Let's divide 538251 by 12
We want to figure out the number of times 538251 can be divided by 12.

Moving on to step 1:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

Going ahead to step 2:
The number 12 fits into 53 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 53 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 12

Let's proceed to step 3:
58 divided by 12 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 48 from 58 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Let's proceed to step 4:
102 divided by 12 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 448.0
If we subtract 96 from 102, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

Let's proceed to step 5:
12 can be fit into 65 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4485.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 12

Let's proceed to step 6:
When dividing 51 by 12, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 44854.0
Subtracting 48 from 51 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.

On to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 44854.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 44854.25
Subtracting 60 from 60 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.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44854.25
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.

Step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 44854.25
Deduct 0 from 0 and we're left 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 result is 44854.25 with a remainder of 0.0.
