77314524 ÷ 503 
Let's see how many times 503 fits into 77314524.

On to step 1:
7 divided by 503 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 503

Step 2:
When dividing 77 by 503, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 503

Let's proceed to step 3:
503 goes into 773 1 times with a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 270 after subtracting 503 from 773.
Bring next digit (1) of the dividend behind the 270 and repeat the process: 2701 / 503

Advancing to step 4:
2701 divided by 503 is 5 with a remainder of 186.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2515 away from 2701, we end up with 186.
Append the next digit (4) from the dividend to 186 and continue with: 1864 / 503

Moving on to step 5:
The number 503 fits into 1864 3 times, leaving a remainder of 355.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 1509 from 1864 and we're left with 355.
Take the next digit (5) from the dividend and append it to 355, then repeat: 3555 / 503

Let's proceed to step 6:
503 can be fit into 3555 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 1537.0
Subtracting 3521 from 3555 leaves us with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 503

Moving on to step 7:
503 can be fit into 342 0 times, resulting in a remainder of 342.
The number 0 becomes the next digit in our result. 
Result so far: 15370.0
The remainder is 342 after subtracting 0 from 342.
Include the next digit (4) from the dividend after 342, then repeat: 3424 / 503

Advancing to step 8:
3424 divided by 503 is 6 with a remainder of 406.
Write down 6 as next digit of the result. 
Result so far: 153706.0
Deduct 3018 from 3424 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 9:
503 can be fit into 4060 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 153706.8
Deduct 4024 from 4060 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
360 divided by 503 is 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 153706.8
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
The number 503 fits into 3600 7 times, leaving a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 153706.807
If we take 3521 away from 3600, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 12:
503 can be fit into 790 1 times, resulting in a remainder of 287.
The next digit of our result is 1. 
Result so far: 153706.8071
The remainder is 287 after subtracting 503 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 13:
2870 divided by 503 is 5 with a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 153706.80715
If we subtract 2515 from 2870, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 14:
503 can be fit into 3550 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 153706.807157
Subtracting 3521 from 3550 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 15:
503 goes into 290 0 times with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 153706.807157
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 16:
If we divide 2900 by 503, we get 5 and a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 153706.80715705
The remainder is 385 after subtracting 2515 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

The final result is 153706.80715705 with a remainder of 3.85e-07.
