We divide 236136 by 81
We're looking to find how many times 81 goes into 236136.

Advancing to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 81

Going ahead to step 2:
If we divide 23 by 81, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 81

On to step 3:
When dividing 236 by 81, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 2.0
If we take 162 away from 236, we end up with 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 81

Moving on to step 4:
When dividing 741 by 81, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 729 from 741 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 81

Going ahead to step 5:
81 goes into 123 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 291.0
Deduct 81 from 123 and we're left with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 81

Moving on to step 6:
The number 81 fits into 426 5 times, leaving a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 2915.0
Subtract 405 from 426 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 81, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2915.2
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 81, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2915.25
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
If we divide 750 by 81, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 2915.259
If we take 729 away from 750, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
210 divided by 81 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2915.2592
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 81 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2915.25925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 2915.259259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
When dividing 210 by 81, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2915.2592592
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
480 divided by 81 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 2915.25925925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 2915.25925925, with a leftover of 7.5e-08.
