We look at the division of 17240656 by 678 
We're looking to find how many times 678 goes into 17240656.

On to step 1:
When dividing 1 by 678, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 678

On to step 2:
678 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 678

Going ahead to step 3:
678 goes into 172 0 times with a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 172 after subtracting 0 from 172.
Fetch the next digit (4) from the dividend, attach it to 172 and continue: 1724 / 678

Advancing to step 4:
678 goes into 1724 2 times with a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 368 after subtracting 1356 from 1724.
Bring next digit (0) of the dividend behind the 368 and repeat the process: 3680 / 678

On to step 5:
The number 678 fits into 3680 5 times, leaving a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 3390 from 3680 to get 290.
Grab the next digit (6) from the dividend, add it to 290, then carry on: 2906 / 678

Let's proceed to step 6:
678 goes into 2906 4 times with a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 254.0
Deduct 2712 from 2906 and we're left with 194.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 678

Moving on to step 7:
The number 678 fits into 1945 2 times, leaving a remainder of 589.
Use 2 as the next digit of our solution. 
Result so far: 2542.0
Subtracting 1356 from 1945 leaves us with 589.
Take the next digit (6) from the dividend and append it to 589, then repeat: 5896 / 678

On to step 8:
678 goes into 5896 8 times with a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 25428.0
Subtracting 5424 from 5896 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 9:
678 can be fit into 4720 6 times, resulting in a remainder of 652.
Use 6 as the next digit of our solution. 
Result so far: 25428.6
Subtracting 4068 from 4720 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 10:
The number 678 fits into 6520 9 times, leaving a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 25428.69
Subtracting 6102 from 6520 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 11:
The number 678 fits into 4180 6 times, leaving a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 25428.696
The remainder is 112 after subtracting 4068 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
678 can be fit into 1120 1 times, resulting in a remainder of 442.
Put 1 as the next digit of the answer. 
Result so far: 25428.6961
The remainder is 442 after subtracting 678 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 13:
When dividing 4420 by 678, we get 6 with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 25428.69616
If we subtract 4068 from 4420, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 14:
678 can be fit into 3520 5 times, resulting in a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 25428.696165
The remainder is 130 after subtracting 3390 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 15:
If we divide 1300 by 678, we get 1 and a remainder of 622.
Write down 1 as next digit of the result. 
Result so far: 25428.6961651
Deduct 678 from 1300 and we're left with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 16:
678 can be fit into 6220 9 times, resulting in a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 25428.69616519
Deduct 6102 from 6220 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 25428.69616519, and the remainder is 1.18e-07.
