Let's divide 938063 by 90
The aim is to understand the frequency of 90 in 938063.

On to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 90

Going ahead to step 2:
93 divided by 90 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 90 from 93.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 90

Let's proceed to step 3:
90 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 90

On to step 4:
380 divided by 90 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we take 360 away from 380, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 90

On to step 5:
When dividing 206 by 90, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 1042.0
If we subtract 180 from 206, we get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 90

On to step 6:
The number 90 fits into 263 2 times, leaving a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 10422.0
If we subtract 180 from 263, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 7:
90 goes into 830 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 10422.9
Subtracting 810 from 830 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 10422.92
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 10422.922
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 10422.922, and the remainder is 0.002.
