We divide 83430 by 20
We're looking to find how many times 20 goes into 83430.

Let's proceed to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Step 2:
When dividing 83 by 20, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 80 from 83 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 20

Moving on to step 3:
34 divided by 20 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 20 from 34 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 20

Let's proceed to step 4:
If we divide 143 by 20, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 417.0
If we take 140 away from 143, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Moving on to step 5:
When dividing 30 by 20, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 4171.0
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 6:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4171.5
If we take 100 away from 100, 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.

Let's proceed to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4171.5
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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4171.5
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.

Our division results in 4171.5 with a remaining 0.0.
