Let's divide 146190 by 9
We're looking to find how many times 9 goes into 146190.

Step 1:
If we divide 1 by 9, 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.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 9

Moving on to step 2:
The number 9 fits into 14 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 9 from 14 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 9

Moving on to step 3:
9 goes into 56 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 54 away from 56, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 9

On to step 4:
The number 9 fits into 21 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 162.0
If we take 18 away from 21, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 9

Moving on to step 5:
9 can be fit into 39 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1624.0
Deduct 36 from 39 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Advancing to step 6:
When dividing 30 by 9, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 16243.0
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 16243.3
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 16243.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 16243.33 with a remainder of 0.003.
