We're dividing 12294803 by 664 
We want to divide 12294803 by 664.

On to step 1:
1 divided by 664 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 664

Let's proceed to step 2:
664 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 664

On to step 3:
If we divide 122 by 664, we get 0 and a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Include the next digit (9) from the dividend after 122, then repeat: 1229 / 664

Advancing to step 4:
The number 664 fits into 1229 1 times, leaving a remainder of 565.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 565 after subtracting 664 from 1229.
Include the next digit (4) from the dividend after 565, then repeat: 5654 / 664

Advancing to step 5:
664 can be fit into 5654 8 times, resulting in a remainder of 342.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 5312 from 5654, we get 342.
Include the next digit (8) from the dividend after 342, then repeat: 3428 / 664

Advancing to step 6:
3428 divided by 664 is 5 with a remainder of 108.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtract 3320 from 3428 to get 108.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 664

On to step 7:
If we divide 1080 by 664, we get 1 and a remainder of 416.
Record the quotient 1 as the next digit in the result. 
Result so far: 1851.0
If we take 664 away from 1080, we end up with 416.
Grab the next digit (3) from the dividend, add it to 416, then carry on: 4163 / 664

Going ahead to step 8:
664 goes into 4163 6 times with a remainder of 179.
Put 6 as the next digit of the answer. 
Result so far: 18516.0
Deduct 3984 from 4163 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
If we divide 1790 by 664, we get 2 and a remainder of 462.
Write down 2 as next digit of the result. 
Result so far: 18516.2
Deduct 1328 from 1790 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 10:
If we divide 4620 by 664, we get 6 and a remainder of 636.
Put 6 as the next digit of the answer. 
Result so far: 18516.26
The remainder is 636 after subtracting 3984 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 11:
664 can be fit into 6360 9 times, resulting in a remainder of 384.
The number 9 becomes the next digit in our result. 
Result so far: 18516.269
The remainder is 384 after subtracting 5976 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
3840 divided by 664 is 5 with a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 18516.2695
Subtracting 3320 from 3840 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
If we divide 5200 by 664, we get 7 and a remainder of 552.
Write down 7 as next digit of the result. 
Result so far: 18516.26957
If we take 4648 away from 5200, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 14:
If we divide 5520 by 664, we get 8 and a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 18516.269578
If we take 5312 away from 5520, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 15:
The number 664 fits into 2080 3 times, leaving a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 18516.2695783
Subtract 1992 from 2080 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
The number 664 fits into 880 1 times, leaving a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 18516.26957831
If we subtract 664 from 880, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 18516.26957831 and a remainder of 2.16e-07.
