We divide 937285 by 90
The aim is to understand the frequency of 90 in 937285.

Moving on to step 1:
90 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 90

Advancing to step 2:
When dividing 93 by 90, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 90 away from 93, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 90

Moving on to step 3:
If we divide 37 by 90, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 37, we end up with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 90

Advancing to step 4:
90 can be fit into 372 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 12 after subtracting 360 from 372.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 90

Let's proceed to step 5:
When dividing 128 by 90, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1041.0
The remainder is 38 after subtracting 90 from 128.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 90

Step 6:
385 divided by 90 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 10414.0
If we take 360 away from 385, we end up 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.

Moving on to step 7:
If we divide 250 by 90, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 10414.2
The remainder is 70 after subtracting 180 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 10414.27
If we subtract 630 from 700, we 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.

Going ahead to step 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 10414.277
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 10414.277, and the remainder is 0.007.
