We look at the division of 876409 by 17 
We're looking to find how many times 17 goes into 876409.

Going ahead to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 17

Moving on to step 2:
17 goes into 87 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 85 away from 87, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 17

Step 3:
The number 17 fits into 26 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 17 from 26, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 17

Moving on to step 4:
When dividing 94 by 17, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 515.0
Deduct 85 from 94 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 17

On to step 5:
17 can be fit into 90 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5155.0
If we take 85 away from 90, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 17

Step 6:
59 divided by 17 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 51553.0
If we subtract 51 from 59, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 17, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 51553.4
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.

Advancing to step 8:
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: 51553.47
If we take 119 away from 120, we end up 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.

Going ahead to step 9:
17 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 51553.47
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 10:
17 goes into 100 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 51553.4705
Subtracting 85 from 100 leaves us 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.

Advancing to step 11:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 51553.47058
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.

Moving on to step 12:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 51553.470588
Deduct 136 from 140 and we're left 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 51553.470588, with a leftover of 4e-07.
