508913 ÷ 69 
The aim is to understand the frequency of 69 in 508913.

Step 1:
5 divided by 69 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 69

Let's proceed to step 2:
69 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 69

Step 3:
If we divide 508 by 69, we get 7 and a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 483 from 508 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 69

Going ahead to step 4:
259 divided by 69 is 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 207 from 259 leaves us with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 69

Let's proceed to step 5:
The number 69 fits into 521 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 737.0
Deduct 483 from 521 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 69

On to step 6:
383 divided by 69 is 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 7375.0
Subtracting 345 from 383 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 69 fits into 380 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7375.5
Subtracting 345 from 380 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
69 can be fit into 350 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7375.55
Subtract 345 from 350 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 7375.55 and a remainder of 0.005.
