We're dividing 203570 by 8 
We want to figure out the number of times 203570 can be divided by 8.

Going ahead to step 1:
8 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 8

Step 2:
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: 2.0
Deduct 16 from 20 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 8

Moving on to step 3:
43 divided by 8 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 40 from 43, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 8

Moving on to step 4:
35 divided by 8 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 32 from 35 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 8

On to step 5:
37 divided by 8 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 2544.0
Subtracting 32 from 37 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Let's proceed to step 6:
If we divide 50 by 8, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 25446.0
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 25446.2
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.

Advancing 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: 25446.25
Deduct 40 from 40 and we're left 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 9:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25446.25
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 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25446.25
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.

The quotient of the division is 25446.25, and the remainder is 0.0.
