We look at the division of 81803876 by 981 
Let's see how many times 981 fits into 81803876.

Step 1:
When dividing 8 by 981, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 981

Step 2:
When dividing 81 by 981, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 981

Let's proceed to step 3:
981 goes into 818 0 times with a remainder of 818.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 818, we get 818.
Include the next digit (0) from the dividend after 818, then repeat: 8180 / 981

Step 4:
The number 981 fits into 8180 8 times, leaving a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7848 from 8180 leaves us with 332.
Append the next digit (3) from the dividend to 332 and continue with: 3323 / 981

Step 5:
When dividing 3323 by 981, we get 3 with a remainder of 380.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we subtract 2943 from 3323, we get 380.
Grab the next digit (8) from the dividend, add it to 380, then carry on: 3808 / 981

Moving on to step 6:
If we divide 3808 by 981, we get 3 and a remainder of 865.
The next digit of our result is 3. 
Result so far: 833.0
The remainder is 865 after subtracting 2943 from 3808.
Append the next digit (7) from the dividend to 865 and continue with: 8657 / 981

Going ahead to step 7:
The number 981 fits into 8657 8 times, leaving a remainder of 809.
Put 8 as the next digit of the answer. 
Result so far: 8338.0
If we take 7848 away from 8657, we end up with 809.
Fetch the next digit (6) from the dividend, attach it to 809 and continue: 8096 / 981

On to step 8:
981 can be fit into 8096 8 times, resulting in a remainder of 248.
The next digit of our result is 8. 
Result so far: 83388.0
If we subtract 7848 from 8096, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 9:
The number 981 fits into 2480 2 times, leaving a remainder of 518.
Put 2 as the next digit of the answer. 
Result so far: 83388.2
If we subtract 1962 from 2480, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 10:
981 can be fit into 5180 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 83388.25
If we take 4905 away from 5180, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
981 goes into 2750 2 times with a remainder of 788.
Use 2 as the next digit of our solution. 
Result so far: 83388.252
Subtract 1962 from 2750 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 12:
If we divide 7880 by 981, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 83388.2528
If we take 7848 away from 7880, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 981 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 83388.2528
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
981 can be fit into 3200 3 times, resulting in a remainder of 257.
Write down 3 as next digit of the result. 
Result so far: 83388.252803
The remainder is 257 after subtracting 2943 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 15:
981 goes into 2570 2 times with a remainder of 608.
Record the quotient 2 as the next digit in the result. 
Result so far: 83388.2528032
Subtract 1962 from 2570 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 16:
6080 divided by 981 is 6 with a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 83388.25280326
Subtract 5886 from 6080 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

In conclusion, the division gives 83388.25280326 with a balance of 1.94e-07.
