We look at the division of 12050305 by 438 
Let's see how many times 438 fits into 12050305.

Going ahead to step 1:
The number 438 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 438

Going ahead to step 2:
438 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 438

Let's proceed to step 3:
When dividing 120 by 438, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Include the next digit (5) from the dividend after 120, then repeat: 1205 / 438

Step 4:
438 goes into 1205 2 times with a remainder of 329.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 876 away from 1205, we end up with 329.
Include the next digit (0) from the dividend after 329, then repeat: 3290 / 438

Moving on to step 5:
The number 438 fits into 3290 7 times, leaving a remainder of 224.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 3066 from 3290 leaves us with 224.
Grab the next digit (3) from the dividend, add it to 224, then carry on: 2243 / 438

On to step 6:
2243 divided by 438 is 5 with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 275.0
The remainder is 53 after subtracting 2190 from 2243.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 438

Let's proceed to step 7:
If we divide 530 by 438, we get 1 and a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 2751.0
If we subtract 438 from 530, we get 92.
Grab the next digit (5) from the dividend, add it to 92, then carry on: 925 / 438

Advancing to step 8:
When dividing 925 by 438, we get 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 27512.0
If we take 876 away from 925, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
If we divide 490 by 438, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 27512.1
If we subtract 438 from 490, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
438 can be fit into 520 1 times, resulting in a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 27512.11
The remainder is 82 after subtracting 438 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 27512.11 with a remaining 0.082.
