We look at the division of 71349199 by 18 
We want to figure out the number of times 71349199 can be divided by 18.

Going ahead to step 1:
7 divided by 18 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 18

Going ahead to step 2:
The number 18 fits into 71 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 54 from 71, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 18

Going ahead to step 3:
173 divided by 18 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 162 from 173 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 18

Going ahead to step 4:
When dividing 114 by 18, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 396.0
If we take 108 away from 114, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 18

On to step 5:
18 goes into 69 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3963.0
If we take 54 away from 69, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 18

Going ahead to step 6:
If we divide 151 by 18, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 39638.0
Subtract 144 from 151 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 18

On to step 7:
The number 18 fits into 79 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 396384.0
If we subtract 72 from 79, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 18

On to step 8:
When dividing 79 by 18, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 3963844.0
Subtracting 72 from 79 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3963844.3
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.

Step 10:
160 divided by 18 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3963844.38
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.

Moving on to step 11:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3963844.388
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 3963844.388 and a remainder of 0.0016.
