We're dividing 81608520 by 812 
Our goal is to divide 81608520 by 812.

Step 1:
812 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 812

Moving on to step 2:
812 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 812

Let's proceed to step 3:
The number 812 fits into 816 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 812 from 816, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 812

Going ahead to step 4:
When dividing 40 by 812, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 812

Step 5:
When dividing 408 by 812, we get 0 with a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 408 and we're left with 408.
Append the next digit (5) from the dividend to 408 and continue with: 4085 / 812

Going ahead to step 6:
4085 divided by 812 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1005.0
If we subtract 4060 from 4085, we get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 812

Advancing to step 7:
812 can be fit into 252 0 times, resulting in a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 10050.0
Deduct 0 from 252 and we're left with 252.
Grab the next digit (0) from the dividend, add it to 252, then carry on: 2520 / 812

Going ahead to step 8:
2520 divided by 812 is 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 100503.0
If we take 2436 away from 2520, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
840 divided by 812 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 100503.1
The remainder is 28 after subtracting 812 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
812 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 100503.1
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
2800 divided by 812 is 3 with a remainder of 364.
The number 3 becomes the next digit in our result. 
Result so far: 100503.103
Subtracting 2436 from 2800 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 12:
If we divide 3640 by 812, we get 4 and a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 100503.1034
Deduct 3248 from 3640 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 13:
The number 812 fits into 3920 4 times, leaving a remainder of 672.
Write down 4 as next digit of the result. 
Result so far: 100503.10344
Deduct 3248 from 3920 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.

The quotient of the division is 100503.10344, and the remainder is 0.000672.
