Let's divide 6590 by 12
We want to figure out the number of times 6590 can be divided by 12.

Going ahead to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Let's proceed to step 2:
When dividing 65 by 12, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 65 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 12

Moving on to step 3:
When dividing 59 by 12, we get 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 48 from 59 to get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 12

Step 4:
The number 12 fits into 110 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 549.0
Deduct 108 from 110 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.

Going ahead to step 5:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 549.1
Subtracting 12 from 20 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.

Moving on to step 6:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 549.16
Deduct 72 from 80 and we're left 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.

Moving on to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 549.166
Deduct 72 from 80 and we're left 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 result is 549.166 with a remainder of 0.0008.
