36131810 divided by 20 
We're looking to find how many times 20 goes into 36131810.

Step 1:
20 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 20

Going ahead to step 2:
If we divide 36 by 20, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 16 after subtracting 20 from 36.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 20

Going ahead to step 3:
If we divide 161 by 20, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 160 from 161 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 20

Step 4:
20 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 20

Step 5:
20 goes into 131 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 1806.0
If we subtract 120 from 131, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 20

Going ahead to step 6:
118 divided by 20 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 18065.0
Subtracting 100 from 118 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 20

Moving on to step 7:
181 divided by 20 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 180659.0
If we subtract 180 from 181, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 20

Step 8:
20 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1806590.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1806590.5
Subtract 100 from 100 to 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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1806590.5
Subtracting 0 from 0 leaves us with 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 11:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1806590.5
Subtracting 0 from 0 leaves us with 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 outcome is 1806590.5, with a leftover of 0.0.
