We're dividing 43360260 by 668 
We want to figure out the number of times 43360260 can be divided by 668.

Advancing to step 1:
668 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
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 668

Moving on to step 2:
43 divided by 668 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 668

Moving on to step 3:
433 divided by 668 is 0 with a remainder of 433.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 433 to get 433.
Grab the next digit (6) from the dividend, add it to 433, then carry on: 4336 / 668

Let's proceed to step 4:
668 can be fit into 4336 6 times, resulting in a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 328 after subtracting 4008 from 4336.
Fetch the next digit (0) from the dividend, attach it to 328 and continue: 3280 / 668

Moving on to step 5:
If we divide 3280 by 668, we get 4 and a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 2672 from 3280 to get 608.
Include the next digit (2) from the dividend after 608, then repeat: 6082 / 668

On to step 6:
The number 668 fits into 6082 9 times, leaving a remainder of 70.
The next digit of our result is 9. 
Result so far: 649.0
The remainder is 70 after subtracting 6012 from 6082.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 668

On to step 7:
If we divide 706 by 668, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 6491.0
If we subtract 668 from 706, we get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 668

Going ahead to step 8:
668 can be fit into 380 0 times, resulting in a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 64910.0
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 9:
3800 divided by 668 is 5 with a remainder of 460.
Write down 5 as next digit of the result. 
Result so far: 64910.5
If we subtract 3340 from 3800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 10:
668 goes into 4600 6 times with a remainder of 592.
The number 6 becomes the next digit in our result. 
Result so far: 64910.56
The remainder is 592 after subtracting 4008 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 11:
5920 divided by 668 is 8 with a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 64910.568
Subtracting 5344 from 5920 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 12:
668 goes into 5760 8 times with a remainder of 416.
The next digit of our result is 8. 
Result so far: 64910.5688
If we take 5344 away from 5760, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 64910.5688 and a remainder of 0.00416.
