We're dividing 64772090 by 503 
Our goal is to divide 64772090 by 503.

Advancing to step 1:
If we divide 6 by 503, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 503

Moving on to step 2:
The number 503 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 503

Moving on to step 3:
The number 503 fits into 647 1 times, leaving a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 503 from 647 and we're left with 144.
Grab the next digit (7) from the dividend, add it to 144, then carry on: 1447 / 503

Advancing to step 4:
1447 divided by 503 is 2 with a remainder of 441.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1006 from 1447, we get 441.
Bring next digit (2) of the dividend behind the 441 and repeat the process: 4412 / 503

Advancing to step 5:
The number 503 fits into 4412 8 times, leaving a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 4024 from 4412, we get 388.
Bring next digit (0) of the dividend behind the 388 and repeat the process: 3880 / 503

Step 6:
3880 divided by 503 is 7 with a remainder of 359.
The number 7 becomes the next digit in our result. 
Result so far: 1287.0
The remainder is 359 after subtracting 3521 from 3880.
Append the next digit (9) from the dividend to 359 and continue with: 3599 / 503

Going ahead to step 7:
503 goes into 3599 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 12877.0
Deduct 3521 from 3599 and we're left with 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 503

Going ahead to step 8:
503 goes into 780 1 times with a remainder of 277.
The next digit of our result is 1. 
Result so far: 128771.0
Subtracting 503 from 780 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 9:
503 goes into 2770 5 times with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 128771.5
If we take 2515 away from 2770, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 10:
503 goes into 2550 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 128771.55
If we take 2515 away from 2550, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 128771.55, and the remainder is 0.035.
