Let's divide 870575 by 7
We want to figure out the number of times 870575 can be divided by 7.

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
Deduct 7 from 8 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 7

Let's proceed to step 2:
7 goes into 17 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 14 from 17 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 7

Step 3:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 124.0
The remainder is 2 after subtracting 28 from 30.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 7

Going ahead to step 4:
If we divide 25 by 7, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1243.0
The remainder is 4 after subtracting 21 from 25.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 7

On to step 5:
The number 7 fits into 47 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 12436.0
Deduct 42 from 47 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 7

Let's proceed to step 6:
When dividing 55 by 7, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 124367.0
Subtract 49 from 55 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.

On to step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 124367.8
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 124367.85
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.

Going ahead to step 9:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 124367.857
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.

Advancing to step 10:
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: 124367.8571
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.

Advancing to step 11:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 124367.85714
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 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 124367.857142
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.

Advancing to step 13:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 124367.8571428
If we subtract 56 from 60, we get 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 14:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 124367.85714285
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.

Our division results in 124367.85714285 with a remaining 5e-09.
