We divide 13021 by 12
We want to divide 13021 by 12.

Step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 12

Going ahead to step 2:
When dividing 13 by 12, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 12 away from 13, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

On to step 3:
12 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Moving on to step 4:
12 goes into 102 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 96 from 102 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Step 5:
12 goes into 61 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
The remainder is 1 after subtracting 60 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
The number 12 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1085.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1085.08
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1085.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1085.0833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 1085.0833 with a balance of 4e-05.
