We're dividing 697490 by 22 
The aim is to understand the frequency of 22 in 697490.

Step 1:
When dividing 6 by 22, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 22

On to step 2:
If we divide 69 by 22, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 66 from 69 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 22

On to step 3:
If we divide 37 by 22, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 22 from 37 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 22

On to step 4:
22 goes into 154 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtracting 154 from 154 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 22

Going ahead to step 5:
If we divide 9 by 22, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 3170.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 22

Advancing to step 6:
When dividing 90 by 22, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 31704.0
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
22 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 31704.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 31704.09
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 22, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 31704.09
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
22 goes into 200 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 31704.0909
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 31704.0909
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 31704.090909
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
20 divided by 22 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 31704.090909
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
22 can be fit into 200 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 31704.09090909
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 31704.09090909 with a balance of 2e-09.
