We look at the division of 497421 by 69 
The aim is to understand the frequency of 69 in 497421.

Going ahead to step 1:
If we divide 4 by 69, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 69

On to step 2:
49 divided by 69 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 69

Moving on to step 3:
When dividing 497 by 69, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 483 from 497 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 69

Going ahead to step 4:
If we divide 144 by 69, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 138 from 144, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 69

Going ahead to step 5:
The number 69 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 720.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 69

On to step 6:
69 can be fit into 621 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 7209.0
Subtracting 621 from 621 leaves us 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.

Let's proceed to step 7:
0 divided by 69 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7209.0
Subtract 0 from 0 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.

Let's proceed to step 8:
0 divided by 69 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7209.0
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.

The final result is 7209.0 with a remainder of 0.0.
