We're dividing 78840 by 7 
Let's see how many times 7 fits into 78840.

Let's proceed to step 1:
7 divided by 7 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 7

On to step 2:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 7 from 8 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 7

Step 3:
7 goes into 18 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 14 away from 18, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 7

Advancing to step 4:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1126.0
If we take 42 away from 44, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

Going ahead to step 5:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 11262.0
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11262.8
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11262.85
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11262.857
If we subtract 49 from 50, we get 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:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11262.8571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 11262.85714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 11262.857142
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 11262.8571428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11262.85714285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 11262.85714285 with a remainder of 5e-09.
