124947 divided by 12 
Our goal is to divide 124947 by 12.

Advancing to step 1:
12 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Advancing to step 2:
The number 12 fits into 12 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 12

On to step 3:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Moving on to step 4:
12 goes into 49 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we take 48 away from 49, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 12

On to step 5:
If we divide 14 by 12, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1041.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 12

Advancing to step 6:
27 divided by 12 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 10412.0
If we take 24 away from 27, we end up 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.

Going ahead to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 10412.2
Deduct 24 from 30 and we're left 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.

Advancing to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10412.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10412.25
Subtracting 0 from 0 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 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10412.25
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 10412.25 with a remainder of 0.0.
