70580859 ÷ 503 
We're looking to find how many times 503 goes into 70580859.

Moving on to step 1:
7 divided by 503 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 503

Going ahead to step 2:
70 divided by 503 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 503

Advancing to step 3:
When dividing 705 by 503, we get 1 with a remainder of 202.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 503 from 705 leaves us with 202.
Fetch the next digit (8) from the dividend, attach it to 202 and continue: 2028 / 503

On to step 4:
2028 divided by 503 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2012 from 2028 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 503

Let's proceed to step 5:
The number 503 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtract 0 from 160 to get 160.
Take the next digit (8) from the dividend and append it to 160, then repeat: 1608 / 503

On to step 6:
When dividing 1608 by 503, we get 3 with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 1403.0
If we take 1509 away from 1608, we end up with 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 503

On to step 7:
995 divided by 503 is 1 with a remainder of 492.
The next digit of our result is 1. 
Result so far: 14031.0
If we subtract 503 from 995, we get 492.
Include the next digit (9) from the dividend after 492, then repeat: 4929 / 503

Moving on to step 8:
4929 divided by 503 is 9 with a remainder of 402.
The next digit of our result is 9. 
Result so far: 140319.0
If we subtract 4527 from 4929, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 9:
503 can be fit into 4020 7 times, resulting in a remainder of 499.
The number 7 becomes the next digit in our result. 
Result so far: 140319.7
Subtract 3521 from 4020 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 10:
503 goes into 4990 9 times with a remainder of 463.
Record the quotient 9 as the next digit in the result. 
Result so far: 140319.79
If we subtract 4527 from 4990, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 11:
503 can be fit into 4630 9 times, resulting in a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 140319.799
The remainder is 103 after subtracting 4527 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final result is 140319.799 with a remainder of 0.0103.
