We're dividing 841623 by 18 
We want to divide 841623 by 18.

Advancing to step 1:
18 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
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 18

Advancing to step 2:
18 can be fit into 84 4 times, resulting in 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.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 18

Going ahead to step 3:
121 divided by 18 is 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 108 from 121 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 18

Moving on to step 4:
When dividing 136 by 18, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 467.0
Deduct 126 from 136 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 18

Moving on to step 5:
18 goes into 102 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 4675.0
The remainder is 12 after subtracting 90 from 102.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 18

On to step 6:
When dividing 123 by 18, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 46756.0
If we subtract 108 from 123, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 46756.8
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
18 goes into 60 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 46756.83
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 46756.833
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 46756.833, with a leftover of 0.0006.
