615607 ÷ 64 
The aim is to understand the frequency of 64 in 615607.

On to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 64

Step 2:
When dividing 61 by 64, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 64

On to step 3:
64 goes into 615 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 576 away from 615, we end up with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 64

Going ahead to step 4:
When dividing 396 by 64, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 12 after subtracting 384 from 396.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 64

On to step 5:
When dividing 120 by 64, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 961.0
If we take 64 away from 120, we end up with 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 64

Advancing to step 6:
When dividing 567 by 64, we get 8 with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 9618.0
If we subtract 512 from 567, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
550 divided by 64 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 9618.8
Subtracting 512 from 550 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
64 goes into 380 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9618.85
If we take 320 away from 380, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 64 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 9618.859
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 64 fits into 240 3 times, leaving a remainder of 48.
The next digit of our result is 3. 
Result so far: 9618.8593
Subtracting 192 from 240 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 64 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 9618.85937
The remainder is 32 after subtracting 448 from 480.
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 12:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9618.859375
Subtracting 320 from 320 leaves us 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:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9618.859375
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.

Advancing to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9618.859375
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.

In conclusion, the division gives 9618.859375 with a balance of 0.0.
