We look at the division of 177986 by 43 
We're looking to find how many times 43 goes into 177986.

Moving on 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
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 43

Moving on to step 2:
17 divided by 43 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 43

Going ahead to step 3:
177 divided by 43 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 172 away from 177, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 43

Going ahead to step 4:
43 can be fit into 59 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 43 from 59 and we're left with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 43

Advancing to step 5:
When dividing 168 by 43, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 413.0
Subtract 129 from 168 to get 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 43

Advancing to step 6:
When dividing 396 by 43, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 4139.0
The remainder is 9 after subtracting 387 from 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 43 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 4139.2
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 43, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4139.2
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 43, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 4139.209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
If we divide 130 by 43, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 4139.2093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
43 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4139.2093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 43, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4139.209302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
43 goes into 140 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 4139.2093023
If we take 129 away from 140, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
If we divide 110 by 43, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4139.20930232
Subtracting 86 from 110 leaves us 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.

The final outcome is 4139.20930232, with a leftover of 2.4e-08.
