We look at the division of 80956310 by 17 
We want to divide 80956310 by 17.

Step 1:
17 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
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 17

Let's proceed to step 2:
When dividing 80 by 17, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 68 from 80 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 17

On to step 3:
17 can be fit into 129 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 119 from 129 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 17

Moving on to step 4:
17 can be fit into 105 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 476.0
If we take 102 away from 105, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 17

Moving on to step 5:
The number 17 fits into 36 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4762.0
Subtract 34 from 36 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 17

Moving on to step 6:
When dividing 23 by 17, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 47621.0
If we take 17 away from 23, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 17

On to step 7:
The number 17 fits into 61 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 476213.0
Subtract 51 from 61 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 17

On to step 8:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4762135.0
Deduct 85 from 100 and we're left 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.

Let's proceed to step 9:
17 goes into 150 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 4762135.8
If we take 136 away from 150, we end up 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.

Let's proceed to step 10:
When dividing 140 by 17, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4762135.88
The remainder is 4 after subtracting 136 from 140.
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 result is 4762135.88 with a remainder of 0.004.
