102928 ÷ 90 
We want to divide 102928 by 90.

Let's proceed to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 90

Going ahead to step 2:
90 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 90

Going ahead to step 3:
If we divide 102 by 90, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 90 from 102 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 90

Going ahead to step 4:
90 can be fit into 129 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 90 away from 129, we end up with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 90

Let's proceed to step 5:
The number 90 fits into 392 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtract 360 from 392 to get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 90

Going ahead to step 6:
The number 90 fits into 328 3 times, leaving a remainder of 58.
The next digit of our result is 3. 
Result so far: 1143.0
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.

Step 7:
90 can be fit into 580 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1143.6
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:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1143.64
The remainder is 40 after subtracting 360 from 400.
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:
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: 1143.644
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.

The final result is 1143.644 with a remainder of 0.004.
