42673693 divided by 255 
The aim is to understand the frequency of 255 in 42673693.

On to step 1:
If we divide 4 by 255, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 255

Let's proceed to step 2:
If we divide 42 by 255, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 255

Step 3:
426 divided by 255 is 1 with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 255 from 426 to get 171.
Grab the next digit (7) from the dividend, add it to 171, then carry on: 1717 / 255

Step 4:
If we divide 1717 by 255, we get 6 and a remainder of 187.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 1530 from 1717 to get 187.
Fetch the next digit (3) from the dividend, attach it to 187 and continue: 1873 / 255

Step 5:
255 can be fit into 1873 7 times, resulting in a remainder of 88.
The next digit of our result is 7. 
Result so far: 167.0
Subtract 1785 from 1873 to get 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 255

Moving on to step 6:
When dividing 886 by 255, we get 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 1673.0
If we take 765 away from 886, we end up with 121.
Include the next digit (9) from the dividend after 121, then repeat: 1219 / 255

Advancing to step 7:
1219 divided by 255 is 4 with a remainder of 199.
The next digit of our result is 4. 
Result so far: 16734.0
Subtract 1020 from 1219 to get 199.
Fetch the next digit (3) from the dividend, attach it to 199 and continue: 1993 / 255

Moving on to step 8:
The number 255 fits into 1993 7 times, leaving a remainder of 208.
The number 7 becomes the next digit in our result. 
Result so far: 167347.0
The remainder is 208 after subtracting 1785 from 1993.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 9:
2080 divided by 255 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 167347.8
The remainder is 40 after subtracting 2040 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 255, we get 1 and a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 167347.81
If we subtract 255 from 400, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 11:
1450 divided by 255 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 167347.815
Subtract 1275 from 1450 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 12:
255 goes into 1750 6 times with a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 167347.8156
If we take 1530 away from 1750, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
2200 divided by 255 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 167347.81568
If we take 2040 away from 2200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
The number 255 fits into 1600 6 times, leaving a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 167347.815686
If we subtract 1530 from 1600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
When dividing 700 by 255, we get 2 with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 167347.8156862
Subtract 510 from 700 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 16:
255 goes into 1900 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 167347.81568627
Subtracting 1785 from 1900 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The quotient of the division is 167347.81568627, and the remainder is 1.15e-07.
