We're dividing 12432134 by 301 
We want to divide 12432134 by 301.

Moving on to step 1:
301 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 301

Let's proceed to step 2:
The number 301 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 301

Let's proceed to step 3:
301 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Bring next digit (3) of the dividend behind the 124 and repeat the process: 1243 / 301

Step 4:
1243 divided by 301 is 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 1204 from 1243, we get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 301

Let's proceed to step 5:
When dividing 392 by 301, we get 1 with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 301 away from 392, we end up with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 301

Let's proceed to step 6:
The number 301 fits into 911 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 413.0
If we subtract 903 from 911, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 301

On to step 7:
When dividing 83 by 301, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 4130.0
If we subtract 0 from 83, we get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 301

Let's proceed to step 8:
If we divide 834 by 301, we get 2 and a remainder of 232.
The next digit of our result is 2. 
Result so far: 41302.0
The remainder is 232 after subtracting 602 from 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
2320 divided by 301 is 7 with a remainder of 213.
The next digit of our result is 7. 
Result so far: 41302.7
If we take 2107 away from 2320, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 10:
The number 301 fits into 2130 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 41302.77
Deduct 2107 from 2130 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 41302.77, with a leftover of 0.023.
