872870 divided by 7 
We want to divide 872870 by 7.

Moving on to step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 7

Moving on to step 2:
17 divided by 7 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 14 from 17 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 7

Advancing to step 3:
32 divided by 7 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 28 from 32 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Step 4:
When dividing 48 by 7, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1246.0
The remainder is 6 after subtracting 42 from 48.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 7

Let's proceed to step 5:
7 goes into 67 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 12469.0
Subtracting 63 from 67 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 7

Let's proceed to step 6:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 124695.0
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.

Step 7:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 124695.7
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.

Step 8:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 124695.71
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.

Advancing to step 9:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 124695.714
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.

On to step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 124695.7142
If we subtract 14 from 20, we 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.

Advancing to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 124695.71428
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.

Let's proceed to step 12:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 124695.714285
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 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 124695.7142857
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.

Going ahead to step 14:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 124695.71428571
Deduct 7 from 10 and we're left 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.

The final outcome is 124695.71428571, with a leftover of 3e-09.
