961870 divided by 15 
We want to figure out the number of times 961870 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 15

Going ahead to step 2:
96 divided by 15 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 90 from 96 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 15

Step 3:
If we divide 61 by 15, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 60 from 61 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Moving on to step 4:
If we divide 18 by 15, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Deduct 15 from 18 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 15

Going ahead to step 5:
When dividing 37 by 15, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 6412.0
Subtracting 30 from 37 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 15

Advancing to step 6:
If we divide 70 by 15, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 64124.0
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 64124.6
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 64124.66
Subtract 90 from 100 to get 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 64124.66 with a remainder of 0.01.
