We look at the division of 71389664 by 308 
Our goal is to divide 71389664 by 308.

Advancing to step 1:
308 can be fit into 7 0 times, resulting in 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.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 308

Advancing to step 2:
If we divide 71 by 308, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 308

On to step 3:
713 divided by 308 is 2 with a remainder of 97.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 616 from 713, we get 97.
Fetch the next digit (8) from the dividend, attach it to 97 and continue: 978 / 308

Going ahead to step 4:
308 can be fit into 978 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 924 from 978 leaves us with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 308

On to step 5:
The number 308 fits into 549 1 times, leaving a remainder of 241.
Put 1 as the next digit of the answer. 
Result so far: 231.0
Subtracting 308 from 549 leaves us with 241.
Take the next digit (6) from the dividend and append it to 241, then repeat: 2416 / 308

Step 6:
2416 divided by 308 is 7 with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 2317.0
Deduct 2156 from 2416 and we're left with 260.
Include the next digit (6) from the dividend after 260, then repeat: 2606 / 308

Going ahead to step 7:
308 can be fit into 2606 8 times, resulting in a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 23178.0
If we subtract 2464 from 2606, we get 142.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 308

Let's proceed to step 8:
308 goes into 1424 4 times with a remainder of 192.
The next digit of our result is 4. 
Result so far: 231784.0
If we take 1232 away from 1424, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 9:
1920 divided by 308 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 231784.6
Subtracting 1848 from 1920 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
The number 308 fits into 720 2 times, leaving a remainder of 104.
The next digit of our result is 2. 
Result so far: 231784.62
Deduct 616 from 720 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
308 goes into 1040 3 times with a remainder of 116.
The next digit of our result is 3. 
Result so far: 231784.623
Subtract 924 from 1040 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 12:
When dividing 1160 by 308, we get 3 with a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 231784.6233
Subtracting 924 from 1160 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 231784.6233 with a remaining 0.00236.
