We look at the division of 231438 by 51 
Our goal is to divide 231438 by 51.

Going ahead to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 51

On to step 2:
If we divide 23 by 51, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 51

Step 3:
The number 51 fits into 231 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 204 from 231 and we're left with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 51

Step 4:
274 divided by 51 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 45.0
If we take 255 away from 274, we end up with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 51

Advancing to step 5:
When dividing 193 by 51, we get 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 453.0
If we take 153 away from 193, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 51

Let's proceed to step 6:
When dividing 408 by 51, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4538.0
Subtract 408 from 408 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 51 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4538.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 51, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4538.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4538.0, with a leftover of 0.0.
