We're dividing 973128 by 90 
We're looking to find how many times 90 goes into 973128.

Let's proceed to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 90

On to step 2:
97 divided by 90 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 90 from 97, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 90

On to step 3:
The number 90 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 73 to get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 90

Moving on to step 4:
90 can be fit into 731 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 720 from 731 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 90

Going ahead to step 5:
When dividing 112 by 90, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1081.0
Subtracting 90 from 112 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 90

Moving on to step 6:
When dividing 228 by 90, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10812.0
The remainder is 48 after subtracting 180 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 10812.5
The remainder is 30 after subtracting 450 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 90 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 10812.53
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
90 goes into 300 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 10812.533
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 10812.533 with a remainder of 0.003.
