We look at the division of 778715 by 17 
We want to divide 778715 by 17.

Advancing to step 1:
17 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 17

Advancing to step 2:
17 goes into 77 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 68 from 77 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 17

On to step 3:
The number 17 fits into 98 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 85 from 98 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 17

Going ahead to step 4:
The number 17 fits into 137 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 458.0
Subtract 136 from 137 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 17

Going ahead to step 5:
When dividing 11 by 17, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 4580.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 17

Moving on to step 6:
115 divided by 17 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 45806.0
Subtract 102 from 115 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.

Step 7:
When dividing 130 by 17, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 45806.7
If we take 119 away from 130, we end up 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.

Step 8:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 45806.76
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 17 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 45806.764
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.

On to step 10:
17 can be fit into 120 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 45806.7647
Subtract 119 from 120 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
17 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 45806.7647
Deduct 0 from 10 and we're left with 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 12:
When dividing 100 by 17, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 45806.764705
If we take 85 away from 100, 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.

On to step 13:
17 goes into 150 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 45806.7647058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
140 divided by 17 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 45806.76470588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 45806.76470588, with a leftover of 4e-09.
