We look at the division of 800809 by 7 
We want to figure out the number of times 800809 can be divided by 7.

Going ahead to step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 7

Advancing to step 2:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 3 after subtracting 7 from 10.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 7

Moving on to step 3:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Deduct 28 from 30 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 7

Step 4:
If we divide 28 by 7, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1144.0
If we take 28 away from 28, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 7

Let's proceed to step 5:
If we divide 0 by 7, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11440.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 7

On to step 6:
7 goes into 9 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 114401.0
If we take 7 away from 9, we end up 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.

Advancing to step 7:
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: 114401.2
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.

On to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 114401.28
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.

Step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 114401.285
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 10:
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: 114401.2857
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.

Let's proceed to step 11:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 114401.28571
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.

Step 12:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 114401.285714
Deduct 28 from 30 and we're left 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.

Step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 114401.2857142
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.

Step 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 114401.28571428
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.

The final result is 114401.28571428 with a remainder of 4e-09.
