We divide 620573 by 8
We want to figure out the number of times 620573 can be divided by 8.

Advancing to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 8

On to step 2:
The number 8 fits into 62 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 56 from 62 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 8

Step 3:
If we divide 60 by 8, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 4 after subtracting 56 from 60.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 8

On to step 4:
45 divided by 8 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 775.0
If we take 40 away from 45, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 8

On to step 5:
If we divide 57 by 8, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7757.0
If we take 56 away from 57, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 8

On to step 6:
The number 8 fits into 13 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 77571.0
If we take 8 away from 13, we end up with 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 7:
The number 8 fits into 50 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 77571.6
If we take 48 away from 50, we end up 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.

Advancing to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 77571.62
Subtracting 16 from 20 leaves us 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.

Step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 77571.625
If we subtract 40 from 40, 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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 77571.625
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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77571.625
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.

After the division, we end up with 77571.625 and a remainder of 0.0.
