778922 ÷ 64 
The aim is to understand the frequency of 64 in 778922.

Advancing to step 1:
7 divided by 64 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 64

On to step 2:
64 can be fit into 77 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 64 from 77, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 64

Let's proceed to step 3:
If we divide 138 by 64, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 128 from 138 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 64

Let's proceed to step 4:
The number 64 fits into 109 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 121.0
Deduct 64 from 109 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 64

Step 5:
The number 64 fits into 452 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 1217.0
The remainder is 4 after subtracting 448 from 452.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 64

Step 6:
When dividing 42 by 64, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 12170.0
Deduct 0 from 42 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
When dividing 420 by 64, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 12170.6
If we subtract 384 from 420, we 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 8:
If we divide 360 by 64, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 12170.65
If we subtract 320 from 360, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 12170.656
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 64, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12170.6562
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.

Moving on to step 11:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12170.65625
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.

Advancing to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12170.65625
If we take 0 away from 0, we end up 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 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12170.65625
If we take 0 away from 0, we end up 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.

The final result is 12170.65625 with a remainder of 0.0.
