45205 ÷ 12 
We want to divide 45205 by 12.

Let's proceed to step 1:
12 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Let's proceed to step 2:
45 divided by 12 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 36 away from 45, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Advancing to step 3:
The number 12 fits into 92 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 8 after subtracting 84 from 92.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

Going ahead to step 4:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we take 72 away from 80, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 12

Going ahead to step 5:
If we divide 85 by 12, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 3767.0
Deduct 84 from 85 and we're left with 1.
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:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3767.0
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.

Let's proceed to step 7:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3767.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3767.083
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3767.0833
If we take 36 away from 40, we end up 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.

In conclusion, the division gives 3767.0833 with a balance of 4e-05.
