Let's divide 16351691 by 812
Let's see how many times 812 fits into 16351691.

Moving on to step 1:
1 divided by 812 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 812

Moving on to step 2:
812 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 812

Step 3:
The number 812 fits into 163 0 times, leaving a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 163, we get 163.
Append the next digit (5) from the dividend to 163 and continue with: 1635 / 812

Advancing to step 4:
The number 812 fits into 1635 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1624 from 1635 and we're left with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 812

Going ahead to step 5:
When dividing 111 by 812, we get 0 with a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 111 to get 111.
Include the next digit (6) from the dividend after 111, then repeat: 1116 / 812

Step 6:
The number 812 fits into 1116 1 times, leaving a remainder of 304.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
If we take 812 away from 1116, we end up with 304.
Fetch the next digit (9) from the dividend, attach it to 304 and continue: 3049 / 812

Advancing to step 7:
If we divide 3049 by 812, we get 3 and a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 2013.0
Deduct 2436 from 3049 and we're left with 613.
Fetch the next digit (1) from the dividend, attach it to 613 and continue: 6131 / 812

Let's proceed to step 8:
812 goes into 6131 7 times with a remainder of 447.
Write down 7 as next digit of the result. 
Result so far: 20137.0
If we take 5684 away from 6131, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 9:
When dividing 4470 by 812, we get 5 with a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 20137.5
Subtract 4060 from 4470 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
If we divide 4100 by 812, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 20137.55
Subtract 4060 from 4100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 20137.55 with a remainder of 0.04.
