Let's divide 148648 by 90
We want to figure out the number of times 148648 can be divided by 90.

Step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

Let's proceed to step 2:
90 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 90

Moving on to step 3:
When dividing 148 by 90, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 90 from 148 and we're left with 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 90

On to step 4:
If we divide 586 by 90, we get 6 and a remainder of 46.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 540 from 586 leaves us with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 90

Let's proceed to step 5:
464 divided by 90 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 450 away from 464, we end up with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 90

On to step 6:
If we divide 148 by 90, we get 1 and a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1651.0
If we take 90 away from 148, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
If we divide 580 by 90, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 1651.6
If we take 540 away from 580, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1651.64
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1651.644
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 1651.644 with a remaining 0.004.
