994093 ÷ 90 
The aim is to understand the frequency of 90 in 994093.

Moving on to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 90

Moving on to step 2:
If we divide 99 by 90, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 90 from 99 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 90

Let's proceed to step 3:
90 goes into 94 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 90 from 94, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 90

Advancing to step 4:
If we divide 40 by 90, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 40 to get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 90

Advancing to step 5:
90 goes into 409 4 times with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 1104.0
The remainder is 49 after subtracting 360 from 409.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 90

Advancing to step 6:
493 divided by 90 is 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 11045.0
Subtracting 450 from 493 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
When dividing 430 by 90, we get 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 11045.4
The remainder is 70 after subtracting 360 from 430.
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 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 11045.47
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.

Moving on to step 9:
90 goes into 700 7 times with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 11045.477
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.

The final result is 11045.477 with a remainder of 0.007.
