Let's divide 400571 by 25
We want to figure out the number of times 400571 can be divided by 25.

Let's proceed to step 1:
25 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 25

Let's proceed to step 2:
The number 25 fits into 40 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 25 away from 40, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 25

Going ahead to step 3:
The number 25 fits into 150 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 150 from 150 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 25

Moving on to step 4:
25 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 25

Moving on to step 5:
If we divide 57 by 25, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 1602.0
Deduct 50 from 57 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 25

Advancing to step 6:
25 goes into 71 2 times with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 16022.0
The remainder is 21 after subtracting 50 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 25, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 16022.8
Subtracting 200 from 210 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 16022.84
Deduct 100 from 100 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.

On to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16022.84
Deduct 0 from 0 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.

Let's proceed to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16022.84
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.

Our division results in 16022.84 with a remaining 0.0.
