418870 ÷ 8 
Let's see how many times 8 fits into 418870.

On to step 1:
4 divided by 8 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 8

Step 2:
If we divide 41 by 8, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 40 from 41 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 8

Advancing to step 3:
18 divided by 8 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 16 from 18 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 8

Advancing to step 4:
8 can be fit into 28 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 523.0
If we take 24 away from 28, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 8

Going ahead to step 5:
The number 8 fits into 47 5 times, leaving a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5235.0
Subtract 40 from 47 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 8

On to step 6:
If we divide 70 by 8, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 52358.0
If we subtract 64 from 70, 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.

Let's proceed to step 7:
If we divide 60 by 8, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 52358.7
If we take 56 away from 60, we end up 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.

On to step 8:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 52358.75
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.

Advancing to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 52358.75
If we take 0 away from 0, 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 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 52358.75
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 52358.75, with a leftover of 0.0.
