Let's divide 78380911 by 270
We want to divide 78380911 by 270.

Step 1:
270 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 270

Moving on to step 2:
When dividing 78 by 270, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 270

On to step 3:
783 divided by 270 is 2 with a remainder of 243.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 540 from 783 to get 243.
Append the next digit (8) from the dividend to 243 and continue with: 2438 / 270

On to step 4:
If we divide 2438 by 270, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 8 after subtracting 2430 from 2438.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 270

Going ahead to step 5:
If we divide 80 by 270, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 290.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 270

Advancing to step 6:
270 can be fit into 809 2 times, resulting in a remainder of 269.
Use 2 as the next digit of our solution. 
Result so far: 2902.0
If we take 540 away from 809, we end up with 269.
Include the next digit (1) from the dividend after 269, then repeat: 2691 / 270

Going ahead to step 7:
270 goes into 2691 9 times with a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 29029.0
If we take 2430 away from 2691, we end up with 261.
Fetch the next digit (1) from the dividend, attach it to 261 and continue: 2611 / 270

Step 8:
When dividing 2611 by 270, we get 9 with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 290299.0
If we take 2430 away from 2611, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 9:
When dividing 1810 by 270, we get 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 290299.6
Subtract 1620 from 1810 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
If we divide 1900 by 270, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 290299.67
Deduct 1890 from 1900 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.

Step 11:
The number 270 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 290299.67
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
When dividing 1000 by 270, we get 3 with a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 290299.6703
If we take 810 away from 1000, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 13:
270 goes into 1900 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 290299.67037
If we take 1890 away from 1900, 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 14:
When dividing 100 by 270, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 290299.67037
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
When dividing 1000 by 270, we get 3 with a remainder of 190.
The next digit of our result is 3. 
Result so far: 290299.6703703
The remainder is 190 after subtracting 810 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 16:
If we divide 1900 by 270, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 290299.67037037
Subtracting 1890 from 1900 leaves us 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.

Our division results in 290299.67037037 with a remaining 1e-08.
