We're dividing 780145 by 17 
We want to figure out the number of times 780145 can be divided by 17.

On to step 1:
7 divided by 17 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 17

Let's proceed to step 2:
When dividing 78 by 17, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 68 from 78 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 17

Let's proceed to step 3:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 85 away from 100, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 17

Step 4:
If we divide 151 by 17, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 458.0
Subtracting 136 from 151 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 17

Moving on to step 5:
17 goes into 154 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4589.0
If we take 153 away from 154, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 17

Going ahead to step 6:
17 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 45890.0
The remainder is 15 after subtracting 0 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 17 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 45890.8
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.

On to step 8:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 45890.88
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 45890.88 with a balance of 0.004.
