863436 divided by 7 
Our goal is to divide 863436 by 7.

Advancing to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 7

Going ahead to step 2:
7 can be fit into 16 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 14 away from 16, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 7

Moving on to step 3:
If we divide 23 by 7, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 21 from 23 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 7

Step 4:
7 goes into 24 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1233.0
Subtract 21 from 24 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 7

Let's proceed to step 5:
The number 7 fits into 33 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 12334.0
Deduct 28 from 33 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

Moving on to step 6:
56 divided by 7 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 123348.0
The remainder is 0 after subtracting 56 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 123348.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 123348.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 123348.0 with a balance of 0.0.
