We're dividing 76646991 by 503 
We're looking to find how many times 503 goes into 76646991.

Going ahead to step 1:
7 divided by 503 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 503

Step 2:
503 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 503

Going ahead to step 3:
The number 503 fits into 766 1 times, leaving a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 503 from 766, we get 263.
Fetch the next digit (4) from the dividend, attach it to 263 and continue: 2634 / 503

Advancing to step 4:
503 goes into 2634 5 times with a remainder of 119.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2515 away from 2634, we end up with 119.
Take the next digit (6) from the dividend and append it to 119, then repeat: 1196 / 503

Advancing to step 5:
The number 503 fits into 1196 2 times, leaving a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtracting 1006 from 1196 leaves us with 190.
Bring next digit (9) of the dividend behind the 190 and repeat the process: 1909 / 503

Step 6:
1909 divided by 503 is 3 with a remainder of 400.
Use 3 as the next digit of our solution. 
Result so far: 1523.0
If we subtract 1509 from 1909, we get 400.
Append the next digit (9) from the dividend to 400 and continue with: 4009 / 503

Let's proceed to step 7:
If we divide 4009 by 503, we get 7 and a remainder of 488.
Use 7 as the next digit of our solution. 
Result so far: 15237.0
The remainder is 488 after subtracting 3521 from 4009.
Take the next digit (1) from the dividend and append it to 488, then repeat: 4881 / 503

Going ahead to step 8:
503 goes into 4881 9 times with a remainder of 354.
Write down 9 as next digit of the result. 
Result so far: 152379.0
Subtracting 4527 from 4881 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
When dividing 3540 by 503, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 152379.7
The remainder is 19 after subtracting 3521 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
The number 503 fits into 190 0 times, leaving a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 152379.7
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 11:
503 can be fit into 1900 3 times, resulting in a remainder of 391.
Put 3 as the next digit of the answer. 
Result so far: 152379.703
Subtracting 1509 from 1900 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 12:
503 can be fit into 3910 7 times, resulting in a remainder of 389.
Write down 7 as next digit of the result. 
Result so far: 152379.7037
If we take 3521 away from 3910, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 13:
If we divide 3890 by 503, we get 7 and a remainder of 369.
The next digit of our result is 7. 
Result so far: 152379.70377
Subtracting 3521 from 3890 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Our division results in 152379.70377 with a remaining 0.000369.
