72316158 divided by 503 
We want to divide 72316158 by 503.

Moving on to step 1:
If we divide 7 by 503, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 503

Step 2:
The number 503 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 503

On to step 3:
If we divide 723 by 503, we get 1 and a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 503 away from 723, we end up with 220.
Append the next digit (1) from the dividend to 220 and continue with: 2201 / 503

Advancing to step 4:
2201 divided by 503 is 4 with a remainder of 189.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2012 away from 2201, we end up with 189.
Append the next digit (6) from the dividend to 189 and continue with: 1896 / 503

Going ahead to step 5:
503 can be fit into 1896 3 times, resulting in a remainder of 387.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 387 after subtracting 1509 from 1896.
Take the next digit (1) from the dividend and append it to 387, then repeat: 3871 / 503

Moving on to step 6:
If we divide 3871 by 503, we get 7 and a remainder of 350.
Put 7 as the next digit of the answer. 
Result so far: 1437.0
If we take 3521 away from 3871, we end up with 350.
Grab the next digit (5) from the dividend, add it to 350, then carry on: 3505 / 503

Advancing to step 7:
If we divide 3505 by 503, we get 6 and a remainder of 487.
Write down 6 as next digit of the result. 
Result so far: 14376.0
If we take 3018 away from 3505, we end up with 487.
Append the next digit (8) from the dividend to 487 and continue with: 4878 / 503

Step 8:
When dividing 4878 by 503, we get 9 with a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 143769.0
If we take 4527 away from 4878, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
The number 503 fits into 3510 6 times, leaving a remainder of 492.
Put 6 as the next digit of the answer. 
Result so far: 143769.6
Deduct 3018 from 3510 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 10:
503 can be fit into 4920 9 times, resulting in a remainder of 393.
Record the quotient 9 as the next digit in the result. 
Result so far: 143769.69
Subtracting 4527 from 4920 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 11:
If we divide 3930 by 503, we get 7 and a remainder of 409.
Write down 7 as next digit of the result. 
Result so far: 143769.697
Deduct 3521 from 3930 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 12:
The number 503 fits into 4090 8 times, leaving a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 143769.6978
If we take 4024 away from 4090, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
503 goes into 660 1 times with a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 143769.69781
If we subtract 503 from 660, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 14:
If we divide 1570 by 503, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 143769.697813
Subtracting 1509 from 1570 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 15:
When dividing 610 by 503, we get 1 with a remainder of 107.
The next digit of our result is 1. 
Result so far: 143769.6978131
If we subtract 503 from 610, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 16:
The number 503 fits into 1070 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 143769.69781312
If we subtract 1006 from 1070, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 143769.69781312 with a remaining 6.4e-08.
