Let's divide 851813 by 36
We want to figure out the number of times 851813 can be divided by 36.

On to step 1:
When dividing 8 by 36, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 36

Let's proceed to step 2:
36 goes into 85 2 times with 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.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 36

Advancing to step 3:
36 can be fit into 131 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 108 from 131, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 36

Step 4:
When dividing 238 by 36, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 236.0
The remainder is 22 after subtracting 216 from 238.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 36

Step 5:
When dividing 221 by 36, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 2366.0
If we take 216 away from 221, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 36

Advancing to step 6:
53 divided by 36 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 23661.0
Subtracting 36 from 53 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
If we divide 170 by 36, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 23661.4
If we take 144 away from 170, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
When dividing 260 by 36, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 23661.47
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 36 fits into 80 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 23661.472
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 36, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 23661.4722
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 23661.4722 and a remainder of 8e-05.
