We look at the division of 614644 by 64 
The aim is to understand the frequency of 64 in 614644.

Advancing to step 1:
64 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 64

Step 2:
When dividing 61 by 64, we get 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 64

Moving on to step 3:
64 can be fit into 614 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 38 after subtracting 576 from 614.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 64

Advancing to step 4:
The number 64 fits into 386 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtracting 384 from 386 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 64

Going ahead to step 5:
When dividing 24 by 64, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 960.0
Subtracting 0 from 24 leaves us with 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 64

Step 6:
244 divided by 64 is 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 9603.0
Subtracting 192 from 244 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
If we divide 520 by 64, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 9603.8
Subtract 512 from 520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 64, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 9603.81
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
160 divided by 64 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 9603.812
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9603.8125
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.

Advancing to step 11:
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: 9603.8125
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 12:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9603.8125
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.

The quotient of the division is 9603.8125, and the remainder is 0.0.
