We're dividing 72818991 by 721 
We want to divide 72818991 by 721.

Step 1:
7 divided by 721 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 721

On to step 2:
72 divided by 721 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 721

On to step 3:
721 goes into 728 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 721 from 728 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 721

Going ahead to step 4:
71 divided by 721 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 721

On to step 5:
If we divide 718 by 721, we get 0 and a remainder of 718.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 718, we end up with 718.
Include the next digit (9) from the dividend after 718, then repeat: 7189 / 721

Going ahead to step 6:
If we divide 7189 by 721, we get 9 and a remainder of 700.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
Deduct 6489 from 7189 and we're left with 700.
Grab the next digit (9) from the dividend, add it to 700, then carry on: 7009 / 721

Moving on to step 7:
721 goes into 7009 9 times with a remainder of 520.
The next digit of our result is 9. 
Result so far: 10099.0
If we take 6489 away from 7009, we end up with 520.
Grab the next digit (1) from the dividend, add it to 520, then carry on: 5201 / 721

Let's proceed to step 8:
721 goes into 5201 7 times with a remainder of 154.
The next digit of our result is 7. 
Result so far: 100997.0
Subtracting 5047 from 5201 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 9:
The number 721 fits into 1540 2 times, leaving a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 100997.2
If we take 1442 away from 1540, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
The number 721 fits into 980 1 times, leaving a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 100997.21
Subtract 721 from 980 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 11:
The number 721 fits into 2590 3 times, leaving a remainder of 427.
Put 3 as the next digit of the answer. 
Result so far: 100997.213
If we take 2163 away from 2590, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 12:
If we divide 4270 by 721, we get 5 and a remainder of 665.
Record the quotient 5 as the next digit in the result. 
Result so far: 100997.2135
If we take 3605 away from 4270, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

On to step 13:
The number 721 fits into 6650 9 times, leaving a remainder of 161.
The next digit of our result is 9. 
Result so far: 100997.21359
Deduct 6489 from 6650 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 14:
If we divide 1610 by 721, we get 2 and a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 100997.213592
Subtract 1442 from 1610 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 15:
If we divide 1680 by 721, we get 2 and a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 100997.2135922
Deduct 1442 from 1680 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 100997.2135922 and a remainder of 2.38e-06.
