Let's divide 187809 by 43
Let's see how many times 43 fits into 187809.

Step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 43

Advancing to step 2:
18 divided by 43 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 43

Going ahead to step 3:
43 goes into 187 4 times with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 172 from 187 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 43

Advancing to step 4:
43 goes into 158 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 129 from 158 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 43

Going ahead to step 5:
290 divided by 43 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we subtract 258 from 290, we get 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 43

On to step 6:
The number 43 fits into 329 7 times, leaving a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 4367.0
If we subtract 301 from 329, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
280 divided by 43 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 4367.6
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
43 can be fit into 220 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 4367.65
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 43 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4367.651
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
When dividing 70 by 43, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 4367.6511
If we take 43 away from 70, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 4367.6511, with a leftover of 0.00027.
