Let's divide 851610 by 15
We want to figure out the number of times 851610 can be divided by 15.

Moving on to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

Let's proceed to step 2:
When dividing 85 by 15, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 85, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

On to step 3:
When dividing 101 by 15, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 90 from 101 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 15

On to step 4:
If we divide 116 by 15, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 567.0
If we take 105 away from 116, we end up with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 15

Going ahead to step 5:
15 can be fit into 111 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 5677.0
The remainder is 6 after subtracting 105 from 111.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 15

Advancing to step 6:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 56774.0
If we take 60 away from 60, we end up 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.

Going ahead to step 7:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56774.0
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.

Moving on to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56774.0
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.

The final result is 56774.0 with a remainder of 0.0.
