12859028 ÷ 433 
Our goal is to divide 12859028 by 433.

Let's proceed to step 1:
If we divide 1 by 433, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 433

Step 2:
The number 433 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 433

Moving on to step 3:
If we divide 128 by 433, we get 0 and a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Grab the next digit (5) from the dividend, add it to 128, then carry on: 1285 / 433

Moving on to step 4:
433 goes into 1285 2 times with a remainder of 419.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 866 from 1285 leaves us with 419.
Take the next digit (9) from the dividend and append it to 419, then repeat: 4199 / 433

Step 5:
The number 433 fits into 4199 9 times, leaving a remainder of 302.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 3897 from 4199 leaves us with 302.
Append the next digit (0) from the dividend to 302 and continue with: 3020 / 433

Moving on to step 6:
If we divide 3020 by 433, we get 6 and a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 296.0
If we take 2598 away from 3020, we end up with 422.
Fetch the next digit (2) from the dividend, attach it to 422 and continue: 4222 / 433

On to step 7:
If we divide 4222 by 433, we get 9 and a remainder of 325.
The next digit of our result is 9. 
Result so far: 2969.0
Deduct 3897 from 4222 and we're left with 325.
Grab the next digit (8) from the dividend, add it to 325, then carry on: 3258 / 433

Step 8:
3258 divided by 433 is 7 with a remainder of 227.
Record the quotient 7 as the next digit in the result. 
Result so far: 29697.0
Subtracting 3031 from 3258 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
433 can be fit into 2270 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 29697.5
If we subtract 2165 from 2270, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 10:
If we divide 1050 by 433, we get 2 and a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 29697.52
Deduct 866 from 1050 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 11:
1840 divided by 433 is 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 29697.524
Subtract 1732 from 1840 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
When dividing 1080 by 433, we get 2 with a remainder of 214.
The next digit of our result is 2. 
Result so far: 29697.5242
Subtracting 866 from 1080 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
The number 433 fits into 2140 4 times, leaving a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 29697.52424
If we subtract 1732 from 2140, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 14:
If we divide 4080 by 433, we get 9 and a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 29697.524249
Subtracting 3897 from 4080 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 15:
1830 divided by 433 is 4 with a remainder of 98.
The next digit of our result is 4. 
Result so far: 29697.5242494
Subtract 1732 from 1830 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
If we divide 980 by 433, we get 2 and a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 29697.52424942
The remainder is 114 after subtracting 866 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 29697.52424942 with a remainder of 1.14e-07.
