90855 divided by 1 
We're looking to find how many times 1 goes into 90855.

Moving on to step 1:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 9 away from 9, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

On to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 0, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Advancing to step 3:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 908.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9085.0
Subtract 5 from 5 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Let's proceed to step 5:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 90855.0
Deduct 5 from 5 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.

Let's proceed to step 6:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90855.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 90855.0
Deduct 0 from 0 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 90855.0, with a leftover of 0.0.
