791245 ÷ 18 
We want to divide 791245 by 18.

Going ahead to step 1:
18 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 18

Moving on to step 2:
18 can be fit into 79 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 79, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Step 3:
71 divided by 18 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 54 from 71 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 18

On to step 4:
When dividing 172 by 18, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 439.0
If we subtract 162 from 172, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 18

On to step 5:
18 goes into 104 5 times with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 4395.0
Subtract 90 from 104 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 18

On to step 6:
145 divided by 18 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 43958.0
Deduct 144 from 145 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 18, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43958.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
18 goes into 100 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 43958.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 43958.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 43958.055 and a remainder of 0.001.
