79581198 divided by 18 
Our goal is to divide 79581198 by 18.

Moving on to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 18

On to step 2:
The number 18 fits into 79 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 72 from 79 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 18

Advancing to step 3:
The number 18 fits into 75 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 72 from 75, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

Moving on to step 4:
The number 18 fits into 38 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 442.0
Subtracting 36 from 38 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 18

Step 5:
The number 18 fits into 21 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 4421.0
If we subtract 18 from 21, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 18

Let's proceed to step 6:
31 divided by 18 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 44211.0
Deduct 18 from 31 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 18

Step 7:
18 goes into 139 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 442117.0
If we subtract 126 from 139, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 18

On to step 8:
If we divide 138 by 18, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 4421177.0
Subtracting 126 from 138 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 4421177.6
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 18, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 4421177.66
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 4421177.66 and a remainder of 0.012.
