502742 ÷ 51 
We want to figure out the number of times 502742 can be divided by 51.

Advancing to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 51

Going ahead to step 2:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 51

Going ahead to step 3:
51 can be fit into 502 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 459 from 502 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 51

Let's proceed to step 4:
51 goes into 437 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 408 from 437, we get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 51

Advancing to step 5:
294 divided by 51 is 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 985.0
If we subtract 255 from 294, we get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 51

Let's proceed to step 6:
If we divide 392 by 51, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 9857.0
The remainder is 35 after subtracting 357 from 392.
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 7:
51 goes into 350 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9857.6
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.

Step 8:
When dividing 440 by 51, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9857.68
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.

Let's proceed to step 9:
When dividing 320 by 51, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9857.686
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 10:
When dividing 140 by 51, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 9857.6862
If we take 102 away from 140, we end up 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.

Advancing to step 11:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 9857.68627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
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: 9857.686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
51 can be fit into 260 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9857.6862745
Deduct 255 from 260 and we're left 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.

Advancing to step 14:
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: 9857.6862745
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 9857.6862745 and a remainder of 5e-08.
