72799731 divided by 809 
We want to figure out the number of times 72799731 can be divided by 809.

Step 1:
7 divided by 809 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 809

Let's proceed to step 2:
809 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 809

Going ahead to step 3:
The number 809 fits into 727 0 times, leaving a remainder of 727.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 727 leaves us with 727.
Grab the next digit (9) from the dividend, add it to 727, then carry on: 7279 / 809

Going ahead to step 4:
7279 divided by 809 is 8 with a remainder of 807.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6472 from 7279, we get 807.
Include the next digit (9) from the dividend after 807, then repeat: 8079 / 809

Going ahead to step 5:
8079 divided by 809 is 9 with a remainder of 798.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Deduct 7281 from 8079 and we're left with 798.
Fetch the next digit (7) from the dividend, attach it to 798 and continue: 7987 / 809

Let's proceed to step 6:
If we divide 7987 by 809, we get 9 and a remainder of 706.
The next digit of our result is 9. 
Result so far: 899.0
If we subtract 7281 from 7987, we get 706.
Fetch the next digit (3) from the dividend, attach it to 706 and continue: 7063 / 809

On to step 7:
7063 divided by 809 is 8 with a remainder of 591.
Use 8 as the next digit of our solution. 
Result so far: 8998.0
Deduct 6472 from 7063 and we're left with 591.
Grab the next digit (1) from the dividend, add it to 591, then carry on: 5911 / 809

Advancing to step 8:
If we divide 5911 by 809, we get 7 and a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 89987.0
If we subtract 5663 from 5911, 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.

Let's proceed to step 9:
The number 809 fits into 2480 3 times, leaving a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 89987.3
Subtracting 2427 from 2480 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
809 goes into 530 0 times with a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 89987.3
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 11:
If we divide 5300 by 809, we get 6 and a remainder of 446.
The number 6 becomes the next digit in our result. 
Result so far: 89987.306
Subtract 4854 from 5300 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 12:
809 can be fit into 4460 5 times, resulting in a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 89987.3065
Subtracting 4045 from 4460 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 13:
809 goes into 4150 5 times with a remainder of 105.
The next digit of our result is 5. 
Result so far: 89987.30655
If we subtract 4045 from 4150, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 89987.30655, with a leftover of 0.000105.
