We look at the division of 669477 by 69 
The aim is to understand the frequency of 69 in 669477.

Advancing to 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
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 69

Let's proceed to step 2:
If we divide 66 by 69, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 69

Going ahead to step 3:
69 goes into 669 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 621 from 669 and we're left with 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 69

Let's proceed to step 4:
When dividing 484 by 69, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we take 483 away from 484, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 69

Advancing to step 5:
The number 69 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 970.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 69

Moving on to step 6:
69 goes into 177 2 times with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 9702.0
If we subtract 138 from 177, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
When dividing 390 by 69, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9702.5
If we subtract 345 from 390, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
When dividing 450 by 69, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 9702.56
Deduct 414 from 450 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
69 goes into 360 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9702.565
Subtracting 345 from 360 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 69 fits into 150 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 9702.5652
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 69, we get 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 9702.56521
If we take 69 away from 120, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
When dividing 510 by 69, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 9702.565217
Subtract 483 from 510 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
69 can be fit into 270 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 9702.5652173
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 14:
The number 69 fits into 630 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9702.56521739
Subtracting 621 from 630 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 9702.56521739 with a balance of 9e-09.
