Let's divide 308350 by 81
We want to figure out the number of times 308350 can be divided by 81.

Step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 81

Advancing to step 2:
81 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 81

Going ahead to step 3:
81 goes into 308 3 times with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 243 from 308, we get 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 81

Going ahead to step 4:
653 divided by 81 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 38.0
The remainder is 5 after subtracting 648 from 653.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 81

Going ahead to step 5:
81 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 380.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 81

Advancing to step 6:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 3806.0
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
640 divided by 81 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 3806.7
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
81 can be fit into 730 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 3806.79
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
81 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 3806.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 81, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 3806.7901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
81 goes into 190 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 3806.79012
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
280 divided by 81 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 3806.790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
81 can be fit into 370 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 3806.7901234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
If we divide 460 by 81, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 3806.79012345
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 3806.79012345 with a remainder of 5.5e-08.
