We look at the division of 551670 by 30 
We want to figure out the number of times 551670 can be divided by 30.

Step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 30

Step 2:
30 goes into 55 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 25 after subtracting 30 from 55.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 30

Moving on to step 3:
When dividing 251 by 30, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 240 away from 251, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 30

Step 4:
116 divided by 30 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Deduct 90 from 116 and we're left with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 30

Advancing to step 5:
The number 30 fits into 267 8 times, leaving a remainder of 27.
The next digit of our result is 8. 
Result so far: 1838.0
Deduct 240 from 267 and we're left with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 30

Going ahead to step 6:
30 can be fit into 270 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 18389.0
The remainder is 0 after subtracting 270 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18389.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18389.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 18389.0 with a remaining 0.0.
