We look at the division of 231376 by 51 
We want to figure out the number of times 231376 can be divided by 51.

Advancing to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 51

Advancing to step 2:
If we divide 23 by 51, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 51

Going ahead to step 3:
231 divided by 51 is 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 27 after subtracting 204 from 231.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 51

Step 4:
51 can be fit into 273 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 255 from 273, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 51

On to step 5:
187 divided by 51 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 453.0
Deduct 153 from 187 and we're left with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 51

Let's proceed to step 6:
51 can be fit into 346 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4536.0
Subtracting 306 from 346 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 4536.7
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
430 divided by 51 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 4536.78
Subtracting 408 from 430 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.

Let's proceed to step 9:
51 goes into 220 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4536.784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 51, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4536.7843
Subtracting 153 from 160 leaves us 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 11:
If we divide 70 by 51, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 4536.78431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
51 goes into 190 3 times with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 4536.784313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
51 can be fit into 370 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 4536.7843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
130 divided by 51 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 4536.78431372
Deduct 102 from 130 and we're left 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.

The final outcome is 4536.78431372, with a leftover of 2.8e-08.
