We look at the division of 858870 by 36 
We're looking to find how many times 36 goes into 858870.

Step 1:
8 divided by 36 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 36

Let's proceed to step 2:
If we divide 85 by 36, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 72 from 85, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 36

Moving on to step 3:
When dividing 138 by 36, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 30 after subtracting 108 from 138.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 36

Going ahead to step 4:
If we divide 308 by 36, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtract 288 from 308 to get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 36

Let's proceed to step 5:
When dividing 207 by 36, we get 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 2385.0
Deduct 180 from 207 and we're left with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 36

Let's proceed to step 6:
When dividing 270 by 36, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 23857.0
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 36, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 23857.5
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 36 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23857.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 36 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23857.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 23857.5 with a remainder of 0.0.
