76361728 ÷ 809 
We want to divide 76361728 by 809.

Moving on to step 1:
The number 809 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 809

Going ahead to step 2:
809 can be fit into 76 0 times, resulting in a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 809

Advancing to step 3:
809 goes into 763 0 times with a remainder of 763.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 763 after subtracting 0 from 763.
Grab the next digit (6) from the dividend, add it to 763, then carry on: 7636 / 809

Going ahead to step 4:
7636 divided by 809 is 9 with a remainder of 355.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7281 from 7636 and we're left with 355.
Include the next digit (1) from the dividend after 355, then repeat: 3551 / 809

Going ahead to step 5:
If we divide 3551 by 809, we get 4 and a remainder of 315.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 3236 from 3551 to get 315.
Bring next digit (7) of the dividend behind the 315 and repeat the process: 3157 / 809

On to step 6:
3157 divided by 809 is 3 with a remainder of 730.
The number 3 becomes the next digit in our result. 
Result so far: 943.0
The remainder is 730 after subtracting 2427 from 3157.
Grab the next digit (2) from the dividend, add it to 730, then carry on: 7302 / 809

Let's proceed to step 7:
809 goes into 7302 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9439.0
If we subtract 7281 from 7302, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 809

Step 8:
The number 809 fits into 218 0 times, leaving a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 94390.0
Subtract 0 from 218 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 9:
The number 809 fits into 2180 2 times, leaving a remainder of 562.
The number 2 becomes the next digit in our result. 
Result so far: 94390.2
Subtract 1618 from 2180 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 10:
5620 divided by 809 is 6 with a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 94390.26
If we take 4854 away from 5620, we end up with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Let's proceed to step 11:
809 can be fit into 7660 9 times, resulting in a remainder of 379.
Write down 9 as next digit of the result. 
Result so far: 94390.269
Subtracting 7281 from 7660 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 12:
The number 809 fits into 3790 4 times, leaving a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 94390.2694
If we take 3236 away from 3790, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 13:
If we divide 5540 by 809, we get 6 and a remainder of 686.
Record the quotient 6 as the next digit in the result. 
Result so far: 94390.26946
Deduct 4854 from 5540 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 14:
809 goes into 6860 8 times with a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 94390.269468
If we take 6472 away from 6860, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 15:
3880 divided by 809 is 4 with a remainder of 644.
The next digit of our result is 4. 
Result so far: 94390.2694684
Subtracting 3236 from 3880 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 16:
When dividing 6440 by 809, we get 7 with a remainder of 777.
Use 7 as the next digit of our solution. 
Result so far: 94390.26946847
Subtract 5663 from 6440 to get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

The final result is 94390.26946847 with a remainder of 7.77e-07.
