478631 ÷ 17 
We're looking to find how many times 17 goes into 478631.

Going ahead to step 1:
When dividing 4 by 17, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 17

Step 2:
When dividing 47 by 17, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 34 from 47 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 17

Step 3:
If we divide 138 by 17, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 136 away from 138, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 17

Advancing to step 4:
17 can be fit into 26 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 17 from 26 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 17

On to step 5:
When dividing 93 by 17, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 2815.0
Subtract 85 from 93 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 17

On to step 6:
If we divide 81 by 17, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 28154.0
If we take 68 away from 81, we end up with 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:
The number 17 fits into 130 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 28154.7
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.

Moving on to step 8:
110 divided by 17 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 28154.76
Deduct 102 from 110 and we're left 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.

Let's proceed to step 9:
If we divide 80 by 17, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 28154.764
If we subtract 68 from 80, we 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:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 28154.7647
Subtracting 119 from 120 leaves us 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 11:
17 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 28154.7647
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.

Advancing to step 12:
If we divide 100 by 17, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 28154.764705
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.

Moving on to step 13:
When dividing 150 by 17, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 28154.7647058
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.

Going ahead to step 14:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 28154.76470588
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 result is 28154.76470588 with a remainder of 4e-09.
