664 can be fit into 1740 2 times, resulting in a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 1328 from 1740 leaves us with 412.
Take the next digit (4) from the dividend and append it to 412, then repeat: 4124 / 664

On to step 6:
4124 divided by 664 is 6 with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 326.0
Subtract 3984 from 4124 to get 140.
Take the next digit (8) from the dividend and append it to 140, then repeat: 1408 / 664

Going ahead to step 7:
1408 divided by 664 is 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 3262.0
If we subtract 1328 from 1408, we get 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 664

Let's proceed to step 8:
808 divided by 664 is 1 with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 32621.0
Subtracting 664 from 808 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
If we divide 1440 by 664, we get 2 and a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 32621.2
Subtracting 1328 from 1440 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
1120 divided by 664 is 1 with a remainder of 456.
The next digit of our result is 1. 
Result so far: 32621.21
If we take 664 away from 1120, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 11:
4560 divided by 664 is 6 with a remainder of 576.
Write down 6 as next digit of the result. 
Result so far: 32621.216
Subtract 3984 from 4560 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 12:
664 can be fit into 5760 8 times, resulting in a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 32621.2168
If we take 5312 away from 5760, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 13:
When dividing 4480 by 664, we get 6 with a remainder of 496.
Put 6 as the next digit of the answer. 
Result so far: 32621.21686
If we take 3984 away from 4480, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 14:
The number 664 fits into 4960 7 times, leaving a remainder of 312.
The number 7 becomes the next digit in our result. 
Result so far: 32621.216867
Subtracting 4648 from 4960 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
664 can be fit into 3120 4 times, resulting in a remainder of 464.
The next digit of our result is 4. 
Result so far: 32621.2168674
If we subtract 2656 from 3120, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 16:
The number 664 fits into 4640 6 times, leaving a remainder of 656.
The next digit of our result is 6. 
Result so far: 32621.21686746
Subtract 3984 from 4640 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The quotient of the division is 32621.21686746, and the remainder is 6.56e-07.
