870353 divided by 7 
We want to figure out the number of times 870353 can be divided by 7.

Going ahead to step 1:
7 goes into 8 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Advancing to step 2:
17 divided by 7 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
If we take 14 away from 17, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 7

Going ahead to step 3:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we take 28 away from 30, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

Advancing to step 4:
If we divide 23 by 7, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1243.0
Subtract 21 from 23 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Let's proceed to step 5:
7 goes into 25 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 12433.0
Deduct 21 from 25 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 7

Step 6:
The number 7 fits into 43 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 124336.0
Subtracting 42 from 43 leaves us 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: 124336.1
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.

Moving on to step 8:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 124336.14
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.

Moving on to step 9:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 124336.142
Subtract 14 from 20 to 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.

Let's proceed to step 10:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 124336.1428
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.

On to step 11:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 124336.14285
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.

On to step 12:
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: 124336.142857
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.

Step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 124336.1428571
If we take 7 away from 10, 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.

Moving on to step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 124336.14285714
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.

The final result is 124336.14285714 with a remainder of 2e-09.
