We divide 13220 by 43
We want to divide 13220 by 43.

Step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 43

Let's proceed to step 2:
The number 43 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 43

Advancing to step 3:
132 divided by 43 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 129 from 132, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 43

Going ahead to step 4:
43 can be fit into 32 0 times, resulting in a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 32 and we're left with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 43

On to step 5:
If we divide 320 by 43, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 307.0
Subtract 301 from 320 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 6:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 307.4
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
If we divide 180 by 43, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 307.44
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 307.44 with a remaining 0.008.
