64169509 divided by 69 
The aim is to understand the frequency of 69 in 64169509.

Let's proceed to step 1:
69 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 69

Going ahead to step 2:
69 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 69

Let's proceed to step 3:
641 divided by 69 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 621 from 641 to get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 69

Moving on to step 4:
If we divide 206 by 69, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtract 138 from 206 to get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 69

Let's proceed to step 5:
The number 69 fits into 689 9 times, leaving a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 929.0
If we subtract 621 from 689, we get 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 69

Moving on to step 6:
685 divided by 69 is 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 9299.0
Deduct 621 from 685 and we're left with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 69

On to step 7:
69 goes into 640 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 92999.0
Deduct 621 from 640 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 69

Let's proceed to step 8:
199 divided by 69 is 2 with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 929992.0
Subtracting 138 from 199 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
610 divided by 69 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 929992.8
The remainder is 58 after subtracting 552 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
If we divide 580 by 69, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 929992.88
Subtracting 552 from 580 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 929992.88, and the remainder is 0.028.
