We look at the division of 535883 by 69 
The aim is to understand the frequency of 69 in 535883.

On to step 1:
69 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 69

Let's proceed to step 2:
If we divide 53 by 69, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 69

Going ahead to step 3:
When dividing 535 by 69, we get 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 483 from 535 leaves us with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 69

Let's proceed to step 4:
528 divided by 69 is 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 483 from 528 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 69

Let's proceed to step 5:
The number 69 fits into 458 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 776.0
Subtracting 414 from 458 leaves us with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 69

Step 6:
69 goes into 443 6 times with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 7766.0
If we subtract 414 from 443, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
69 can be fit into 290 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 7766.4
Subtracting 276 from 290 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.

Advancing to step 8:
When dividing 140 by 69, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 7766.42
Deduct 138 from 140 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.

Moving on to step 9:
20 divided by 69 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7766.42
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.

On to step 10:
The number 69 fits into 200 2 times, leaving a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 7766.4202
Subtracting 138 from 200 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
If we divide 620 by 69, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 7766.42028
The remainder is 68 after subtracting 552 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
When dividing 680 by 69, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 7766.420289
If we take 621 away from 680, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
The number 69 fits into 590 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 7766.4202898
Subtracting 552 from 590 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.

Advancing to step 14:
When dividing 380 by 69, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 7766.42028985
The remainder is 35 after subtracting 345 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 7766.42028985 with a balance of 3.5e-08.
