We look at the division of 369173 by 64 
The aim is to understand the frequency of 64 in 369173.

Step 1:
The number 64 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 64

Step 2:
64 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 64

Moving on to step 3:
If we divide 369 by 64, we get 5 and a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 320 from 369 and we're left with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 64

On to step 4:
64 goes into 491 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 448 from 491 leaves us with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 64

Advancing to step 5:
The number 64 fits into 437 6 times, leaving a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 576.0
Subtract 384 from 437 to get 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 64

Going ahead to step 6:
64 can be fit into 533 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 5768.0
The remainder is 21 after subtracting 512 from 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
64 goes into 210 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 5768.3
Subtracting 192 from 210 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
64 can be fit into 180 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 5768.32
If we subtract 128 from 180, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 64 fits into 520 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 5768.328
Subtracting 512 from 520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
64 goes into 80 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 5768.3281
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 5768.32812
If we take 128 away from 160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5768.328125
If we subtract 320 from 320, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5768.328125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5768.328125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5768.328125 with a remaining 0.0.
