We look at the division of 17850240 by 816 
Let's see how many times 816 fits into 17850240.

Let's proceed to step 1:
816 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 816

Let's proceed to step 2:
When dividing 17 by 816, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 816

Let's proceed to step 3:
When dividing 178 by 816, we get 0 with a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 178 and we're left with 178.
Append the next digit (5) from the dividend to 178 and continue with: 1785 / 816

Let's proceed to step 4:
1785 divided by 816 is 2 with a remainder of 153.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1632 from 1785 to get 153.
Include the next digit (0) from the dividend after 153, then repeat: 1530 / 816

Going ahead to step 5:
1530 divided by 816 is 1 with a remainder of 714.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 816 from 1530, we get 714.
Include the next digit (2) from the dividend after 714, then repeat: 7142 / 816

Going ahead to step 6:
7142 divided by 816 is 8 with a remainder of 614.
Write down 8 as next digit of the result. 
Result so far: 218.0
Subtract 6528 from 7142 to get 614.
Fetch the next digit (4) from the dividend, attach it to 614 and continue: 6144 / 816

Step 7:
816 can be fit into 6144 7 times, resulting in a remainder of 432.
Put 7 as the next digit of the answer. 
Result so far: 2187.0
If we take 5712 away from 6144, we end up with 432.
Grab the next digit (0) from the dividend, add it to 432, then carry on: 4320 / 816

On to step 8:
The number 816 fits into 4320 5 times, leaving a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 21875.0
If we take 4080 away from 4320, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 9:
2400 divided by 816 is 2 with a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 21875.2
Subtracting 1632 from 2400 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 10:
816 can be fit into 7680 9 times, resulting in a remainder of 336.
Put 9 as the next digit of the answer. 
Result so far: 21875.29
Deduct 7344 from 7680 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 11:
The number 816 fits into 3360 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 21875.294
Subtracting 3264 from 3360 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
The number 816 fits into 960 1 times, leaving a remainder of 144.
The next digit of our result is 1. 
Result so far: 21875.2941
Deduct 816 from 960 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 13:
816 can be fit into 1440 1 times, resulting in a remainder of 624.
Write down 1 as next digit of the result. 
Result so far: 21875.29411
If we take 816 away from 1440, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Our division results in 21875.29411 with a remaining 0.000624.
