Let's divide 251906 by 15
Let's see how many times 15 fits into 251906.

Step 1:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 15

Advancing to step 2:
When dividing 25 by 15, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 15 from 25 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 15

Going ahead to step 3:
When dividing 101 by 15, we get 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 90 away from 101, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 15

Let's proceed to step 4:
If we divide 119 by 15, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Subtracting 105 from 119 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 15

Moving on to step 5:
140 divided by 15 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1679.0
If we take 135 away from 140, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 15

Step 6:
56 divided by 15 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 16793.0
Deduct 45 from 56 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 16793.7
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 16793.73
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 16793.733
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 16793.733 with a remainder of 0.0005.
