We look at the division of 7879798 by 7 
We're looking to find how many times 7 goes into 7879798.

Advancing to step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

On to step 2:
7 goes into 8 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 1 after subtracting 7 from 8.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

On to step 3:
17 divided by 7 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 112.0
Deduct 14 from 17 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 7

Going ahead to step 4:
If we divide 39 by 7, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 1125.0
The remainder is 4 after subtracting 35 from 39.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 7

Going ahead to step 5:
If we divide 47 by 7, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 11256.0
Deduct 42 from 47 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 7

Let's proceed to step 6:
If we divide 59 by 7, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 112568.0
Deduct 56 from 59 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 7

Step 7:
The number 7 fits into 38 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 1125685.0
Subtract 35 from 38 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.

Advancing to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 1125685.4
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 9:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 1125685.42
Subtracting 14 from 20 leaves us 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 10:
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: 1125685.428
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.

Moving on to step 11:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1125685.4285
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.

Moving on to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1125685.42857
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.

Advancing to step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1125685.428571
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.

Let's proceed to step 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1125685.4285714
Subtract 28 from 30 to get 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 15:
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: 1125685.42857142
Subtracting 14 from 20 leaves us 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.

The final result is 1125685.42857142 with a remainder of 6e-09.
