We're dividing 125187 by 43 
We're looking to find how many times 43 goes into 125187.

Advancing to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 43

Moving on to step 2:
When dividing 12 by 43, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 43

On to step 3:
If we divide 125 by 43, we get 2 and a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 86 from 125 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 43

Going ahead to step 4:
If we divide 391 by 43, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 4 after subtracting 387 from 391.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 43

On to step 5:
The number 43 fits into 48 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 291.0
Subtracting 43 from 48 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 43

Step 6:
43 can be fit into 57 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 2911.0
Subtracting 43 from 57 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 7:
If we divide 140 by 43, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 2911.3
Subtract 129 from 140 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
43 can be fit into 110 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2911.32
If we take 86 away from 110, we end up 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.

Step 9:
When dividing 240 by 43, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2911.325
Deduct 215 from 240 and we're left 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 10:
250 divided by 43 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2911.3255
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 2911.3255 with a balance of 0.00035.
