38128749 ÷ 256 
The aim is to understand the frequency of 256 in 38128749.

On to step 1:
If we divide 3 by 256, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
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 / 256

Advancing to step 2:
256 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 256

Let's proceed to step 3:
256 can be fit into 381 1 times, resulting in a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 256 from 381 to get 125.
Bring next digit (2) of the dividend behind the 125 and repeat the process: 1252 / 256

Let's proceed to step 4:
256 can be fit into 1252 4 times, resulting in a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1024 from 1252, we get 228.
Grab the next digit (8) from the dividend, add it to 228, then carry on: 2288 / 256

On to step 5:
When dividing 2288 by 256, we get 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Deduct 2048 from 2288 and we're left with 240.
Bring next digit (7) of the dividend behind the 240 and repeat the process: 2407 / 256

On to step 6:
The number 256 fits into 2407 9 times, leaving a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 1489.0
Deduct 2304 from 2407 and we're left with 103.
Fetch the next digit (4) from the dividend, attach it to 103 and continue: 1034 / 256

Step 7:
If we divide 1034 by 256, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14894.0
If we subtract 1024 from 1034, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 256

Moving on to step 8:
If we divide 109 by 256, we get 0 and a remainder of 109.
Put 0 as the next digit of the answer. 
Result so far: 148940.0
If we take 0 away from 109, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
256 can be fit into 1090 4 times, resulting in a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 148940.4
If we take 1024 away from 1090, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
256 can be fit into 660 2 times, resulting in a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 148940.42
If we take 512 away from 660, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
256 can be fit into 1480 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 148940.425
If we take 1280 away from 1480, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
When dividing 2000 by 256, we get 7 with a remainder of 208.
Use 7 as the next digit of our solution. 
Result so far: 148940.4257
Subtract 1792 from 2000 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 13:
If we divide 2080 by 256, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 148940.42578
If we take 2048 away from 2080, 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.

On to step 14:
256 goes into 320 1 times with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 148940.425781
If we subtract 256 from 320, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
If we divide 640 by 256, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 148940.4257812
Subtracting 512 from 640 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
256 goes into 1280 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 148940.42578125
If we take 1280 away from 1280, 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 final outcome is 148940.42578125, with a leftover of 0.0.
