657645 divided by 69 
The aim is to understand the frequency of 69 in 657645.

Moving on to step 1:
When dividing 6 by 69, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 69

Moving on to step 2:
If we divide 65 by 69, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 69

Advancing to step 3:
When dividing 657 by 69, we get 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 621 away from 657, we end up with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 69

Step 4:
When dividing 366 by 69, we get 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtracting 345 from 366 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 69

Moving on to step 5:
The number 69 fits into 214 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 953.0
Subtract 207 from 214 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 69

Going ahead to step 6:
69 goes into 75 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 9531.0
If we take 69 away from 75, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 69 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 9531.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
If we divide 600 by 69, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 9531.08
If we take 552 away from 600, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
480 divided by 69 is 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 9531.086
Deduct 414 from 480 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9531.0869
Deduct 621 from 660 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 69 fits into 390 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9531.08695
Subtract 345 from 390 to 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.

Let's proceed to step 12:
69 can be fit into 450 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 9531.086956
Subtracting 414 from 450 leaves us 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.

Going ahead to step 13:
69 goes into 360 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9531.0869565
Subtract 345 from 360 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
69 can be fit into 150 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 9531.08695652
If we subtract 138 from 150, we 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.

Our division results in 9531.08695652 with a remaining 1.2e-08.
