We look at the division of 68471917 by 18 
Our goal is to divide 68471917 by 18.

Step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Going ahead to step 2:
68 divided by 18 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 54 from 68 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 18

Going ahead to step 3:
The number 18 fits into 144 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 0 after subtracting 144 from 144.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 18

Moving on to step 4:
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: 380.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 18

Moving on to step 5:
When dividing 71 by 18, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3803.0
The remainder is 17 after subtracting 54 from 71.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 18

Going ahead to step 6:
If we divide 179 by 18, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 38039.0
Deduct 162 from 179 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 18

Going ahead to step 7:
The number 18 fits into 171 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 380399.0
The remainder is 9 after subtracting 162 from 171.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 18

Step 8:
The number 18 fits into 97 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 3803995.0
Subtract 90 from 97 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
18 goes into 70 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3803995.3
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3803995.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3803995.388
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3803995.388, with a leftover of 0.0016.
