We divide 641428 by 25
We're looking to find how many times 25 goes into 641428.

Advancing to step 1:
6 divided by 25 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 25

Advancing to step 2:
When dividing 64 by 25, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 50 away from 64, we end up with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 25

Going ahead to step 3:
141 divided by 25 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 125 from 141, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 25

Let's proceed to step 4:
25 goes into 164 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 256.0
Deduct 150 from 164 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 25

Going ahead to step 5:
The number 25 fits into 142 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 2565.0
Deduct 125 from 142 and we're left with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 25

Moving on to step 6:
25 goes into 178 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 25657.0
Subtracting 175 from 178 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 25 fits into 30 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 25657.1
The remainder is 5 after subtracting 25 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 25 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 25657.12
Deduct 50 from 50 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25657.12
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25657.12
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 25657.12, and the remainder is 0.0.
