We're dividing 84215 by 43 
We want to figure out the number of times 84215 can be divided by 43.

On to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 43

Step 2:
When dividing 84 by 43, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 43 from 84 to get 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 43

On to step 3:
43 goes into 412 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 387 from 412 leaves us with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 43

On to step 4:
43 goes into 251 5 times with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we take 215 away from 251, we end up with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 43

Let's proceed to step 5:
If we divide 365 by 43, we get 8 and a remainder of 21.
The next digit of our result is 8. 
Result so far: 1958.0
Subtracting 344 from 365 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 6:
43 goes into 210 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 1958.4
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 43 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1958.48
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 43, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1958.488
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1958.488, with a leftover of 0.0016.
