Let's divide 861544 by 45
We want to divide 861544 by 45.

Let's proceed to step 1:
45 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 45

On to step 2:
45 can be fit into 86 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 86 and we're left with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 45

Step 3:
When dividing 411 by 45, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 405 from 411, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 45

Advancing to step 4:
The number 45 fits into 65 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 191.0
Subtracting 45 from 65 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 45

Going ahead to step 5:
204 divided by 45 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1914.0
Deduct 180 from 204 and we're left with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 45

Let's proceed to step 6:
45 goes into 244 5 times with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 19145.0
Subtract 225 from 244 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
45 can be fit into 190 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 19145.4
If we subtract 180 from 190, we get 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 8:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 19145.42
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.

Moving on to step 9:
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: 19145.422
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.

Our division results in 19145.422 with a remaining 0.001.
