We're dividing 283975 by 90 
We want to figure out the number of times 283975 can be divided by 90.

Let's proceed to step 1:
2 divided by 90 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 90

Let's proceed to step 2:
The number 90 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 90

Moving on to step 3:
If we divide 283 by 90, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 270 away from 283, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 90

Advancing to step 4:
The number 90 fits into 139 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 90 from 139, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 90

Going ahead to step 5:
90 goes into 497 5 times with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtract 450 from 497 to get 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 90

Let's proceed to step 6:
90 goes into 475 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3155.0
Subtracting 450 from 475 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
90 goes into 250 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 3155.2
Subtract 180 from 250 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 90 is 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 3155.27
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 3155.277
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3155.277 with a remainder of 0.007.
