Let's divide 77203149 by 507
Let's see how many times 507 fits into 77203149.

On to step 1:
7 divided by 507 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 507

Going ahead to step 2:
The number 507 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 507

Advancing to step 3:
When dividing 772 by 507, we get 1 with a remainder of 265.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 507 from 772, we get 265.
Bring next digit (0) of the dividend behind the 265 and repeat the process: 2650 / 507

On to step 4:
If we divide 2650 by 507, we get 5 and a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2535 away from 2650, we end up with 115.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 507

Going ahead to step 5:
507 goes into 1153 2 times with a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
The remainder is 139 after subtracting 1014 from 1153.
Take the next digit (1) from the dividend and append it to 139, then repeat: 1391 / 507

Advancing to step 6:
The number 507 fits into 1391 2 times, leaving a remainder of 377.
Write down 2 as next digit of the result. 
Result so far: 1522.0
Subtracting 1014 from 1391 leaves us with 377.
Take the next digit (4) from the dividend and append it to 377, then repeat: 3774 / 507

Moving on to step 7:
507 goes into 3774 7 times with a remainder of 225.
Put 7 as the next digit of the answer. 
Result so far: 15227.0
Deduct 3549 from 3774 and we're left with 225.
Append the next digit (9) from the dividend to 225 and continue with: 2259 / 507

Step 8:
The number 507 fits into 2259 4 times, leaving a remainder of 231.
The number 4 becomes the next digit in our result. 
Result so far: 152274.0
If we subtract 2028 from 2259, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 9:
507 goes into 2310 4 times with a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 152274.4
The remainder is 282 after subtracting 2028 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 10:
The number 507 fits into 2820 5 times, leaving a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 152274.45
If we take 2535 away from 2820, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 11:
2850 divided by 507 is 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 152274.455
The remainder is 315 after subtracting 2535 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 152274.455, and the remainder is 0.0315.
