We look at the division of 221392 by 43 
We want to figure out the number of times 221392 can be divided by 43.

Advancing to step 1:
43 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 43

Moving on to step 2:
If we divide 22 by 43, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 43

Advancing to step 3:
221 divided by 43 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 6 after subtracting 215 from 221.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 43

Let's proceed to step 4:
When dividing 63 by 43, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 43 from 63 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 43

Moving on to step 5:
When dividing 209 by 43, we get 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 514.0
If we subtract 172 from 209, we get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 43

Advancing to step 6:
372 divided by 43 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 5148.0
Subtracting 344 from 372 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
43 can be fit into 280 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 5148.6
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
220 divided by 43 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5148.65
If we subtract 215 from 220, 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.

Going ahead to step 9:
43 goes into 50 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 5148.651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 5148.6511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 5148.6511 with a remaining 0.00027.
