We look at the division of 81436 by 3 
Let's see how many times 3 fits into 81436.

On to step 1:
3 goes into 8 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Moving on to step 2:
3 goes into 21 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 21 from 21, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Moving on to step 3:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
Deduct 3 from 4 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

On to step 4:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 2714.0
Subtract 12 from 13 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Advancing to step 5:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 27145.0
Deduct 15 from 16 and we're left 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.

Going ahead to step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 27145.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 27145.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 27145.33 with a balance of 0.001.
