Let's divide 851022 by 15
We want to figure out the number of times 851022 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

Moving on to step 2:
When dividing 85 by 15, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 75 from 85 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 15

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
Deduct 90 from 101 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 15

Let's proceed to step 4:
15 goes into 110 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 567.0
The remainder is 5 after subtracting 105 from 110.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Let's proceed to step 5:
52 divided by 15 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 5673.0
The remainder is 7 after subtracting 45 from 52.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

Going ahead to step 6:
15 can be fit into 72 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 56734.0
Subtracting 60 from 72 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
15 goes into 120 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 56734.8
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

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: 56734.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 56734.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 56734.8 with a balance of 0.0.
