Let's divide 319243 by 81
We want to figure out the number of times 319243 can be divided by 81.

Step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 81

Let's proceed to step 2:
31 divided by 81 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 81

Advancing to step 3:
319 divided by 81 is 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 243 from 319, we get 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 81

On to step 4:
81 goes into 762 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 729 from 762 to get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 81

Moving on to step 5:
When dividing 334 by 81, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 394.0
The remainder is 10 after subtracting 324 from 334.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 81

Advancing to step 6:
103 divided by 81 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3941.0
If we take 81 away from 103, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
When dividing 220 by 81, we get 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 3941.2
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 8:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3941.27
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 3941.271
The remainder is 49 after subtracting 81 from 130.
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 10:
If we divide 490 by 81, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3941.2716
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.

On to step 11:
81 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3941.2716
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 3941.271604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
If we divide 760 by 81, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 3941.2716049
If we take 729 away from 760, we end up 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.

Advancing to step 14:
When dividing 310 by 81, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 3941.27160493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 3941.27160493 and a remainder of 6.7e-08.
