We divide 340990 by 25
Let's see how many times 25 fits into 340990.

Moving on to step 1:
25 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 25

On to step 2:
34 divided by 25 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 25 from 34 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 25

Going ahead to step 3:
The number 25 fits into 90 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 75 from 90, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 25

Going ahead to step 4:
25 can be fit into 159 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 150 from 159 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 25

On to step 5:
25 can be fit into 99 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1363.0
If we take 75 away from 99, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 25

Advancing to step 6:
25 goes into 240 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 13639.0
Subtracting 225 from 240 leaves us 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:
When dividing 150 by 25, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 13639.6
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.

Moving on to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13639.6
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.

Step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13639.6
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.

Our division results in 13639.6 with a remaining 0.0.
