148223 ÷ 90 
We want to figure out the number of times 148223 can be divided by 90.

Going ahead to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

Going ahead to step 2:
If we divide 14 by 90, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 90

Advancing to step 3:
90 goes into 148 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 90 away from 148, we end up with 58.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 90

Advancing to step 4:
When dividing 582 by 90, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 540 from 582 leaves us with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 90

On to step 5:
90 goes into 422 4 times with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Deduct 360 from 422 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 90

Going ahead to step 6:
623 divided by 90 is 6 with a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 1646.0
Subtracting 540 from 623 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
The number 90 fits into 830 9 times, leaving a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 1646.9
If we subtract 810 from 830, 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.

Let's proceed to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1646.92
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:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 1646.922
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 1646.922 with a remaining 0.002.
