We look at the division of 15474989 by 816 
Our goal is to divide 15474989 by 816.

On to step 1:
816 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 816

Let's proceed to step 2:
The number 816 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 816

Advancing to step 3:
154 divided by 816 is 0 with a remainder of 154.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Take the next digit (7) from the dividend and append it to 154, then repeat: 1547 / 816

On to step 4:
816 goes into 1547 1 times with a remainder of 731.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 816 from 1547 and we're left with 731.
Grab the next digit (4) from the dividend, add it to 731, then carry on: 7314 / 816

Moving on to step 5:
816 goes into 7314 8 times with a remainder of 786.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 786 after subtracting 6528 from 7314.
Include the next digit (9) from the dividend after 786, then repeat: 7869 / 816

Let's proceed to step 6:
7869 divided by 816 is 9 with a remainder of 525.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtracting 7344 from 7869 leaves us with 525.
Grab the next digit (8) from the dividend, add it to 525, then carry on: 5258 / 816

On to step 7:
When dividing 5258 by 816, we get 6 with a remainder of 362.
The number 6 becomes the next digit in our result. 
Result so far: 1896.0
If we subtract 4896 from 5258, we get 362.
Bring next digit (9) of the dividend behind the 362 and repeat the process: 3629 / 816

On to step 8:
816 can be fit into 3629 4 times, resulting in a remainder of 365.
Put 4 as the next digit of the answer. 
Result so far: 18964.0
Subtract 3264 from 3629 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
If we divide 3650 by 816, we get 4 and a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 18964.4
Deduct 3264 from 3650 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
3860 divided by 816 is 4 with a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 18964.44
The remainder is 596 after subtracting 3264 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Our division results in 18964.44 with a remaining 0.596.
