We look at the division of 66962944 by 503 
We're looking to find how many times 503 goes into 66962944.

On to step 1:
503 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 503

Going ahead to step 2:
503 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 503

Let's proceed to step 3:
503 can be fit into 669 1 times, resulting in a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 503 from 669 and we're left with 166.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 503

Advancing to step 4:
When dividing 1666 by 503, we get 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1509 from 1666, we get 157.
Bring next digit (2) of the dividend behind the 157 and repeat the process: 1572 / 503

Going ahead to step 5:
The number 503 fits into 1572 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we subtract 1509 from 1572, we get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 503

Going ahead to step 6:
The number 503 fits into 639 1 times, leaving a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 1331.0
Deduct 503 from 639 and we're left with 136.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 503

On to step 7:
503 can be fit into 1364 2 times, resulting in a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 13312.0
Deduct 1006 from 1364 and we're left with 358.
Bring next digit (4) of the dividend behind the 358 and repeat the process: 3584 / 503

Going ahead to step 8:
The number 503 fits into 3584 7 times, leaving a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 133127.0
Deduct 3521 from 3584 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
503 goes into 630 1 times with a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 133127.1
Deduct 503 from 630 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
503 goes into 1270 2 times with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 133127.12
Deduct 1006 from 1270 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 11:
When dividing 2640 by 503, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 133127.125
Deduct 2515 from 2640 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
503 goes into 1250 2 times with a remainder of 244.
The next digit of our result is 2. 
Result so far: 133127.1252
Subtracting 1006 from 1250 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 13:
When dividing 2440 by 503, we get 4 with a remainder of 428.
The next digit of our result is 4. 
Result so far: 133127.12524
If we take 2012 away from 2440, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 14:
503 can be fit into 4280 8 times, resulting in a remainder of 256.
The next digit of our result is 8. 
Result so far: 133127.125248
Subtract 4024 from 4280 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 15:
The number 503 fits into 2560 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 133127.1252485
The remainder is 45 after subtracting 2515 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
The number 503 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 133127.1252485
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

In conclusion, the division gives 133127.1252485 with a balance of 4.5e-07.
