We look at the division of 81887301 by 721 
Let's see how many times 721 fits into 81887301.

Advancing to step 1:
If we divide 8 by 721, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 721

Moving on to step 2:
When dividing 81 by 721, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 721

Moving on to step 3:
When dividing 818 by 721, we get 1 with a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 721 from 818 and we're left with 97.
Take the next digit (8) from the dividend and append it to 97, then repeat: 978 / 721

Let's proceed to step 4:
721 can be fit into 978 1 times, resulting in a remainder of 257.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 721 from 978 leaves us with 257.
Bring next digit (7) of the dividend behind the 257 and repeat the process: 2577 / 721

Step 5:
2577 divided by 721 is 3 with a remainder of 414.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 2163 from 2577, we get 414.
Take the next digit (3) from the dividend and append it to 414, then repeat: 4143 / 721

Going ahead to step 6:
721 can be fit into 4143 5 times, resulting in a remainder of 538.
The next digit of our result is 5. 
Result so far: 1135.0
Deduct 3605 from 4143 and we're left with 538.
Grab the next digit (0) from the dividend, add it to 538, then carry on: 5380 / 721

Let's proceed to step 7:
If we divide 5380 by 721, we get 7 and a remainder of 333.
Record the quotient 7 as the next digit in the result. 
Result so far: 11357.0
If we subtract 5047 from 5380, we get 333.
Fetch the next digit (1) from the dividend, attach it to 333 and continue: 3331 / 721

Going ahead to step 8:
721 goes into 3331 4 times with a remainder of 447.
The number 4 becomes the next digit in our result. 
Result so far: 113574.0
Deduct 2884 from 3331 and we're left 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.

Moving on to step 9:
The number 721 fits into 4470 6 times, leaving a remainder of 144.
The next digit of our result is 6. 
Result so far: 113574.6
The remainder is 144 after subtracting 4326 from 4470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 10:
When dividing 1440 by 721, we get 1 with a remainder of 719.
Use 1 as the next digit of our solution. 
Result so far: 113574.61
Deduct 721 from 1440 and we're left with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Moving on to step 11:
If we divide 7190 by 721, we get 9 and a remainder of 701.
Use 9 as the next digit of our solution. 
Result so far: 113574.619
If we take 6489 away from 7190, we end up with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

On to step 12:
The number 721 fits into 7010 9 times, leaving a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 113574.6199
Deduct 6489 from 7010 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

The quotient of the division is 113574.6199, and the remainder is 0.00521.
