94300 ÷ 90 
The aim is to understand the frequency of 90 in 94300.

On to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 90

Step 2:
The number 90 fits into 94 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 90 from 94, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 90

Step 3:
43 divided by 90 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 90

Going ahead to step 4:
When dividing 430 by 90, we get 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 360 from 430 and we're left with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 90

Moving on to step 5:
700 divided by 90 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1047.0
Subtract 630 from 700 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.

Moving on to step 6:
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: 1047.7
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.

Advancing to step 7:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1047.77
Deduct 630 from 700 and we're left 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 quotient of the division is 1047.77, and the remainder is 0.07.
