We're dividing 187449 by 43 
We want to divide 187449 by 43.

Moving on to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 43

Advancing to step 2:
18 divided by 43 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 43

Step 3:
187 divided by 43 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 172 away from 187, we end up with 15.

On to step 5:
254 divided by 43 is 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we subtract 215 from 254, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 43

On to step 6:
When dividing 399 by 43, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 4359.0
Subtract 387 from 399 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 43 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 4359.2
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 43 fits into 340 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 4359.27
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
43 can be fit into 390 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 4359.279
Deduct 387 from 390 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 43 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4359.279
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4359.27906
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
When dividing 420 by 43, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 4359.279069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 4359.2790697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
43 goes into 290 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 4359.27906976
The remainder is 32 after subtracting 258 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 4359.27906976 with a remaining 3.2e-08.
