Let's divide 780415 by 7
We want to divide 780415 by 7.

Step 1:
7 goes into 7 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 7

Advancing to 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
If we subtract 7 from 8, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 7

Step 3:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Subtract 7 from 10 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 7

Step 4:
7 can be fit into 34 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1114.0
Subtract 28 from 34 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 7

Moving on to step 5:
The number 7 fits into 61 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 11148.0
The remainder is 5 after subtracting 56 from 61.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 7

Going ahead to step 6:
If we divide 55 by 7, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 111487.0
The remainder is 6 after subtracting 49 from 55.
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 7:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 111487.8
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
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: 111487.85
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 111487.857
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.

Let's proceed to step 10:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 111487.8571
Subtracting 7 from 10 leaves us 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.

On to step 11:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 111487.85714
Subtracting 28 from 30 leaves us 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.

On to step 12:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 111487.857142
Subtract 14 from 20 to 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.

Going ahead to step 13:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 111487.8571428
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.

Advancing to step 14:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 111487.85714285
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 outcome is 111487.85714285, with a leftover of 5e-09.
