94430 ÷ 21 
The aim is to understand the frequency of 21 in 94430.

Advancing to step 1:
21 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Going ahead to step 2:
When dividing 94 by 21, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 84 from 94 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 21

Going ahead to step 3:
21 can be fit into 104 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 84 from 104 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 21

Let's proceed to step 4:
21 can be fit into 203 9 times, resulting in a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
Subtracting 189 from 203 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

Going ahead to step 5:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 4496.0
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 6:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4496.6
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4496.66
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 4496.66 and a remainder of 0.014.
