787809 ÷ 79 
We want to figure out the number of times 787809 can be divided by 79.

Step 1:
7 divided by 79 is 0 with 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 79

Advancing to step 2:
When dividing 78 by 79, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 79

Going ahead to step 3:
When dividing 787 by 79, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 76 after subtracting 711 from 787.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 79

Advancing to step 4:
79 can be fit into 768 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 57 after subtracting 711 from 768.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 79

Advancing to step 5:
The number 79 fits into 570 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 997.0
Deduct 553 from 570 and we're left with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 79

Step 6:
79 can be fit into 179 2 times, resulting in a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 9972.0
The remainder is 21 after subtracting 158 from 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 79 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 9972.2
Deduct 158 from 210 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
79 can be fit into 520 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 9972.26
Deduct 474 from 520 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
If we divide 460 by 79, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 9972.265
Subtracting 395 from 460 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
If we divide 650 by 79, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 9972.2658
Subtracting 632 from 650 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
79 can be fit into 180 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 9972.26582
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 79 fits into 220 2 times, leaving a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 9972.265822
If we take 158 away from 220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 9972.265822 with a balance of 6.2e-06.
