298 by 30, we get 9 and a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 1839.0
The remainder is 28 after subtracting 270 from 298.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 30

Moving on to step 6:
30 goes into 281 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 18399.0
Subtracting 270 from 281 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
30 goes into 110 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 18399.3
If we subtract 90 from 110, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 18399.36
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 18399.366
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 18399.366 with a remaining 0.002.
