38540868 ÷ 456 
The aim is to understand the frequency of 456 in 38540868.

Moving on to step 1:
When dividing 3 by 456, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 456

Let's proceed to step 2:
If we divide 38 by 456, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 456

Let's proceed to step 3:
456 goes into 385 0 times with a remainder of 385.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 385 and we're left with 385.
Bring next digit (4) of the dividend behind the 385 and repeat the process: 3854 / 456

Advancing to step 4:
The number 456 fits into 3854 8 times, leaving a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 206 after subtracting 3648 from 3854.
Take the next digit (0) from the dividend and append it to 206, then repeat: 2060 / 456

Going ahead to step 5:
2060 divided by 456 is 4 with a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 236 after subtracting 1824 from 2060.
Take the next digit (8) from the dividend and append it to 236, then repeat: 2368 / 456

Advancing to step 6:
If we divide 2368 by 456, we get 5 and a remainder of 88.
Write down 5 as next digit of the result. 
Result so far: 845.0
Subtracting 2280 from 2368 leaves us with 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 456

Going ahead to step 7:
456 goes into 886 1 times with a remainder of 430.
Put 1 as the next digit of the answer. 
Result so far: 8451.0
Subtracting 456 from 886 leaves us with 430.
Bring next digit (8) of the dividend behind the 430 and repeat the process: 4308 / 456

Moving on to step 8:
When dividing 4308 by 456, we get 9 with a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 84519.0
Deduct 4104 from 4308 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 9:
456 can be fit into 2040 4 times, resulting in a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 84519.4
If we subtract 1824 from 2040, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
456 goes into 2160 4 times with a remainder of 336.
The next digit of our result is 4. 
Result so far: 84519.44
If we take 1824 away from 2160, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 84519.44 with a remaining 0.336.
