We look at the division of 81811722 by 816 
We're looking to find how many times 816 goes into 81811722.

Going ahead to step 1:
If we divide 8 by 816, we get 0 and 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 / 816

Advancing to step 2:
81 divided by 816 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 816

Advancing to step 3:
When dividing 818 by 816, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 816 from 818 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 816

Moving on to step 4:
21 divided by 816 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 816

On to step 5:
211 divided by 816 is 0 with a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 211 leaves us with 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 816

Let's proceed to step 6:
816 goes into 2117 2 times with a remainder of 485.
The number 2 becomes the next digit in our result. 
Result so far: 1002.0
Subtracting 1632 from 2117 leaves us with 485.
Bring next digit (2) of the dividend behind the 485 and repeat the process: 4852 / 816

Advancing to step 7:
If we divide 4852 by 816, we get 5 and a remainder of 772.
Put 5 as the next digit of the answer. 
Result so far: 10025.0
Subtract 4080 from 4852 to get 772.
Append the next digit (2) from the dividend to 772 and continue with: 7722 / 816

Advancing to step 8:
816 can be fit into 7722 9 times, resulting in a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 100259.0
The remainder is 378 after subtracting 7344 from 7722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 9:
If we divide 3780 by 816, we get 4 and a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 100259.4
Subtract 3264 from 3780 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 10:
The number 816 fits into 5160 6 times, leaving a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 100259.46
Deduct 4896 from 5160 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 11:
2640 divided by 816 is 3 with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 100259.463
Subtract 2448 from 2640 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 12:
1920 divided by 816 is 2 with a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 100259.4632
The remainder is 288 after subtracting 1632 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
The number 816 fits into 2880 3 times, leaving a remainder of 432.
The number 3 becomes the next digit in our result. 
Result so far: 100259.46323
Subtracting 2448 from 2880 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 14:
When dividing 4320 by 816, we get 5 with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 100259.463235
If we subtract 4080 from 4320, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
816 goes into 2400 2 times with a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 100259.4632352
Subtract 1632 from 2400 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 16:
816 goes into 7680 9 times with a remainder of 336.
Record the quotient 9 as the next digit in the result. 
Result so far: 100259.46323529
The remainder is 336 after subtracting 7344 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The quotient of the division is 100259.46323529, and the remainder is 3.36e-07.
