We divide 845900 by 1
We're looking to find how many times 1 goes into 845900.

Advancing to step 1:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 4 from 4, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 3:
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: 845.0
If we subtract 5 from 5, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 4:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 8459.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Step 5:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 84590.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 845900.0
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.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 845900.0
Subtract 0 from 0 to 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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 845900.0
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.

In conclusion, the division gives 845900.0 with a balance of 0.0.
