We're dividing 507869 by 51 
We're looking to find how many times 51 goes into 507869.

Let's proceed to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 51

Going ahead to step 2:
When dividing 50 by 51, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 51

Let's proceed to step 3:
When dividing 507 by 51, we get 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 459 from 507 and we're left with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 51

Moving on to step 4:
51 can be fit into 488 9 times, resulting in a remainder of 29.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 459 from 488 and we're left with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 51

Moving on to step 5:
The number 51 fits into 296 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 995.0
The remainder is 41 after subtracting 255 from 296.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 51

On to step 6:
419 divided by 51 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 9958.0
The remainder is 11 after subtracting 408 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 51, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 9958.2
The remainder is 8 after subtracting 102 from 110.
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 8:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 9958.21
Subtract 51 from 80 to get 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 9:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9958.215
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.

Advancing to step 10:
350 divided by 51 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 9958.2156
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 11:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9958.21568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
320 divided by 51 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9958.215686
The remainder is 14 after subtracting 306 from 320.
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 13:
51 goes into 140 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 9958.2156862
The remainder is 38 after subtracting 102 from 140.
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 14:
If we divide 380 by 51, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 9958.21568627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 9958.21568627, and the remainder is 2.3e-08.
