We're dividing 70259099 by 273 
Let's see how many times 273 fits into 70259099.

On to step 1:
The number 273 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 273

Going ahead to step 2:
The number 273 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 273

Moving on to step 3:
If we divide 702 by 273, we get 2 and a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 546 from 702 and we're left with 156.
Take the next digit (5) from the dividend and append it to 156, then repeat: 1565 / 273

Going ahead to step 4:
273 goes into 1565 5 times with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 1365 from 1565, we get 200.
Take the next digit (9) from the dividend and append it to 200, then repeat: 2009 / 273

Going ahead to step 5:
273 can be fit into 2009 7 times, resulting in a remainder of 98.
The next digit of our result is 7. 
Result so far: 257.0
If we take 1911 away from 2009, we end up with 98.
Fetch the next digit (0) from the dividend, attach it to 98 and continue: 980 / 273

Moving on to step 6:
273 goes into 980 3 times with a remainder of 161.
The number 3 becomes the next digit in our result. 
Result so far: 2573.0
Subtracting 819 from 980 leaves us with 161.
Include the next digit (9) from the dividend after 161, then repeat: 1619 / 273

Advancing to step 7:
1619 divided by 273 is 5 with a remainder of 254.
Put 5 as the next digit of the answer. 
Result so far: 25735.0
Subtracting 1365 from 1619 leaves us with 254.
Append the next digit (9) from the dividend to 254 and continue with: 2549 / 273

Advancing to step 8:
When dividing 2549 by 273, we get 9 with a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 257359.0
If we take 2457 away from 2549, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
273 goes into 920 3 times with a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 257359.3
If we subtract 819 from 920, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 10:
If we divide 1010 by 273, we get 3 and a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 257359.33
If we take 819 away from 1010, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Our division results in 257359.33 with a remaining 0.191.
