We're dividing 346720 by 25 
We want to divide 346720 by 25.

Let's proceed to step 1:
25 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 25

Let's proceed to step 2:
34 divided by 25 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 25 from 34, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 25

Moving on to step 3:
25 goes into 96 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 75 from 96 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 25

Going ahead to step 4:
When dividing 217 by 25, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 138.0
Subtract 200 from 217 to get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 25

Step 5:
25 goes into 172 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 1386.0
The remainder is 22 after subtracting 150 from 172.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 25

Advancing to step 6:
220 divided by 25 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 13868.0
Deduct 200 from 220 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 13868.8
If we subtract 200 from 200, we 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.

On to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13868.8
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:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 13868.8
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 outcome is 13868.8, with a leftover of 0.0.
