We're dividing 20123412 by 462 
We're looking to find how many times 462 goes into 20123412.

Advancing to step 1:
2 divided by 462 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 462

Going ahead to step 2:
The number 462 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 462

On to step 3:
The number 462 fits into 201 0 times, leaving a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Include the next digit (2) from the dividend after 201, then repeat: 2012 / 462

On to step 4:
462 can be fit into 2012 4 times, resulting in a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1848 from 2012 and we're left with 164.
Bring next digit (3) of the dividend behind the 164 and repeat the process: 1643 / 462

Let's proceed to step 5:
462 goes into 1643 3 times with a remainder of 257.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 1386 from 1643 and we're left with 257.
Append the next digit (4) from the dividend to 257 and continue with: 2574 / 462

Going ahead to step 6:
When dividing 2574 by 462, we get 5 with a remainder of 264.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
If we take 2310 away from 2574, we end up with 264.
Take the next digit (1) from the dividend and append it to 264, then repeat: 2641 / 462

Let's proceed to step 7:
2641 divided by 462 is 5 with a remainder of 331.
Put 5 as the next digit of the answer. 
Result so far: 4355.0
If we subtract 2310 from 2641, we get 331.
Include the next digit (2) from the dividend after 331, then repeat: 3312 / 462

Going ahead to step 8:
If we divide 3312 by 462, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 43557.0
The remainder is 78 after subtracting 3234 from 3312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
462 can be fit into 780 1 times, resulting in a remainder of 318.
Write down 1 as next digit of the result. 
Result so far: 43557.1
Subtract 462 from 780 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 10:
462 goes into 3180 6 times with a remainder of 408.
Use 6 as the next digit of our solution. 
Result so far: 43557.16
The remainder is 408 after subtracting 2772 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 11:
If we divide 4080 by 462, we get 8 and a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 43557.168
If we subtract 3696 from 4080, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 462, we get 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 43557.1688
If we take 3696 away from 3840, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 43557.1688 and a remainder of 0.00144.
