We're dividing 81930304 by 316 
Our goal is to divide 81930304 by 316.

On to step 1:
If we divide 8 by 316, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 316

Going ahead to step 2:
316 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 316

Going ahead to step 3:
When dividing 819 by 316, we get 2 with a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 632 away from 819, we end up with 187.
Bring next digit (3) of the dividend behind the 187 and repeat the process: 1873 / 316

Step 4:
When dividing 1873 by 316, we get 5 with a remainder of 293.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 1580 from 1873 to get 293.
Include the next digit (0) from the dividend after 293, then repeat: 2930 / 316

On to step 5:
If we divide 2930 by 316, we get 9 and a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
Subtracting 2844 from 2930 leaves us with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 316

On to step 6:
The number 316 fits into 863 2 times, leaving a remainder of 231.
The next digit of our result is 2. 
Result so far: 2592.0
Deduct 632 from 863 and we're left with 231.
Append the next digit (0) from the dividend to 231 and continue with: 2310 / 316

Step 7:
When dividing 2310 by 316, we get 7 with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 25927.0
Subtracting 2212 from 2310 leaves us with 98.
Take the next digit (4) from the dividend and append it to 98, then repeat: 984 / 316

Going ahead to step 8:
316 can be fit into 984 3 times, resulting in a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 259273.0
The remainder is 36 after subtracting 948 from 984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
316 goes into 360 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 259273.1
Subtract 316 from 360 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 316, we get 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 259273.11
The remainder is 124 after subtracting 316 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 259273.11 with a remaining 0.124.
