We're dividing 148170 by 66 
We want to figure out the number of times 148170 can be divided by 66.

Step 1:
The number 66 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.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 66

Moving on to step 2:
14 divided by 66 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 66

Moving on to step 3:
The number 66 fits into 148 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 132 from 148 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 66

Going ahead to step 4:
The number 66 fits into 161 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 132 away from 161, we end up with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 66

Going ahead to step 5:
If we divide 297 by 66, we get 4 and a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtract 264 from 297 to get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 66

On to step 6:
66 can be fit into 330 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2245.0
Subtract 330 from 330 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.

On to step 7:
66 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2245.0
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.

Going ahead to step 8:
0 divided by 66 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2245.0
If we subtract 0 from 0, we 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.

The final outcome is 2245.0, with a leftover of 0.0.
