Let's divide 43218478 by 666
We want to divide 43218478 by 666.

Going ahead to step 1:
666 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 666

Let's proceed to step 2:
666 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 666

Advancing to step 3:
432 divided by 666 is 0 with a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 432, we get 432.
Bring next digit (1) of the dividend behind the 432 and repeat the process: 4321 / 666

Moving on to step 4:
666 can be fit into 4321 6 times, resulting in a remainder of 325.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 3996 from 4321 to get 325.
Bring next digit (8) of the dividend behind the 325 and repeat the process: 3258 / 666

Moving on to step 5:
3258 divided by 666 is 4 with a remainder of 594.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 2664 from 3258 leaves us with 594.
Grab the next digit (4) from the dividend, add it to 594, then carry on: 5944 / 666

Let's proceed to step 6:
666 can be fit into 5944 8 times, resulting in a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
If we subtract 5328 from 5944, we get 616.
Include the next digit (7) from the dividend after 616, then repeat: 6167 / 666

Advancing to step 7:
If we divide 6167 by 666, we get 9 and a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 6489.0
Deduct 5994 from 6167 and we're left with 173.
Bring next digit (8) of the dividend behind the 173 and repeat the process: 1738 / 666

Moving on to step 8:
1738 divided by 666 is 2 with a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 64892.0
If we take 1332 away from 1738, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 9:
666 can be fit into 4060 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 64892.6
Subtract 3996 from 4060 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
666 goes into 640 0 times with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 64892.6
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
666 can be fit into 6400 9 times, resulting in a remainder of 406.
The next digit of our result is 9. 
Result so far: 64892.609
Subtract 5994 from 6400 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 12:
The number 666 fits into 4060 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 64892.6096
The remainder is 64 after subtracting 3996 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
666 can be fit into 640 0 times, resulting in a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 64892.6096
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
666 can be fit into 6400 9 times, resulting in a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 64892.609609
Deduct 5994 from 6400 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 15:
The number 666 fits into 4060 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 64892.6096096
Subtract 3996 from 4060 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
666 can be fit into 640 0 times, resulting in a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 64892.6096096
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 64892.6096096 with a remainder of 6.4e-07.
