We're dividing 87161813 by 9 
Let's see how many times 9 fits into 87161813.

Moving on to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 9

Let's proceed to step 2:
When dividing 87 by 9, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 81 from 87, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 9

Step 3:
When dividing 61 by 9, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 7 after subtracting 54 from 61.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 9

On to step 4:
The number 9 fits into 76 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 968.0
The remainder is 4 after subtracting 72 from 76.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 9

Step 5:
If we divide 41 by 9, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 9684.0
Subtracting 36 from 41 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 9

Moving on to step 6:
9 can be fit into 58 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 96846.0
Subtracting 54 from 58 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 9

Step 7:
If we divide 41 by 9, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 968464.0
Subtract 36 from 41 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 9

Advancing to step 8:
9 can be fit into 53 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 9684645.0
Deduct 45 from 53 and we're left 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.

Moving on to step 9:
If we divide 80 by 9, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 9684645.8
Deduct 72 from 80 and we're left 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.

Step 10:
When dividing 80 by 9, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 9684645.88
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.

Our division results in 9684645.88 with a remaining 0.008.
