We look at the division of 78981611 by 18 
Our goal is to divide 78981611 by 18.

Let's proceed to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 18

Let's proceed to step 2:
18 can be fit into 78 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 72 from 78 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Moving on to step 3:
The number 18 fits into 69 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 54 from 69 and we're left with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

Going ahead to step 4:
158 divided by 18 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 438.0
Deduct 144 from 158 and we're left with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 18

Going ahead to step 5:
The number 18 fits into 141 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 4387.0
If we take 126 away from 141, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 18

Let's proceed to step 6:
If we divide 156 by 18, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 43878.0
If we take 144 away from 156, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 18

Going ahead to step 7:
When dividing 121 by 18, we get 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 438786.0
If we take 108 away from 121, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 18

Going ahead to step 8:
131 divided by 18 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 4387867.0
The remainder is 5 after subtracting 126 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
18 can be fit into 50 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 4387867.2
Deduct 36 from 50 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4387867.27
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
18 goes into 140 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 4387867.277
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 4387867.277, and the remainder is 0.0014.
