Let's divide 839879 by 7
Our goal is to divide 839879 by 7.

Advancing to step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 8 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

Step 2:
When dividing 13 by 7, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 7 from 13 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 7

Advancing to step 3:
When dividing 69 by 7, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 6 after subtracting 63 from 69.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Going ahead to step 4:
7 can be fit into 68 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 1199.0
Subtracting 63 from 68 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 7

Let's proceed to step 5:
7 goes into 57 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 11998.0
The remainder is 1 after subtracting 56 from 57.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 7

Advancing to step 6:
7 goes into 19 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 119982.0
If we take 14 away from 19, 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 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 119982.7
If we take 49 away from 50, we end up 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 8:
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: 119982.71
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.

On to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 119982.714
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.

Moving on to step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 119982.7142
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.

Moving on to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 119982.71428
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 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 119982.714285
Subtracting 35 from 40 leaves us 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 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 119982.7142857
The remainder is 1 after subtracting 49 from 50.
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 14:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 119982.71428571
If we subtract 7 from 10, we 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.

Our division results in 119982.71428571 with a remaining 3e-09.
