18659421 divided by 664 
Our goal is to divide 18659421 by 664.

Advancing to step 1:
664 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 664

Step 2:
If we divide 18 by 664, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 664

Advancing to step 3:
186 divided by 664 is 0 with a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 186, we get 186.
Append the next digit (5) from the dividend to 186 and continue with: 1865 / 664

Going ahead to step 4:
1865 divided by 664 is 2 with a remainder of 537.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1328 from 1865 and we're left with 537.
Bring next digit (9) of the dividend behind the 537 and repeat the process: 5379 / 664

On to step 5:
The number 664 fits into 5379 8 times, leaving a remainder of 67.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 5312 from 5379 to get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 664

Going ahead to step 6:
The number 664 fits into 674 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
If we take 664 away from 674, we end up with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 664

Advancing to step 7:
When dividing 102 by 664, we get 0 with a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 2810.0
If we take 0 away from 102, we end up with 102.
Include the next digit (1) from the dividend after 102, then repeat: 1021 / 664

Going ahead to step 8:
664 can be fit into 1021 1 times, resulting in a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 28101.0
Subtract 664 from 1021 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 9:
If we divide 3570 by 664, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 28101.5
Subtract 3320 from 3570 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
When dividing 2500 by 664, we get 3 with a remainder of 508.
Put 3 as the next digit of the answer. 
Result so far: 28101.53
Deduct 1992 from 2500 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 11:
664 can be fit into 5080 7 times, resulting in a remainder of 432.
The number 7 becomes the next digit in our result. 
Result so far: 28101.537
Deduct 4648 from 5080 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
664 goes into 4320 6 times with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 28101.5376
Deduct 3984 from 4320 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
664 goes into 3360 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 28101.53765
The remainder is 40 after subtracting 3320 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 664 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 28101.53765
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
4000 divided by 664 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 28101.5376506
If we take 3984 away from 4000, we end up 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.

Going ahead to step 16:
160 divided by 664 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 28101.5376506
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 28101.5376506 with a remaining 1.6e-07.
