We're dividing 142504 by 43 
We want to figure out the number of times 142504 can be divided by 43.

Step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 43

Going ahead to step 2:
When dividing 14 by 43, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 43

On to step 3:
43 goes into 142 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 13 after subtracting 129 from 142.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 43

Step 4:
The number 43 fits into 135 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 129 from 135 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 43

On to step 5:
When dividing 60 by 43, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 331.0
If we subtract 43 from 60, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 43

On to step 6:
If we divide 174 by 43, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3314.0
If we take 172 away from 174, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
43 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3314.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 43, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 3314.04
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 43, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 3314.046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
43 goes into 220 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3314.0465
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.

Going ahead to step 11:
43 goes into 50 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 3314.04651
Deduct 43 from 50 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 43, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 3314.046511
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 3314.046511 with a balance of 2.7e-06.
