Let's divide 13528986 by 816
We want to divide 13528986 by 816.

Step 1:
The number 816 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 816

On to step 2:
When dividing 13 by 816, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 816

Going ahead to step 3:
The number 816 fits into 135 0 times, leaving a remainder of 135.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Append the next digit (2) from the dividend to 135 and continue with: 1352 / 816

Advancing to step 4:
When dividing 1352 by 816, we get 1 with a remainder of 536.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 816 away from 1352, we end up with 536.
Fetch the next digit (8) from the dividend, attach it to 536 and continue: 5368 / 816

Going ahead to step 5:
816 goes into 5368 6 times with a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 4896 from 5368 to get 472.
Append the next digit (9) from the dividend to 472 and continue with: 4729 / 816

On to step 6:
816 can be fit into 4729 5 times, resulting in a remainder of 649.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we subtract 4080 from 4729, we get 649.
Append the next digit (8) from the dividend to 649 and continue with: 6498 / 816

Going ahead to step 7:
816 can be fit into 6498 7 times, resulting in a remainder of 786.
Use 7 as the next digit of our solution. 
Result so far: 1657.0
Deduct 5712 from 6498 and we're left with 786.
Append the next digit (6) from the dividend to 786 and continue with: 7866 / 816

Going ahead to step 8:
816 goes into 7866 9 times with a remainder of 522.
The number 9 becomes the next digit in our result. 
Result so far: 16579.0
If we take 7344 away from 7866, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 9:
If we divide 5220 by 816, we get 6 and a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 16579.6
The remainder is 324 after subtracting 4896 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
3240 divided by 816 is 3 with a remainder of 792.
Write down 3 as next digit of the result. 
Result so far: 16579.63
Subtract 2448 from 3240 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 11:
The number 816 fits into 7920 9 times, leaving a remainder of 576.
Put 9 as the next digit of the answer. 
Result so far: 16579.639
Subtracting 7344 from 7920 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 12:
The number 816 fits into 5760 7 times, leaving a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 16579.6397
If we take 5712 away from 5760, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
816 can be fit into 480 0 times, resulting in a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 16579.6397
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
816 can be fit into 4800 5 times, resulting in a remainder of 720.
Record the quotient 5 as the next digit in the result. 
Result so far: 16579.639705
The remainder is 720 after subtracting 4080 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 15:
7200 divided by 816 is 8 with a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 16579.6397058
Deduct 6528 from 7200 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 16:
816 can be fit into 6720 8 times, resulting in a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 16579.63970588
If we take 6528 away from 6720, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 16579.63970588 with a remainder of 1.92e-07.
