We look at the division of 778872 by 7 
We want to figure out the number of times 778872 can be divided by 7.

Advancing to step 1:
When dividing 7 by 7, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

Advancing to step 2:
7 goes into 7 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 7 from 7, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 7

Moving on to step 3:
7 goes into 8 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
The remainder is 1 after subtracting 7 from 8.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Let's proceed to step 4:
18 divided by 7 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1112.0
Subtracting 14 from 18 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Advancing to step 5:
7 can be fit into 47 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 11126.0
Deduct 42 from 47 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 7

Going ahead to step 6:
When dividing 52 by 7, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 111267.0
If we take 49 away from 52, 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.

Advancing to step 7:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 111267.4
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.

Going ahead to step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 111267.42
If we take 14 away from 20, we end up 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 9:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 111267.428
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.

Step 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 111267.4285
Deduct 35 from 40 and we're left 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.

Moving on to step 11:
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: 111267.42857
Deduct 49 from 50 and we're left 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.

Step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 111267.428571
The remainder is 3 after subtracting 7 from 10.
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 13:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 111267.4285714
If we take 28 away from 30, we end up 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 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 111267.42857142
If we take 14 away from 20, we end up 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.

After the division, we end up with 111267.42857142 and a remainder of 6e-09.
