We look at the division of 686944 by 69 
The aim is to understand the frequency of 69 in 686944.

Step 1:
The number 69 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 69

Advancing to step 2:
69 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 69

Going ahead to step 3:
When dividing 686 by 69, we get 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 621 from 686, we get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 69

Moving on to step 4:
When dividing 659 by 69, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 621 from 659, we get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 69

Let's proceed to step 5:
If we divide 384 by 69, we get 5 and a remainder of 39.
The next digit of our result is 5. 
Result so far: 995.0
Subtracting 345 from 384 leaves us with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 69

Let's proceed to step 6:
69 goes into 394 5 times with a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 9955.0
If we take 345 away from 394, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
The number 69 fits into 490 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 9955.7
If we subtract 483 from 490, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 69, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 9955.71
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 69 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9955.71
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 69 fits into 100 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 9955.7101
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
69 can be fit into 310 4 times, resulting in a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 9955.71014
If we subtract 276 from 310, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
If we divide 340 by 69, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9955.710144
Subtracting 276 from 340 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 9955.710144 with a balance of 6.4e-06.
