We're dividing 152187 by 43 
We want to divide 152187 by 43.

Step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 43

Going ahead to step 2:
When dividing 15 by 43, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 43

Step 3:
152 divided by 43 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 129 from 152 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 43

Let's proceed to step 4:
231 divided by 43 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 215 from 231 to get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 43

Going ahead to step 5:
43 goes into 168 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 353.0
Deduct 129 from 168 and we're left with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 43

On to step 6:
The number 43 fits into 397 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3539.0
The remainder is 10 after subtracting 387 from 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 43 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 3539.2
Subtracting 86 from 100 leaves us 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.

Advancing to step 8:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3539.23
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 9:
110 divided by 43 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3539.232
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.

Moving on to step 10:
If we divide 240 by 43, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 3539.2325
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
43 goes into 250 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3539.23255
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 3539.23255 and a remainder of 3.5e-05.
