We divide 379640 by 25
Let's see how many times 25 fits into 379640.

Going ahead to step 1:
25 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 25

Moving on to step 2:
If we divide 37 by 25, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 25 from 37 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 25

Moving on to step 3:
25 can be fit into 129 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 125 from 129 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 25

Going ahead to step 4:
The number 25 fits into 46 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 25 from 46, we get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 25

Going ahead to step 5:
The number 25 fits into 214 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 1518.0
Subtracting 200 from 214 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 25

Step 6:
If we divide 140 by 25, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15185.0
Deduct 125 from 140 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 25 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 15185.6
The remainder is 0 after subtracting 150 from 150.
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 8:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15185.6
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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15185.6
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.

The final result is 15185.6 with a remainder of 0.0.
