We divide 71781775 by 18
We want to divide 71781775 by 18.

Step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 18

Moving on to step 2:
18 goes into 71 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 54 from 71 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 18

Let's proceed to step 3:
The number 18 fits into 177 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 162 from 177 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 18

Let's proceed to step 4:
The number 18 fits into 158 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we take 144 away from 158, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 18

Advancing to step 5:
When dividing 141 by 18, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 3987.0
If we subtract 126 from 141, we get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 18

Moving on to step 6:
157 divided by 18 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 39878.0
Subtract 144 from 157 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 18

On to step 7:
If we divide 137 by 18, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 398787.0
If we subtract 126 from 137, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 18

Advancing to step 8:
18 can be fit into 115 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 3987876.0
If we take 108 away from 115, we end up 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.

Going ahead to step 9:
18 goes into 70 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3987876.3
Subtract 54 from 70 to 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.

Moving on to step 10:
160 divided by 18 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3987876.38
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.

On to step 11:
If we divide 160 by 18, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3987876.388
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.

The final result is 3987876.388 with a remainder of 0.0016.
