Let's divide 454259 by 51
Let's see how many times 51 fits into 454259.

Going ahead to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 51

Let's proceed to step 2:
51 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 51

Step 3:
454 divided by 51 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 408 from 454 leaves us with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 51

Going ahead to step 4:
The number 51 fits into 462 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 459 from 462, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 51

Step 5:
51 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 890.0
Subtract 0 from 35 to get 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 51

Going ahead to step 6:
51 can be fit into 359 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 8907.0
If we subtract 357 from 359, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8907.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 51 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 8907.03
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
When dividing 470 by 51, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8907.039
Deduct 459 from 470 and we're left with 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 10:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8907.0392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 51, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8907.03921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
51 goes into 290 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8907.039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
If we divide 350 by 51, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8907.0392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8907.03921568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 8907.03921568 with a remainder of 3.2e-08.
