Let's divide 310916 by 81
Let's see how many times 81 fits into 310916.

Let's proceed to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 81

Going ahead to step 2:
31 divided by 81 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 81

Step 3:
81 goes into 310 3 times with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 243 from 310 leaves us with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 81

Let's proceed to step 4:
81 goes into 679 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 648 from 679 leaves us with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 81

Moving on to step 5:
If we divide 311 by 81, we get 3 and a remainder of 68.
The next digit of our result is 3. 
Result so far: 383.0
The remainder is 68 after subtracting 243 from 311.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 81

Going ahead to step 6:
If we divide 686 by 81, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 3838.0
Deduct 648 from 686 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 81, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 3838.4
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
When dividing 560 by 81, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 3838.46
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
81 goes into 740 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3838.469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
81 can be fit into 110 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 3838.4691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3838.46913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
81 can be fit into 470 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 3838.469135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
81 goes into 650 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 3838.4691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 81 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3838.4691358
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3838.4691358 with a remaining 2e-08.
