We divide 686543 by 69
The aim is to understand the frequency of 69 in 686543.

Let's proceed to step 1:
6 divided by 69 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 69

Moving on to step 2:
69 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 69

Advancing to step 3:
When dividing 686 by 69, we get 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 621 from 686 leaves us with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 69

Going ahead to step 4:
When dividing 655 by 69, we get 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 621 away from 655, we end up with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 69

Let's proceed to step 5:
The number 69 fits into 344 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 994.0
Subtract 276 from 344 to get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 69

Going ahead to step 6:
683 divided by 69 is 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 9949.0
If we take 621 away from 683, we end up 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.

Going ahead to step 7:
69 goes into 620 8 times with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 9949.8
Subtracting 552 from 620 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
69 goes into 680 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 9949.89
Subtracting 621 from 680 leaves us 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.

Let's proceed to step 9:
590 divided by 69 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 9949.898
The remainder is 38 after subtracting 552 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
69 goes into 380 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9949.8985
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.

Step 11:
If we divide 350 by 69, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9949.89855
Deduct 345 from 350 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 9949.89855, with a leftover of 5e-06.
