We look at the division of 78657967 by 18 
Let's see how many times 18 fits into 78657967.

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
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

Step 2:
18 goes into 78 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 18

Let's proceed to step 3:
The number 18 fits into 66 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 54 from 66 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 18

Going ahead to step 4:
The number 18 fits into 125 6 times, leaving a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 436.0
If we subtract 108 from 125, we get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 18

Let's proceed to step 5:
177 divided by 18 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 4369.0
If we take 162 away from 177, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 18

On to step 6:
The number 18 fits into 159 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 43698.0
Subtract 144 from 159 to get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 18

Advancing to step 7:
156 divided by 18 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 436988.0
Deduct 144 from 156 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 18

Step 8:
18 goes into 127 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 4369887.0
If we take 126 away from 127, we end up 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.

On to step 9:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4369887.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 18, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4369887.05
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4369887.055
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4369887.055, with a leftover of 0.001.
