We're dividing 54304231 by 423 
We're looking to find how many times 423 goes into 54304231.

On to step 1:
5 divided by 423 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 423

Step 2:
54 divided by 423 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 423

Let's proceed to step 3:
423 can be fit into 543 1 times, resulting in a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 120 after subtracting 423 from 543.
Take the next digit (0) from the dividend and append it to 120, then repeat: 1200 / 423

Step 4:
423 goes into 1200 2 times with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 846 from 1200 leaves us with 354.
Take the next digit (4) from the dividend and append it to 354, then repeat: 3544 / 423

Going ahead to step 5:
If we divide 3544 by 423, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 128.0
The remainder is 160 after subtracting 3384 from 3544.
Bring next digit (2) of the dividend behind the 160 and repeat the process: 1602 / 423

Step 6:
1602 divided by 423 is 3 with a remainder of 333.
Put 3 as the next digit of the answer. 
Result so far: 1283.0
If we take 1269 away from 1602, we end up with 333.
Bring next digit (3) of the dividend behind the 333 and repeat the process: 3333 / 423

Moving on to step 7:
423 goes into 3333 7 times with a remainder of 372.
Record the quotient 7 as the next digit in the result. 
Result so far: 12837.0
The remainder is 372 after subtracting 2961 from 3333.
Bring next digit (1) of the dividend behind the 372 and repeat the process: 3721 / 423

Going ahead to step 8:
423 can be fit into 3721 8 times, resulting in a remainder of 337.
The next digit of our result is 8. 
Result so far: 128378.0
Subtract 3384 from 3721 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 9:
423 goes into 3370 7 times with a remainder of 409.
Use 7 as the next digit of our solution. 
Result so far: 128378.7
Deduct 2961 from 3370 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 10:
The number 423 fits into 4090 9 times, leaving a remainder of 283.
Record the quotient 9 as the next digit in the result. 
Result so far: 128378.79
If we subtract 3807 from 4090, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 11:
When dividing 2830 by 423, we get 6 with a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 128378.796
Subtract 2538 from 2830 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 12:
423 can be fit into 2920 6 times, resulting in a remainder of 382.
The next digit of our result is 6. 
Result so far: 128378.7966
If we take 2538 away from 2920, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

After the division, we end up with 128378.7966 and a remainder of 0.00382.
