Let's divide 970214 by 21
The aim is to understand the frequency of 21 in 970214.

Let's proceed to step 1:
21 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 21

Step 2:
21 can be fit into 97 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 84 from 97, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 21

Let's proceed to step 3:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 126 from 130, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 21

Advancing to step 4:
21 can be fit into 42 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 462.0
Deduct 42 from 42 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 21

Advancing to step 5:
1 divided by 21 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 4620.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 21

Step 6:
21 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 46200.0
Subtract 0 from 14 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.
Put 6 as the next digit of the answer. 
Result so far: 46200.6
Subtracting 126 from 140 leaves us 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.

Moving on to step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 46200.66
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.

The final outcome is 46200.66, with a leftover of 0.014.
