874421 ÷ 64 
The aim is to understand the frequency of 64 in 874421.

On to step 1:
64 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 64

Going ahead to step 2:
64 can be fit into 87 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we take 64 away from 87, we end up with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 64

Let's proceed to step 3:
When dividing 234 by 64, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 192 from 234, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 64

Going ahead to step 4:
64 can be fit into 424 6 times, resulting in a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtract 384 from 424 to get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 64

Going ahead to step 5:
64 goes into 402 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 1366.0
If we take 384 away from 402, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 64

Going ahead to step 6:
The number 64 fits into 181 2 times, leaving a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 13662.0
If we take 128 away from 181, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
If we divide 530 by 64, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 13662.8
Subtract 512 from 530 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 64, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 13662.82
The remainder is 52 after subtracting 128 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 64, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 13662.828
If we take 512 away from 520, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 64 fits into 80 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 13662.8281
If we take 64 away from 80, 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.

Advancing to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 13662.82812
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 12:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13662.828125
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.

Going ahead to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13662.828125
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.

Let's proceed to step 14:
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: 13662.828125
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.

The final result is 13662.828125 with a remainder of 0.0.
