Let's divide 128128 by 90
We want to figure out the number of times 128128 can be divided by 90.

Moving on to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 90

Going ahead to step 2:
When dividing 12 by 90, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 90

Moving on to step 3:
90 goes into 128 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 38 after subtracting 90 from 128.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 90

Advancing to step 4:
381 divided by 90 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 360 from 381 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 90

On to step 5:
If we divide 212 by 90, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 142.0
Subtract 180 from 212 to get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 90

Let's proceed to step 6:
90 goes into 328 3 times with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 1423.0
Subtract 270 from 328 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
90 can be fit into 580 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 1423.6
If we subtract 540 from 580, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 90 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1423.64
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1423.644
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1423.644 with a remainder of 0.004.
