We divide 64248302 by 503
We want to figure out the number of times 64248302 can be divided by 503.

Let's proceed to step 1:
503 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 503

Moving on to step 2:
The number 503 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 503

Going ahead to step 3:
If we divide 642 by 503, we get 1 and a remainder of 139.
The next digit of our result is 1. 
Result so far: 1.0
If we take 503 away from 642, we end up with 139.
Grab the next digit (4) from the dividend, add it to 139, then carry on: 1394 / 503

On to step 4:
The number 503 fits into 1394 2 times, leaving a remainder of 388.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1006 from 1394 leaves us with 388.
Append the next digit (8) from the dividend to 388 and continue with: 3888 / 503

On to step 5:
If we divide 3888 by 503, we get 7 and a remainder of 367.
Use 7 as the next digit of our solution. 
Result so far: 127.0
The remainder is 367 after subtracting 3521 from 3888.
Grab the next digit (3) from the dividend, add it to 367, then carry on: 3673 / 503

Moving on to step 6:
3673 divided by 503 is 7 with a remainder of 152.
Write down 7 as next digit of the result. 
Result so far: 1277.0
Subtracting 3521 from 3673 leaves us with 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 503

Step 7:
If we divide 1520 by 503, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 12773.0
Subtract 1509 from 1520 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 503

Let's proceed to step 8:
When dividing 112 by 503, we get 0 with a remainder of 112.
Use 0 as the next digit of our solution. 
Result so far: 127730.0
Subtracting 0 from 112 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
503 goes into 1120 2 times with a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 127730.2
Subtracting 1006 from 1120 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
The number 503 fits into 1140 2 times, leaving a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 127730.22
Subtracting 1006 from 1140 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 127730.22 and a remainder of 0.134.
