We look at the division of 690340 by 64 
The aim is to understand the frequency of 64 in 690340.

On to step 1:
64 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 64

Step 2:
If we divide 69 by 64, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 64 away from 69, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 64

Moving on to step 3:
64 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 50 to get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 64

Moving on to step 4:
64 goes into 503 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 448 from 503, we get 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 64

Moving on to step 5:
64 goes into 554 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 1078.0
If we take 512 away from 554, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 64

Advancing to step 6:
420 divided by 64 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 10786.0
Subtract 384 from 420 to get 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 7:
64 can be fit into 360 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 10786.5
The remainder is 40 after subtracting 320 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 64 fits into 400 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10786.56
Subtract 384 from 400 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.

On to step 9:
160 divided by 64 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 10786.562
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 64, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10786.5625
Subtract 320 from 320 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.

Step 11:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10786.5625
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.

Step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10786.5625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10786.5625 with a balance of 0.0.
