We're dividing 878842 by 64 
The aim is to understand the frequency of 64 in 878842.

Going ahead to step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 64

Going ahead to step 2:
When dividing 87 by 64, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 23 after subtracting 64 from 87.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 64

Advancing to step 3:
64 goes into 238 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 192 from 238, we get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 64

Step 4:
468 divided by 64 is 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 137.0
The remainder is 20 after subtracting 448 from 468.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 64

Going ahead to step 5:
204 divided by 64 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1373.0
Deduct 192 from 204 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 64

Step 6:
If we divide 122 by 64, we get 1 and a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 13731.0
Subtracting 64 from 122 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
64 goes into 580 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 13731.9
If we take 576 away from 580, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 64, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13731.9
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

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: 13731.906
If we take 384 away from 400, we end up 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.

Moving on to step 10:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 13731.9062
If we subtract 128 from 160, we 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.

Advancing to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 13731.90625
The remainder is 0 after subtracting 320 from 320.
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:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 13731.90625
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.

Advancing to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 13731.90625
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 quotient of the division is 13731.90625, and the remainder is 0.0.
