We look at the division of 543785 by 69 
The aim is to understand the frequency of 69 in 543785.

Let's proceed to step 1:
If we divide 5 by 69, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 69

Advancing to step 2:
69 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 69

Going ahead to step 3:
543 divided by 69 is 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 483 from 543 and we're left with 60.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 69

On to step 4:
If we divide 607 by 69, we get 8 and a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 552 from 607 leaves us with 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 69

On to step 5:
69 goes into 558 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 788.0
Deduct 552 from 558 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 69

On to step 6:
The number 69 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 7880.0
Subtract 0 from 65 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
650 divided by 69 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 7880.9
Subtracting 621 from 650 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
The number 69 fits into 290 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 7880.94
If we subtract 276 from 290, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
69 can be fit into 140 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7880.942
Subtracting 138 from 140 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 10:
69 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7880.942
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
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: 7880.94202
Subtract 138 from 200 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
69 goes into 620 8 times with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 7880.942028
Subtract 552 from 620 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
The number 69 fits into 680 9 times, leaving a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 7880.9420289
Subtract 621 from 680 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
When dividing 590 by 69, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 7880.94202898
If we take 552 away from 590, we end up 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.

In conclusion, the division gives 7880.94202898 with a balance of 3.8e-08.
