We're dividing 73765699 by 256 
The aim is to understand the frequency of 256 in 73765699.

Let's proceed to step 1:
7 divided by 256 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 256

On to step 2:
The number 256 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 256

Let's proceed to step 3:
737 divided by 256 is 2 with a remainder of 225.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 512 from 737, we get 225.
Include the next digit (6) from the dividend after 225, then repeat: 2256 / 256

Let's proceed to step 4:
If we divide 2256 by 256, we get 8 and a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 208 after subtracting 2048 from 2256.
Include the next digit (5) from the dividend after 208, then repeat: 2085 / 256

Going ahead to step 5:
If we divide 2085 by 256, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
Subtracting 2048 from 2085 leaves us with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 256

Advancing to step 6:
When dividing 376 by 256, we get 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 2881.0
If we subtract 256 from 376, we get 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 256

Advancing to step 7:
If we divide 1209 by 256, we get 4 and a remainder of 185.
Use 4 as the next digit of our solution. 
Result so far: 28814.0
If we take 1024 away from 1209, we end up with 185.
Grab the next digit (9) from the dividend, add it to 185, then carry on: 1859 / 256

Advancing to step 8:
256 goes into 1859 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 288147.0
Subtracting 1792 from 1859 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
256 goes into 670 2 times with a remainder of 158.
The next digit of our result is 2. 
Result so far: 288147.2
The remainder is 158 after subtracting 512 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 10:
The number 256 fits into 1580 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 288147.26
Deduct 1536 from 1580 and we're left 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.

Advancing to step 11:
256 goes into 440 1 times with a remainder of 184.
The next digit of our result is 1. 
Result so far: 288147.261
If we take 256 away from 440, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
The number 256 fits into 1840 7 times, leaving a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 288147.2617
Subtracting 1792 from 1840 leaves us 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 13:
When dividing 480 by 256, we get 1 with a remainder of 224.
Write down 1 as next digit of the result. 
Result so far: 288147.26171
Subtract 256 from 480 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
256 goes into 2240 8 times with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 288147.261718
If we take 2048 away from 2240, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
When dividing 1920 by 256, we get 7 with a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 288147.2617187
If we take 1792 away from 1920, we end up 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.

Step 16:
If we divide 1280 by 256, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 288147.26171875
Deduct 1280 from 1280 and we're left 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 288147.26171875, with a leftover of 0.0.
