642886 ÷ 8 
We want to divide 642886 by 8.

Let's proceed to step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 8

Step 2:
64 divided by 8 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 64 from 64, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 8

Advancing to step 3:
When dividing 2 by 8, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 8

On to step 4:
If we divide 28 by 8, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 803.0
If we take 24 away from 28, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 8

Advancing to step 5:
If we divide 48 by 8, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 8036.0
If we take 48 away from 48, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 8

Going ahead to step 6:
8 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 80360.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 80360.7
Subtracting 56 from 60 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.

Going ahead to step 8:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 80360.75
If we take 40 away from 40, 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 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80360.75
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.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80360.75
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.

The final outcome is 80360.75, with a leftover of 0.0.
