43909589 ÷ 380 
Let's see how many times 380 fits into 43909589.

Step 1:
380 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 380

Moving on to step 2:
380 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 380

Going ahead to step 3:
439 divided by 380 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 380 from 439, we get 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 380

On to step 4:
When dividing 590 by 380, we get 1 with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 210 after subtracting 380 from 590.
Include the next digit (9) from the dividend after 210, then repeat: 2109 / 380

Let's proceed to step 5:
2109 divided by 380 is 5 with a remainder of 209.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we take 1900 away from 2109, we end up with 209.
Take the next digit (5) from the dividend and append it to 209, then repeat: 2095 / 380

Advancing to step 6:
2095 divided by 380 is 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 1155.0
If we subtract 1900 from 2095, we get 195.
Fetch the next digit (8) from the dividend, attach it to 195 and continue: 1958 / 380

Let's proceed to step 7:
380 can be fit into 1958 5 times, resulting in a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 11555.0
The remainder is 58 after subtracting 1900 from 1958.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 380

Let's proceed to step 8:
The number 380 fits into 589 1 times, leaving a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 115551.0
If we subtract 380 from 589, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
380 goes into 2090 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 115551.5
Deduct 1900 from 2090 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
The number 380 fits into 1900 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 115551.55
If we subtract 1900 from 1900, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 115551.55, and the remainder is 0.0.
