66819239 divided by 308 
Our goal is to divide 66819239 by 308.

Moving on to step 1:
When dividing 6 by 308, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 308

Step 2:
308 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 308

Let's proceed to step 3:
308 can be fit into 668 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 52 after subtracting 616 from 668.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 308

Advancing to step 4:
If we divide 521 by 308, we get 1 and a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 308 from 521 leaves us with 213.
Append the next digit (9) from the dividend to 213 and continue with: 2139 / 308

Going ahead to step 5:
The number 308 fits into 2139 6 times, leaving a remainder of 291.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Deduct 1848 from 2139 and we're left with 291.
Include the next digit (2) from the dividend after 291, then repeat: 2912 / 308

Let's proceed to step 6:
If we divide 2912 by 308, we get 9 and a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 2169.0
The remainder is 140 after subtracting 2772 from 2912.
Include the next digit (3) from the dividend after 140, then repeat: 1403 / 308

Advancing to step 7:
If we divide 1403 by 308, we get 4 and a remainder of 171.
The next digit of our result is 4. 
Result so far: 21694.0
Subtract 1232 from 1403 to get 171.
Bring next digit (9) of the dividend behind the 171 and repeat the process: 1719 / 308

Going ahead to step 8:
If we divide 1719 by 308, we get 5 and a remainder of 179.
Put 5 as the next digit of the answer. 
Result so far: 216945.0
Subtract 1540 from 1719 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 9:
When dividing 1790 by 308, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 216945.5
Subtract 1540 from 1790 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
308 goes into 2500 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 216945.58
Deduct 2464 from 2500 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
308 goes into 360 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 216945.581
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
520 divided by 308 is 1 with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 216945.5811
Subtract 308 from 520 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Our division results in 216945.5811 with a remaining 0.00212.
