131720 divided by 43 
Let's see how many times 43 fits into 131720.

Step 1:
43 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 43

On to step 2:
13 divided by 43 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 43

Moving on to step 3:
43 can be fit into 131 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 2 after subtracting 129 from 131.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 43

Step 4:
27 divided by 43 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 43

Let's proceed to step 5:
43 goes into 272 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 306.0
The remainder is 14 after subtracting 258 from 272.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 43

Let's proceed to step 6:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3063.0
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 43, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3063.2
Deduct 86 from 110 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3063.25
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 43 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3063.255
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 3063.255 and a remainder of 0.0035.
