85624458 ÷ 255 
Our goal is to divide 85624458 by 255.

Advancing to step 1:
The number 255 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 255

Advancing to step 2:
The number 255 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 255

Moving on to step 3:
255 can be fit into 856 3 times, resulting in a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 765 from 856 to get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 255

Let's proceed to step 4:
912 divided by 255 is 3 with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 147 after subtracting 765 from 912.
Append the next digit (4) from the dividend to 147 and continue with: 1474 / 255

Advancing to step 5:
If we divide 1474 by 255, we get 5 and a remainder of 199.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
If we take 1275 away from 1474, we end up with 199.
Append the next digit (4) from the dividend to 199 and continue with: 1994 / 255

Let's proceed to step 6:
255 goes into 1994 7 times with a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 3357.0
Subtracting 1785 from 1994 leaves us with 209.
Include the next digit (5) from the dividend after 209, then repeat: 2095 / 255

Let's proceed to step 7:
255 goes into 2095 8 times with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 33578.0
Subtracting 2040 from 2095 leaves us with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 255

Advancing to step 8:
255 goes into 558 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 335782.0
Subtract 510 from 558 to get 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:
255 can be fit into 480 1 times, resulting in a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 335782.1
Subtract 255 from 480 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 10:
When dividing 2250 by 255, we get 8 with a remainder of 210.
Record the quotient 8 as the next digit in the result. 
Result so far: 335782.18
Subtract 2040 from 2250 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 11:
The number 255 fits into 2100 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 335782.188
Subtracting 2040 from 2100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 335782.188, with a leftover of 0.006.
