We're dividing 186912 by 43 
Our goal is to divide 186912 by 43.

Going ahead to 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
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 43

On to step 2:
18 divided by 43 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 43

Step 3:
When dividing 186 by 43, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 172 from 186 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 43

Moving on to step 4:
43 goes into 149 3 times with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 20 after subtracting 129 from 149.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 43

Step 5:
43 can be fit into 201 4 times, resulting in a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
The remainder is 29 after subtracting 172 from 201.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 43

On to step 6:
The number 43 fits into 292 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 4346.0
If we subtract 258 from 292, we get 34.
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 7:
43 can be fit into 340 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 4346.7
If we subtract 301 from 340, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 43, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 4346.79
If we take 387 away from 390, we end up 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.

Moving on to step 9:
The number 43 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4346.79
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 43, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 4346.7906
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.

Going ahead to step 11:
420 divided by 43 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 4346.79069
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.

Let's proceed to step 12:
330 divided by 43 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 4346.790697
Deduct 301 from 330 and we're left with 29.
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 13:
The number 43 fits into 290 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 4346.7906976
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 43, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 4346.79069767
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.

The final result is 4346.79069767 with a remainder of 1.9e-08.
