536090 divided by 12 
Our goal is to divide 536090 by 12.

Step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 12

Step 2:
The number 12 fits into 53 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 48 from 53 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 12

Let's proceed to step 3:
If we divide 56 by 12, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 48 away from 56, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Let's proceed to step 4:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Deduct 72 from 80 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

On to step 5:
The number 12 fits into 89 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 4467.0
Deduct 84 from 89 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Step 6:
When dividing 50 by 12, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 44674.0
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 44674.1
If we subtract 12 from 20, 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.

Moving on to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 44674.16
Subtract 72 from 80 to 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.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 44674.166
Subtracting 72 from 80 leaves us 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.

The final outcome is 44674.166, with a leftover of 0.0008.
