Let's divide 18659035 by 435
We're looking to find how many times 435 goes into 18659035.

Moving on to step 1:
435 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 435

On to step 2:
435 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 435

Advancing to step 3:
435 goes into 186 0 times with a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 186 to get 186.
Fetch the next digit (5) from the dividend, attach it to 186 and continue: 1865 / 435

Going ahead to step 4:
When dividing 1865 by 435, we get 4 with a remainder of 125.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1740 away from 1865, we end up with 125.
Append the next digit (9) from the dividend to 125 and continue with: 1259 / 435

On to step 5:
If we divide 1259 by 435, we get 2 and a remainder of 389.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 870 away from 1259, we end up with 389.
Fetch the next digit (0) from the dividend, attach it to 389 and continue: 3890 / 435

Advancing to step 6:
435 goes into 3890 8 times with a remainder of 410.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
If we subtract 3480 from 3890, we get 410.
Append the next digit (3) from the dividend to 410 and continue with: 4103 / 435

Going ahead to step 7:
435 goes into 4103 9 times with a remainder of 188.
Record the quotient 9 as the next digit in the result. 
Result so far: 4289.0
Subtract 3915 from 4103 to get 188.
Fetch the next digit (5) from the dividend, attach it to 188 and continue: 1885 / 435

Step 8:
If we divide 1885 by 435, we get 4 and a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 42894.0
If we take 1740 away from 1885, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
When dividing 1450 by 435, we get 3 with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 42894.3
Deduct 1305 from 1450 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
If we divide 1450 by 435, we get 3 and a remainder of 145.
The next digit of our result is 3. 
Result so far: 42894.33
Subtract 1305 from 1450 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 42894.33 with a remaining 0.145.
