We divide 660903 by 13
Our goal is to divide 660903 by 13.

Moving on to step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 13

Let's proceed to step 2:
66 divided by 13 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
If we take 65 away from 66, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 13

Moving on to step 3:
13 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 10, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 13

Going ahead to step 4:
If we divide 109 by 13, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 508.0
Subtracting 104 from 109 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Let's proceed to step 5:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 5083.0
Deduct 39 from 50 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 13

On to step 6:
13 can be fit into 113 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 50838.0
If we take 104 away from 113, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
13 goes into 90 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 50838.6
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
If we divide 120 by 13, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 50838.69
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 13, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 50838.692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 50838.6923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
13 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 50838.6923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 50838.692307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
13 goes into 90 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 50838.6923076
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 50838.69230769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 50838.69230769 with a remaining 3e-09.
