We look at the division of 381243 by 36 
Let's see how many times 36 fits into 381243.

Let's proceed to step 1:
36 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 36

On to step 2:
36 can be fit into 38 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 36 from 38.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 36

Let's proceed to step 3:
36 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 36

On to step 4:
If we divide 212 by 36, we get 5 and a remainder of 32.
The next digit of our result is 5. 
Result so far: 105.0
If we subtract 180 from 212, we get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 36

Step 5:
The number 36 fits into 324 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1059.0
Deduct 324 from 324 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 36

Advancing to step 6:
36 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10590.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 36, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10590.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 36, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 10590.08
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
36 goes into 120 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 10590.083
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 36, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 10590.0833
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 10590.0833 with a remaining 0.00012.
