We look at the division of 870435 by 22 
We want to figure out the number of times 870435 can be divided by 22.

Going ahead to step 1:
22 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 22

Let's proceed to step 2:
When dividing 87 by 22, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 66 from 87 leaves us with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 22

Step 3:
210 divided by 22 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 12 after subtracting 198 from 210.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 22

Let's proceed to step 4:
22 goes into 124 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 395.0
The remainder is 14 after subtracting 110 from 124.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 22

Step 5:
143 divided by 22 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 3956.0
If we subtract 132 from 143, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 22

Let's proceed to step 6:
22 goes into 115 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39565.0
If we subtract 110 from 115, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 22, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 39565.2
The remainder is 6 after subtracting 44 from 50.
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 8:
If we divide 60 by 22, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 39565.22
If we subtract 44 from 60, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 39565.22 and a remainder of 0.016.
