Let's divide 863510 by 45
Our goal is to divide 863510 by 45.

Let's proceed to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 45

Step 2:
The number 45 fits into 86 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 86 leaves us with 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 45

Advancing to step 3:
413 divided by 45 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 405 from 413 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 45

Step 4:
45 can be fit into 85 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtract 45 from 85 to get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 45

Advancing to step 5:
401 divided by 45 is 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 1918.0
Deduct 360 from 401 and we're left with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 45

Let's proceed to step 6:
45 can be fit into 410 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 19189.0
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
45 goes into 50 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 19189.1
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 19189.11
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 19189.11 with a remaining 0.005.
