815985 divided by 7 
Our goal is to divide 815985 by 7.

Advancing to step 1:
7 goes into 8 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 7

On to step 2:
11 divided by 7 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 4 after subtracting 7 from 11.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Going ahead to step 3:
If we divide 45 by 7, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 116.0
Subtracting 42 from 45 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

Moving on to step 4:
If we divide 39 by 7, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
If we take 35 away from 39, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 7

On to step 5:
The number 7 fits into 48 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 11656.0
Subtracting 42 from 48 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 7

Let's proceed to step 6:
If we divide 65 by 7, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 116569.0
If we subtract 63 from 65, we 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.

Moving on to step 7:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 116569.2
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.

Moving on to step 8:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 116569.28
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 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 116569.285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 116569.2857
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.

On to step 11:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 116569.28571
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.

Going ahead to step 12:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 116569.285714
If we take 28 away from 30, 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.

Going ahead to step 13:
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: 116569.2857142
Deduct 14 from 20 and we're left 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 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 116569.28571428
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.

Our division results in 116569.28571428 with a remaining 4e-09.
