587039 ÷ 51 
Let's see how many times 51 fits into 587039.

On to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 51

Going ahead to step 2:
58 divided by 51 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 58, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 51

Step 3:
The number 51 fits into 77 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 51 from 77, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 51

Step 4:
When dividing 260 by 51, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtracting 255 from 260 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 51

Let's proceed to step 5:
The number 51 fits into 53 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1151.0
Subtracting 51 from 53 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 51

Let's proceed to step 6:
If we divide 29 by 51, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 11510.0
If we take 0 away from 29, we end up 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 7:
If we divide 290 by 51, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 11510.5
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
350 divided by 51 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 11510.56
Subtract 306 from 350 to 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.

Moving on to step 9:
When dividing 440 by 51, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 11510.568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 51, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 11510.5686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 51 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 11510.56862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
When dividing 380 by 51, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 11510.568627
Subtracting 357 from 380 leaves us 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.

Advancing to step 13:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 11510.5686274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
260 divided by 51 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11510.56862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 11510.56862745, with a leftover of 5e-09.
