Let's divide 428454 by 17
We're looking to find how many times 17 goes into 428454.

Step 1:
If we divide 4 by 17, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

Going ahead to step 2:
17 goes into 42 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 34 from 42, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 17

Advancing to step 3:
88 divided by 17 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 85 from 88, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 17

Going ahead to step 4:
If we divide 34 by 17, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 34 from 34 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 17

Moving on to step 5:
The number 17 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 2520.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 17

Going ahead to step 6:
54 divided by 17 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 25203.0
The remainder is 3 after subtracting 51 from 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 17 fits into 30 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 25203.1
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
130 divided by 17 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 25203.17
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 17 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 25203.176
Subtracting 102 from 110 leaves us 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.

Step 10:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 25203.1764
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
When dividing 120 by 17, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 25203.17647
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.

Step 12:
10 divided by 17 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 25203.17647
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 25203.1764705
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.

Step 14:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 25203.17647058
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.

The final result is 25203.17647058 with a remainder of 1.4e-08.
