We look at the division of 25515964 by 429 
Our goal is to divide 25515964 by 429.

Let's proceed to step 1:
429 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 429

Step 2:
When dividing 25 by 429, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 429

Going ahead to step 3:
429 can be fit into 255 0 times, resulting in a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 255, we get 255.
Include the next digit (1) from the dividend after 255, then repeat: 2551 / 429

On to step 4:
429 goes into 2551 5 times with a remainder of 406.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 406 after subtracting 2145 from 2551.
Fetch the next digit (5) from the dividend, attach it to 406 and continue: 4065 / 429

Let's proceed to step 5:
4065 divided by 429 is 9 with a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Deduct 3861 from 4065 and we're left with 204.
Bring next digit (9) of the dividend behind the 204 and repeat the process: 2049 / 429

Advancing to step 6:
2049 divided by 429 is 4 with a remainder of 333.
The next digit of our result is 4. 
Result so far: 594.0
Subtracting 1716 from 2049 leaves us with 333.
Append the next digit (6) from the dividend to 333 and continue with: 3336 / 429

Step 7:
When dividing 3336 by 429, we get 7 with a remainder of 333.
Write down 7 as next digit of the result. 
Result so far: 5947.0
The remainder is 333 after subtracting 3003 from 3336.
Bring next digit (4) of the dividend behind the 333 and repeat the process: 3334 / 429

Going ahead to step 8:
429 goes into 3334 7 times with a remainder of 331.
The number 7 becomes the next digit in our result. 
Result so far: 59477.0
Deduct 3003 from 3334 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 9:
When dividing 3310 by 429, we get 7 with a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 59477.7
The remainder is 307 after subtracting 3003 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 10:
The number 429 fits into 3070 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 59477.77
If we take 3003 away from 3070, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 59477.77, and the remainder is 0.067.
