Let's divide 420656 by 17
We want to divide 420656 by 17.

Advancing to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 17

On to step 2:
17 goes into 42 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we take 34 away from 42, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 17

Advancing to step 3:
If we divide 80 by 17, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 68 from 80 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 17

Moving on to step 4:
126 divided by 17 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 247.0
Deduct 119 from 126 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 17

Advancing to step 5:
If we divide 75 by 17, we get 4 and a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 2474.0
The remainder is 7 after subtracting 68 from 75.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 17

Step 6:
If we divide 76 by 17, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 24744.0
If we subtract 68 from 76, 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.

On to step 7:
The number 17 fits into 80 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 24744.4
Subtracting 68 from 80 leaves us with 12.
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 8:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 24744.47
Subtract 119 from 120 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 24744.47
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.

On to step 10:
The number 17 fits into 100 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 24744.4705
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 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: 24744.47058
Subtracting 136 from 150 leaves us 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.

Moving on to step 12:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 24744.470588
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.

After the division, we end up with 24744.470588 and a remainder of 4e-07.
