Let's divide 166030 by 9
We want to figure out the number of times 166030 can be divided by 9.

Step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

Let's proceed to step 2:
The number 9 fits into 16 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 9 from 16 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 9

Going ahead to step 3:
When dividing 76 by 9, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 72 away from 76, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 9

Moving on to step 4:
When dividing 40 by 9, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 184.0
If we subtract 36 from 40, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Let's proceed to step 5:
If we divide 43 by 9, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 1844.0
Deduct 36 from 43 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 9

Moving on to step 6:
If we divide 70 by 9, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 18447.0
Subtract 63 from 70 to get 7.
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:
9 goes into 70 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 18447.7
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 9, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 18447.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 18447.77, and the remainder is 0.007.
