We're dividing 12543748 by 433 
We want to divide 12543748 by 433.

Advancing to step 1:
433 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 433

On to step 2:
If we divide 12 by 433, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 433

Step 3:
If we divide 125 by 433, we get 0 and a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Fetch the next digit (4) from the dividend, attach it to 125 and continue: 1254 / 433

Moving on to step 4:
The number 433 fits into 1254 2 times, leaving a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 866 from 1254 leaves us with 388.
Fetch the next digit (3) from the dividend, attach it to 388 and continue: 3883 / 433

On to step 5:
If we divide 3883 by 433, we get 8 and a remainder of 419.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 3464 from 3883 and we're left with 419.
Append the next digit (7) from the dividend to 419 and continue with: 4197 / 433

Moving on to step 6:
The number 433 fits into 4197 9 times, leaving a remainder of 300.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 3897 away from 4197, we end up with 300.
Append the next digit (4) from the dividend to 300 and continue with: 3004 / 433

Moving on to step 7:
3004 divided by 433 is 6 with a remainder of 406.
The number 6 becomes the next digit in our result. 
Result so far: 2896.0
The remainder is 406 after subtracting 2598 from 3004.
Fetch the next digit (8) from the dividend, attach it to 406 and continue: 4068 / 433

On to step 8:
If we divide 4068 by 433, we get 9 and a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 28969.0
Subtracting 3897 from 4068 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 9:
If we divide 1710 by 433, we get 3 and a remainder of 411.
The next digit of our result is 3. 
Result so far: 28969.3
If we take 1299 away from 1710, we end up with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 10:
433 goes into 4110 9 times with a remainder of 213.
Write down 9 as next digit of the result. 
Result so far: 28969.39
Subtract 3897 from 4110 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 11:
When dividing 2130 by 433, we get 4 with a remainder of 398.
Use 4 as the next digit of our solution. 
Result so far: 28969.394
If we subtract 1732 from 2130, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 12:
3980 divided by 433 is 9 with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 28969.3949
If we take 3897 away from 3980, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
433 goes into 830 1 times with a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 28969.39491
Deduct 433 from 830 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 14:
If we divide 3970 by 433, we get 9 and a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 28969.394919
Deduct 3897 from 3970 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 15:
If we divide 730 by 433, we get 1 and a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 28969.3949191
Subtract 433 from 730 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 16:
433 can be fit into 2970 6 times, resulting in a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 28969.39491916
Subtract 2598 from 2970 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The quotient of the division is 28969.39491916, and the remainder is 3.72e-07.
