Let's divide 81389220 by 818
We want to divide 81389220 by 818.

Moving on to step 1:
818 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 818

On to step 2:
81 divided by 818 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 818

Advancing to step 3:
If we divide 813 by 818, we get 0 and a remainder of 813.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 813, we get 813.
Grab the next digit (8) from the dividend, add it to 813, then carry on: 8138 / 818

Moving on to step 4:
If we divide 8138 by 818, we get 9 and a remainder of 776.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7362 away from 8138, we end up with 776.
Fetch the next digit (9) from the dividend, attach it to 776 and continue: 7769 / 818

On to step 5:
If we divide 7769 by 818, we get 9 and a remainder of 407.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 7362 from 7769 to get 407.
Fetch the next digit (2) from the dividend, attach it to 407 and continue: 4072 / 818

Moving on to step 6:
818 goes into 4072 4 times with a remainder of 800.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
Subtract 3272 from 4072 to get 800.
Bring next digit (2) of the dividend behind the 800 and repeat the process: 8002 / 818

On to step 7:
When dividing 8002 by 818, we get 9 with a remainder of 640.
Use 9 as the next digit of our solution. 
Result so far: 9949.0
The remainder is 640 after subtracting 7362 from 8002.
Bring next digit (0) of the dividend behind the 640 and repeat the process: 6400 / 818

Going ahead to step 8:
818 goes into 6400 7 times with a remainder of 674.
The next digit of our result is 7. 
Result so far: 99497.0
If we take 5726 away from 6400, we end up with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Step 9:
If we divide 6740 by 818, we get 8 and a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 99497.8
The remainder is 196 after subtracting 6544 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
1960 divided by 818 is 2 with a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 99497.82
Subtracting 1636 from 1960 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 11:
818 can be fit into 3240 3 times, resulting in a remainder of 786.
Use 3 as the next digit of our solution. 
Result so far: 99497.823
If we take 2454 away from 3240, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Step 12:
818 can be fit into 7860 9 times, resulting in a remainder of 498.
Put 9 as the next digit of the answer. 
Result so far: 99497.8239
If we take 7362 away from 7860, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 13:
The number 818 fits into 4980 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 99497.82396
Subtract 4908 from 4980 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
When dividing 720 by 818, we get 0 with a remainder of 720.
The number 0 becomes the next digit in our result. 
Result so far: 99497.82396
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 15:
If we divide 7200 by 818, we get 8 and a remainder of 656.
The next digit of our result is 8. 
Result so far: 99497.8239608
If we subtract 6544 from 7200, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 16:
If we divide 6560 by 818, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 99497.82396088
Subtracting 6544 from 6560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 99497.82396088 with a remainder of 1.6e-08.
