We're dividing 17658238 by 668 
We want to figure out the number of times 17658238 can be divided by 668.

Going ahead to step 1:
1 divided by 668 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 668

On to step 2:
17 divided by 668 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 668

Let's proceed to step 3:
176 divided by 668 is 0 with a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 176 to get 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 668

Advancing to step 4:
When dividing 1765 by 668, we get 2 with a remainder of 429.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 429 after subtracting 1336 from 1765.
Fetch the next digit (8) from the dividend, attach it to 429 and continue: 4298 / 668

Advancing to step 5:
668 can be fit into 4298 6 times, resulting in a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 4008 away from 4298, we end up with 290.
Append the next digit (2) from the dividend to 290 and continue with: 2902 / 668

Step 6:
2902 divided by 668 is 4 with a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 264.0
Deduct 2672 from 2902 and we're left with 230.
Take the next digit (3) from the dividend and append it to 230, then repeat: 2303 / 668

On to step 7:
668 can be fit into 2303 3 times, resulting in a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 2643.0
Subtract 2004 from 2303 to get 299.
Fetch the next digit (8) from the dividend, attach it to 299 and continue: 2998 / 668

Moving on to step 8:
668 goes into 2998 4 times with a remainder of 326.
The number 4 becomes the next digit in our result. 
Result so far: 26434.0
If we subtract 2672 from 2998, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 9:
3260 divided by 668 is 4 with a remainder of 588.
Put 4 as the next digit of the answer. 
Result so far: 26434.4
Subtracting 2672 from 3260 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 10:
5880 divided by 668 is 8 with a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 26434.48
Subtract 5344 from 5880 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 11:
When dividing 5360 by 668, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26434.488
Deduct 5344 from 5360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 26434.488, and the remainder is 0.0016.
