124539 divided by 64 
The aim is to understand the frequency of 64 in 124539.

Going ahead to step 1:
64 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 64

Moving on to step 2:
64 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 64

Moving on to step 3:
The number 64 fits into 124 1 times, leaving a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 124 and we're left with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 64

On to step 4:
The number 64 fits into 605 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 576 from 605 and we're left with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 64

On to step 5:
The number 64 fits into 293 4 times, leaving a remainder of 37.
The next digit of our result is 4. 
Result so far: 194.0
Subtract 256 from 293 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 64

Step 6:
The number 64 fits into 379 5 times, leaving a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 1945.0
Subtract 320 from 379 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
If we divide 590 by 64, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 1945.9
The remainder is 14 after subtracting 576 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 64, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1945.92
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 64 is 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1945.921
The remainder is 56 after subtracting 64 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
64 goes into 560 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1945.9218
If we subtract 512 from 560, we get 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:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1945.92187
If we take 448 away from 480, 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.

Let's proceed to step 12:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1945.921875
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.

Going ahead to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1945.921875
If we subtract 0 from 0, 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.

On to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1945.921875
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.

The quotient of the division is 1945.921875, and the remainder is 0.0.
