982317 ÷ 21 
The aim is to understand the frequency of 21 in 982317.

Advancing to step 1:
9 divided by 21 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 21

Moving on to step 2:
98 divided by 21 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 84 from 98, we get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 21

Let's proceed to step 3:
21 goes into 142 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 126 from 142 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 21

Moving on to step 4:
21 goes into 163 7 times with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 467.0
Deduct 147 from 163 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 21

Going ahead to step 5:
21 goes into 161 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 4677.0
Subtracting 147 from 161 leaves us with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 21

Step 6:
When dividing 147 by 21, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 46777.0
Subtract 147 from 147 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 46777.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 21 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 46777.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 46777.0 and a remainder of 0.0.
