6231255 ÷ 429 
We want to divide 6231255 by 429.

Let's proceed to step 1:
429 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 429

Step 2:
62 divided by 429 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 429

On to step 3:
The number 429 fits into 623 1 times, leaving a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 429 away from 623, we end up with 194.
Include the next digit (1) from the dividend after 194, then repeat: 1941 / 429

On to step 4:
429 goes into 1941 4 times with a remainder of 225.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1716 from 1941 leaves us with 225.
Append the next digit (2) from the dividend to 225 and continue with: 2252 / 429

Moving on to step 5:
The number 429 fits into 2252 5 times, leaving a remainder of 107.
The next digit of our result is 5. 
Result so far: 145.0
Deduct 2145 from 2252 and we're left with 107.
Take the next digit (5) from the dividend and append it to 107, then repeat: 1075 / 429

Advancing to step 6:
The number 429 fits into 1075 2 times, leaving a remainder of 217.
Use 2 as the next digit of our solution. 
Result so far: 1452.0
Subtracting 858 from 1075 leaves us with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 429

Moving on to step 7:
When dividing 2175 by 429, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14525.0
Subtract 2145 from 2175 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 429 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 14525.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
If we divide 3000 by 429, we get 6 and a remainder of 426.
The next digit of our result is 6. 
Result so far: 14525.06
Subtract 2574 from 3000 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 10:
If we divide 4260 by 429, we get 9 and a remainder of 399.
Record the quotient 9 as the next digit in the result. 
Result so far: 14525.069
The remainder is 399 after subtracting 3861 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 11:
429 can be fit into 3990 9 times, resulting in a remainder of 129.
The next digit of our result is 9. 
Result so far: 14525.0699
Subtracting 3861 from 3990 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 14525.0699, with a leftover of 0.00129.
