We look at the division of 76660571 by 308 
We want to figure out the number of times 76660571 can be divided by 308.

Moving on to step 1:
The number 308 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 308

Step 2:
308 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 308

Going ahead to step 3:
308 goes into 766 2 times with a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 616 from 766 and we're left with 150.
Fetch the next digit (6) from the dividend, attach it to 150 and continue: 1506 / 308

Let's proceed to step 4:
308 goes into 1506 4 times with a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 1232 away from 1506, we end up with 274.
Fetch the next digit (0) from the dividend, attach it to 274 and continue: 2740 / 308

Let's proceed to step 5:
If we divide 2740 by 308, we get 8 and a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 248.0
Subtract 2464 from 2740 to get 276.
Bring next digit (5) of the dividend behind the 276 and repeat the process: 2765 / 308

On to step 6:
308 goes into 2765 8 times with a remainder of 301.
Record the quotient 8 as the next digit in the result. 
Result so far: 2488.0
Subtracting 2464 from 2765 leaves us with 301.
Grab the next digit (7) from the dividend, add it to 301, then carry on: 3017 / 308

Let's proceed to step 7:
3017 divided by 308 is 9 with a remainder of 245.
Write down 9 as next digit of the result. 
Result so far: 24889.0
If we take 2772 away from 3017, we end up with 245.
Grab the next digit (1) from the dividend, add it to 245, then carry on: 2451 / 308

On to step 8:
The number 308 fits into 2451 7 times, leaving a remainder of 295.
The next digit of our result is 7. 
Result so far: 248897.0
The remainder is 295 after subtracting 2156 from 2451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 9:
When dividing 2950 by 308, we get 9 with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 248897.9
Subtract 2772 from 2950 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
308 goes into 1780 5 times with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 248897.95
The remainder is 240 after subtracting 1540 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
308 can be fit into 2400 7 times, resulting in a remainder of 244.
Put 7 as the next digit of the answer. 
Result so far: 248897.957
The remainder is 244 after subtracting 2156 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 12:
2440 divided by 308 is 7 with a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 248897.9577
If we take 2156 away from 2440, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

After the division, we end up with 248897.9577 and a remainder of 0.00284.
