We divide 459139 by 51
We want to figure out the number of times 459139 can be divided by 51.

Moving on to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 51

On to step 2:
51 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 51

Let's proceed to step 3:
459 divided by 51 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 459 from 459 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 51

Moving on to step 4:
51 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 51

Advancing to step 5:
51 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 900.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 51

Step 6:
51 can be fit into 139 2 times, resulting in a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 9002.0
If we subtract 102 from 139, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
51 can be fit into 370 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 9002.7
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
If we divide 130 by 51, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9002.72
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
51 can be fit into 280 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9002.725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
51 goes into 250 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 9002.7254
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9002.72549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9002.72549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 9002.7254901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
51 can be fit into 490 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 9002.72549019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 9002.72549019, with a leftover of 3.1e-08.
