We divide 780343 by 7
We're looking to find how many times 7 goes into 780343.

Going ahead to step 1:
When dividing 7 by 7, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

Step 2:
When dividing 8 by 7, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 7 from 8 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 7

Moving on to step 3:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 7 from 10 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 7

Advancing to step 4:
If we divide 33 by 7, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 1114.0
Subtract 28 from 33 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 7

Moving on to step 5:
The number 7 fits into 54 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 11147.0
If we subtract 49 from 54, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

On to step 6:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 111477.0
Subtracting 49 from 53 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.

Step 7:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 111477.5
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 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 111477.57
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.

Let's proceed to step 9:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 111477.571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 111477.5714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 111477.57142
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.

On 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: 111477.571428
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.

Step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 111477.5714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 111477.57142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 111477.57142857 with a remainder of 1e-09.
