Let's divide 780609 by 17
We want to divide 780609 by 17.

Advancing to step 1:
17 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
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 / 17

Moving on to step 2:
17 goes into 78 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 68 from 78 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 17

Advancing to step 3:
17 can be fit into 100 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 15 after subtracting 85 from 100.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 17

Going ahead to step 4:
The number 17 fits into 156 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Subtracting 153 from 156 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 17

On to step 5:
If we divide 30 by 17, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 4591.0
The remainder is 13 after subtracting 17 from 30.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 17

Going ahead to step 6:
17 goes into 139 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 45918.0
Subtract 136 from 139 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
17 goes into 30 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 45918.1
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
130 divided by 17 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 45918.17
Subtracting 119 from 130 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 45918.176
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
17 goes into 80 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 45918.1764
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
17 can be fit into 120 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 45918.17647
Deduct 119 from 120 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 45918.17647
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 17, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 45918.1764705
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 45918.17647058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 45918.17647058, with a leftover of 1.4e-08.
