12234575 ÷ 424 
Our goal is to divide 12234575 by 424.

Moving on to step 1:
1 divided by 424 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 424

Advancing to step 2:
424 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 424

On to step 3:
The number 424 fits into 122 0 times, leaving a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Include the next digit (3) from the dividend after 122, then repeat: 1223 / 424

Moving on to step 4:
When dividing 1223 by 424, we get 2 with a remainder of 375.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 848 from 1223, we get 375.
Include the next digit (4) from the dividend after 375, then repeat: 3754 / 424

Let's proceed to step 5:
If we divide 3754 by 424, we get 8 and a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 3392 from 3754 leaves us with 362.
Fetch the next digit (5) from the dividend, attach it to 362 and continue: 3625 / 424

Moving on to step 6:
The number 424 fits into 3625 8 times, leaving a remainder of 233.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
Deduct 3392 from 3625 and we're left with 233.
Bring next digit (7) of the dividend behind the 233 and repeat the process: 2337 / 424

Moving on to step 7:
424 goes into 2337 5 times with a remainder of 217.
The number 5 becomes the next digit in our result. 
Result so far: 2885.0
Subtract 2120 from 2337 to get 217.
Take the next digit (5) from the dividend and append it to 217, then repeat: 2175 / 424

Step 8:
2175 divided by 424 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 28855.0
If we subtract 2120 from 2175, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
When dividing 550 by 424, we get 1 with a remainder of 126.
The next digit of our result is 1. 
Result so far: 28855.1
Subtracting 424 from 550 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
424 can be fit into 1260 2 times, resulting in a remainder of 412.
Put 2 as the next digit of the answer. 
Result so far: 28855.12
Subtracting 848 from 1260 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
If we divide 4120 by 424, we get 9 and a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 28855.129
If we subtract 3816 from 4120, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 12:
424 can be fit into 3040 7 times, resulting in a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 28855.1297
If we subtract 2968 from 3040, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
When dividing 720 by 424, we get 1 with a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 28855.12971
If we take 424 away from 720, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 14:
When dividing 2960 by 424, we get 6 with a remainder of 416.
The next digit of our result is 6. 
Result so far: 28855.129716
Deduct 2544 from 2960 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 15:
424 goes into 4160 9 times with a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 28855.1297169
If we take 3816 away from 4160, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 16:
424 can be fit into 3440 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 28855.12971698
If we take 3392 away from 3440, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 28855.12971698, with a leftover of 4.8e-08.
