Let's divide 809570 by 79
We want to figure out the number of times 809570 can be divided by 79.

Step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 79

Moving on to step 2:
80 divided by 79 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 79 from 80 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 79

Going ahead to step 3:
If we divide 19 by 79, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 79

Step 4:
195 divided by 79 is 2 with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we subtract 158 from 195, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 79

Step 5:
If we divide 377 by 79, we get 4 and a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 1024.0
If we take 316 away from 377, we end up with 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 79

Step 6:
610 divided by 79 is 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 10247.0
The remainder is 57 after subtracting 553 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
570 divided by 79 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 10247.7
Subtracting 553 from 570 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
79 can be fit into 170 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 10247.72
Subtracting 158 from 170 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 79, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 10247.721
The remainder is 41 after subtracting 79 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
410 divided by 79 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10247.7215
If we take 395 away from 410, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
79 can be fit into 150 1 times, resulting in a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 10247.72151
Subtract 79 from 150 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
When dividing 710 by 79, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 10247.721518
If we subtract 632 from 710, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
780 divided by 79 is 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 10247.7215189
The remainder is 69 after subtracting 711 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
The number 79 fits into 690 8 times, leaving a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 10247.72151898
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 10247.72151898 with a balance of 5.8e-08.
