We're dividing 84061791 by 18 
We want to divide 84061791 by 18.

Step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 18

Advancing to step 2:
If we divide 84 by 18, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 72 from 84 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 18

Let's proceed to step 3:
18 goes into 120 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 12 after subtracting 108 from 120.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 18

On to step 4:
18 goes into 126 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 467.0
Deduct 126 from 126 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 18

Advancing to step 5:
18 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 4670.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 18

On to step 6:
When dividing 17 by 18, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 46700.0
Subtract 0 from 17 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 18

Let's proceed to step 7:
When dividing 179 by 18, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 467009.0
If we subtract 162 from 179, we get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 18

Moving on to step 8:
When dividing 171 by 18, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 4670099.0
Subtracting 162 from 171 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
18 can be fit into 90 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4670099.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 18 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4670099.5
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 11:
0 divided by 18 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4670099.5
If we take 0 away from 0, 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.

The final result is 4670099.5 with a remainder of 0.0.
