We divide 642510 by 8
Let's see how many times 8 fits into 642510.

Going ahead to step 1:
8 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 8

On to step 2:
When dividing 64 by 8, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 64 away from 64, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 8

On to step 3:
8 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 8

On to step 4:
When dividing 25 by 8, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 803.0
If we take 24 away from 25, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Let's proceed to step 5:
When dividing 11 by 8, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8031.0
The remainder is 3 after subtracting 8 from 11.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 8

Let's proceed to step 6:
30 divided by 8 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 80313.0
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 80313.7
The remainder is 4 after subtracting 56 from 60.
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 8:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 80313.75
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.

Let's proceed to step 9:
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: 80313.75
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.

Advancing to step 10:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80313.75
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.

The final result is 80313.75 with a remainder of 0.0.
