We divide 316012 by 81
We're looking to find how many times 81 goes into 316012.

Advancing to step 1:
81 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 81

On 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
The remainder is 31 after subtracting 0 from 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 81

Advancing to step 3:
81 goes into 316 3 times with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 243 from 316, we get 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 81

Moving on to step 4:
If we divide 730 by 81, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 729 from 730 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 81

Let's proceed to step 5:
81 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 390.0
If we take 0 away from 11, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 81

Let's proceed to step 6:
112 divided by 81 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3901.0
Subtracting 81 from 112 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 3901.3
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 8:
If we divide 670 by 81, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 3901.38
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 3901.382
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
The number 81 fits into 580 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3901.3827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
81 goes into 130 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 3901.38271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
81 goes into 490 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3901.382716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3901.382716
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
When dividing 400 by 81, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 3901.38271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 3901.38271604 with a remainder of 7.6e-08.
