We're dividing 81856 by 45 
We're looking to find how many times 45 goes into 81856.

Going ahead to step 1:
45 can be fit into 8 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

Going ahead to step 2:
45 can be fit into 81 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 45 from 81, we get 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 45

Step 3:
368 divided by 45 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 360 from 368 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 45

Advancing to step 4:
85 divided by 45 is 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 181.0
If we subtract 45 from 85, we get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 45

Moving on to step 5:
When dividing 406 by 45, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1819.0
If we take 405 away from 406, we end up 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.

On to step 6:
10 divided by 45 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1819.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
45 goes into 100 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1819.02
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1819.022
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1819.022 with a remaining 0.001.
