We're dividing 221577 by 43 
We want to divide 221577 by 43.

Let's proceed to step 1:
When dividing 2 by 43, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 43

Moving on to step 2:
43 can be fit into 22 0 times, resulting in 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.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 43

Going ahead to step 3:
The number 43 fits into 221 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 215 from 221 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 43

Step 4:
If we divide 65 by 43, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 43 from 65, we get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 43

Step 5:
The number 43 fits into 227 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 515.0
Subtracting 215 from 227 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 43

Moving on to step 6:
When dividing 127 by 43, we get 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 5152.0
The remainder is 41 after subtracting 86 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
When dividing 410 by 43, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 5152.9
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
When dividing 230 by 43, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5152.95
If we take 215 away from 230, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 43 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 5152.953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
210 divided by 43 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 5152.9534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
When dividing 380 by 43, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5152.95348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5152.953488
Subtract 344 from 360 to get 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 5152.953488, with a leftover of 1.6e-06.
