We look at the division of 12346659 by 725 
We want to divide 12346659 by 725.

On to step 1:
The number 725 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 725

Moving on to step 2:
If we divide 12 by 725, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 725

Moving on to step 3:
725 can be fit into 123 0 times, resulting in a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Append the next digit (4) from the dividend to 123 and continue with: 1234 / 725

On to step 4:
725 can be fit into 1234 1 times, resulting in a remainder of 509.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 725 from 1234, we get 509.
Bring next digit (6) of the dividend behind the 509 and repeat the process: 5096 / 725

On to step 5:
725 can be fit into 5096 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 5075 from 5096 to get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 725

Step 6:
725 can be fit into 216 0 times, resulting in a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 170.0
Deduct 0 from 216 and we're left with 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 725

Step 7:
2165 divided by 725 is 2 with a remainder of 715.
Write down 2 as next digit of the result. 
Result so far: 1702.0
The remainder is 715 after subtracting 1450 from 2165.
Fetch the next digit (9) from the dividend, attach it to 715 and continue: 7159 / 725

Going ahead to step 8:
The number 725 fits into 7159 9 times, leaving a remainder of 634.
Use 9 as the next digit of our solution. 
Result so far: 17029.0
Subtracting 6525 from 7159 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 9:
When dividing 6340 by 725, we get 8 with a remainder of 540.
Use 8 as the next digit of our solution. 
Result so far: 17029.8
If we take 5800 away from 6340, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
5400 divided by 725 is 7 with a remainder of 325.
The next digit of our result is 7. 
Result so far: 17029.87
If we take 5075 away from 5400, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 11:
725 goes into 3250 4 times with a remainder of 350.
The number 4 becomes the next digit in our result. 
Result so far: 17029.874
Subtract 2900 from 3250 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
725 can be fit into 3500 4 times, resulting in a remainder of 600.
Put 4 as the next digit of the answer. 
Result so far: 17029.8744
Subtracting 2900 from 3500 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 17029.8744 with a remainder of 0.006.
