151236 ÷ 43 
We want to divide 151236 by 43.

Advancing to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 43

Step 2:
43 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 43

Advancing to step 3:
151 divided by 43 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 129 from 151 and we're left with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 43

Going ahead to step 4:
When dividing 222 by 43, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 215 from 222 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 43

Going ahead to step 5:
The number 43 fits into 73 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 351.0
If we subtract 43 from 73, we get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 43

On to step 6:
43 goes into 306 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 3517.0
The remainder is 5 after subtracting 301 from 306.
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 7:
When dividing 50 by 43, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 3517.1
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.

Let's proceed to step 8:
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: 3517.11
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 3517.11, with a leftover of 0.027.
