607861 divided by 15 
Let's see how many times 15 fits into 607861.

Step 1:
15 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 15

Moving on to step 2:
When dividing 60 by 15, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 60 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 15

Moving on to step 3:
15 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Going ahead to step 4:
15 goes into 78 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Subtracting 75 from 78 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 15

Going ahead to step 5:
36 divided by 15 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 4052.0
Deduct 30 from 36 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 15

Step 6:
15 can be fit into 61 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 40524.0
The remainder is 1 after subtracting 60 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 15, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 40524.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 40524.06
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 40524.066
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 40524.066 with a remainder of 0.001.
