We're dividing 53077009 by 8 
We want to divide 53077009 by 8.

Moving on to step 1:
8 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 8

Advancing to step 2:
8 goes into 53 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 48 away from 53, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Advancing to step 3:
8 goes into 50 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 48 from 50 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 8

Let's proceed to step 4:
27 divided by 8 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 663.0
Subtract 24 from 27 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 8

Going ahead to step 5:
8 can be fit into 37 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 6634.0
Subtracting 32 from 37 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 8

Moving on to step 6:
When dividing 50 by 8, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 66346.0
If we subtract 48 from 50, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 8

Moving on to step 7:
When dividing 20 by 8, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 663462.0
If we subtract 16 from 20, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 8

Advancing to step 8:
8 can be fit into 49 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 6634626.0
Subtract 48 from 49 to 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.

On to step 9:
If we divide 10 by 8, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 6634626.1
The remainder is 2 after subtracting 8 from 10.
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 10:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 6634626.12
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 6634626.125
The remainder is 0 after subtracting 40 from 40.
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 12:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6634626.125
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.

Step 13:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6634626.125
Subtracting 0 from 0 leaves us 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.

The final outcome is 6634626.125, with a leftover of 0.0.
