408172 ÷ 64 
The aim is to understand the frequency of 64 in 408172.

Moving on to step 1:
4 divided by 64 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 64

Advancing to step 2:
64 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 64

On to step 3:
64 goes into 408 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 24 after subtracting 384 from 408.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 64

Going ahead to step 4:
If we divide 241 by 64, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we subtract 192 from 241, we get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 64

On to step 5:
If we divide 497 by 64, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 637.0
If we take 448 away from 497, we end up with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 64

Advancing to step 6:
When dividing 492 by 64, we get 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 6377.0
If we take 448 away from 492, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
64 goes into 440 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 6377.6
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 64, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 6377.68
If we take 512 away from 560, we end up 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 9:
480 divided by 64 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 6377.687
Subtracting 448 from 480 leaves us 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.

Advancing to step 10:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6377.6875
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.

Going ahead to step 11:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6377.6875
Subtracting 0 from 0 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.

Let's proceed to step 12:
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: 6377.6875
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.

The final outcome is 6377.6875, with a leftover of 0.0.
