Let's divide 550429 by 8
We're looking to find how many times 8 goes into 550429.

Going ahead to step 1:
8 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 8

On to step 2:
The number 8 fits into 55 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 48 from 55 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 8

Step 3:
If we divide 70 by 8, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 68.0
If we take 64 away from 70, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 8

Moving on to step 4:
When dividing 64 by 8, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 688.0
The remainder is 0 after subtracting 64 from 64.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 8

On to step 5:
8 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 6880.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 8

Going ahead to step 6:
8 can be fit into 29 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 68803.0
Subtract 24 from 29 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.

Moving on to step 7:
When dividing 50 by 8, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 68803.6
The remainder is 2 after subtracting 48 from 50.
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 8:
If we divide 20 by 8, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 68803.62
If we subtract 16 from 20, 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.

Going ahead to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 68803.625
Subtract 40 from 40 to 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.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 68803.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 68803.625
Subtract 0 from 0 to 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.

The final outcome is 68803.625, with a leftover of 0.0.
