We're dividing 846181 by 45 
Our goal is to divide 846181 by 45.

Let's proceed to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 45

Advancing to step 2:
84 divided by 45 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 84, we get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 45

Moving on to step 3:
If we divide 396 by 45, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 360 from 396 to get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 45

Going ahead to step 4:
When dividing 361 by 45, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 188.0
Subtract 360 from 361 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 45

On to step 5:
When dividing 18 by 45, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 1880.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 45

Moving on to step 6:
If we divide 181 by 45, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 18804.0
Deduct 180 from 181 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 45 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18804.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 18804.02
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 18804.022
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 18804.022, with a leftover of 0.001.
