863776 ÷ 7 
We want to figure out the number of times 863776 can be divided by 7.

Moving on to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

Step 2:
16 divided by 7 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 2 after subtracting 14 from 16.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

Going ahead to step 3:
If we divide 23 by 7, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 2 after subtracting 21 from 23.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 7

On to step 4:
When dividing 27 by 7, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1233.0
Deduct 21 from 27 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Moving on to step 5:
When dividing 67 by 7, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12339.0
If we subtract 63 from 67, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 7

On to step 6:
When dividing 46 by 7, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 123396.0
If we subtract 42 from 46, 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 7:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 123396.5
Subtract 35 from 40 to 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.

Advancing to step 8:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 123396.57
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.

Moving on to step 9:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 123396.571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 123396.5714
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 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 123396.57142
Subtracting 14 from 20 leaves us 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.

On to step 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 123396.571428
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 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 123396.5714285
Subtract 35 from 40 to 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.

On to step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 123396.57142857
Deduct 49 from 50 and we're left 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.

In conclusion, the division gives 123396.57142857 with a balance of 1e-09.
