We look at the division of 858530 by 51 
Let's see how many times 51 fits into 858530.

Step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 51

Step 2:
The number 51 fits into 85 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 85 leaves us with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 51

Let's proceed to step 3:
51 can be fit into 348 6 times, resulting in a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 306 away from 348, we end up with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 51

Going ahead to step 4:
The number 51 fits into 425 8 times, leaving a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Subtracting 408 from 425 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 51

Moving on to step 5:
173 divided by 51 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 1683.0
The remainder is 20 after subtracting 153 from 173.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 51

Advancing to step 6:
200 divided by 51 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 16833.0
Deduct 153 from 200 and we're left 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.

Step 7:
When dividing 470 by 51, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 16833.9
If we take 459 away from 470, we end up 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.

On to step 8:
110 divided by 51 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16833.92
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 16833.921
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 10:
If we divide 290 by 51, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 16833.9215
If we take 255 away from 290, we end up 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.

Let's proceed to step 11:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 16833.92156
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.

Going ahead to step 12:
51 goes into 440 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 16833.921568
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 13:
When dividing 320 by 51, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 16833.9215686
Deduct 306 from 320 and we're left 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.

On to step 14:
51 goes into 140 2 times with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 16833.92156862
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.

The quotient of the division is 16833.92156862, and the remainder is 3.8e-08.
