We're dividing 245571 by 12 
We want to figure out the number of times 245571 can be divided by 12.

Advancing to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 12

Moving on to step 2:
24 divided by 12 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Moving on to step 3:
If we divide 5 by 12, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Advancing to step 4:
12 can be fit into 55 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
The remainder is 7 after subtracting 48 from 55.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 12

Moving on to step 5:
When dividing 77 by 12, we get 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 2046.0
The remainder is 5 after subtracting 72 from 77.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 12

Advancing to step 6:
The number 12 fits into 51 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 20464.0
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.

Advancing to step 7:
30 divided by 12 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 20464.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20464.25
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.

Moving on to step 9:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20464.25
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.

Advancing to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20464.25
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.

In conclusion, the division gives 20464.25 with a balance of 0.0.
