177987 divided by 43 
We want to divide 177987 by 43.

Step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 43

Advancing to step 2:
The number 43 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 43

Step 3:
If we divide 177 by 43, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 172 from 177 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 43

Step 4:
If we divide 59 by 43, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 16 after subtracting 43 from 59.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 43

Advancing to step 5:
The number 43 fits into 168 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 413.0
Subtract 129 from 168 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 43

Moving on to step 6:
If we divide 397 by 43, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 4139.0
If we subtract 387 from 397, we get 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 7:
100 divided by 43 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4139.2
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.

Step 8:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 4139.23
Subtracting 129 from 140 leaves us 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.

Step 9:
43 goes into 110 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 4139.232
Deduct 86 from 110 and we're left 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.

Let's proceed to step 10:
When dividing 240 by 43, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4139.2325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4139.23255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 4139.23255 with a remaining 3.5e-05.
