We're dividing 84188 by 20 
Let's see how many times 20 fits into 84188.

Going ahead to step 1:
20 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.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

On to step 2:
20 goes into 84 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 4 after subtracting 80 from 84.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 20

Let's proceed to step 3:
When dividing 41 by 20, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 42.0
The remainder is 1 after subtracting 40 from 41.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 20

Let's proceed to step 4:
When dividing 18 by 20, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 420.0
Subtract 0 from 18 to get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 20

On to step 5:
20 goes into 188 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4209.0
Deduct 180 from 188 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 6:
If we divide 80 by 20, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4209.4
If we subtract 80 from 80, 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 7:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4209.4
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.

Going ahead to step 8:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4209.4
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.

After the division, we end up with 4209.4 and a remainder of 0.0.
