We're dividing 551558 by 7 
Let's see how many times 7 fits into 551558.

Step 1:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 7

On to step 2:
7 goes into 55 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 49 from 55 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 7

Step 3:
61 divided by 7 is 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 56 from 61 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Going ahead to step 4:
When dividing 55 by 7, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 787.0
The remainder is 6 after subtracting 49 from 55.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 7

On to step 5:
7 can be fit into 65 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 7879.0
Subtracting 63 from 65 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 7

Let's proceed to step 6:
28 divided by 7 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 78794.0
Deduct 28 from 28 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.

Moving on to step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 78794.0
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.

Step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 78794.0
If we subtract 0 from 0, we get 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 78794.0 with a balance of 0.0.
