Let's divide 861586 by 36
We're looking to find how many times 36 goes into 861586.

On to step 1:
The number 36 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 36

Let's proceed to step 2:
86 divided by 36 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 72 from 86 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 36

Let's proceed to step 3:
If we divide 141 by 36, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 108 away from 141, we end up with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 36

Going ahead to step 4:
If we divide 335 by 36, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Subtracting 324 from 335 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 36

On to step 5:
36 can be fit into 118 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 2393.0
If we take 108 away from 118, we end up with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 36

On to step 6:
36 can be fit into 106 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 23932.0
Subtracting 72 from 106 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
36 goes into 340 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 23932.9
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
36 can be fit into 160 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 23932.94
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
36 can be fit into 160 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 23932.944
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 23932.944 with a balance of 0.0016.
