We look at the division of 862451 by 9 
Let's see how many times 9 fits into 862451.

Going ahead to step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 9

Step 2:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 81 from 86, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Going ahead to step 3:
9 goes into 52 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 45 from 52 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 9

Advancing to step 4:
9 goes into 74 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 958.0
Subtract 72 from 74 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 9

On to step 5:
9 can be fit into 25 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 9582.0
If we take 18 away from 25, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 9

Going ahead to step 6:
If we divide 71 by 9, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 95827.0
Subtract 63 from 71 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 9 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 95827.8
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 95827.88
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 95827.88, and the remainder is 0.008.
