879789 divided by 7 
Let's see how many times 7 fits into 879789.

Let's proceed to step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Step 2:
17 divided by 7 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 3 after subtracting 14 from 17.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 7

Step 3:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 35 from 39 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 7

Advancing to step 4:
If we divide 47 by 7, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 1256.0
The remainder is 5 after subtracting 42 from 47.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

On to step 5:
58 divided by 7 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 12568.0
Deduct 56 from 58 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Advancing to step 6:
7 goes into 29 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 125684.0
If we take 28 away from 29, 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.

Going ahead to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 125684.1
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.

Advancing to step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 125684.14
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.

Step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 125684.142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 125684.1428
Deduct 56 from 60 and we're left 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 11:
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: 125684.14285
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.

Let's proceed to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 125684.142857
Subtract 49 from 50 to 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.

On to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 125684.1428571
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 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 125684.14285714
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.

After the division, we end up with 125684.14285714 and a remainder of 2e-09.
