857730 divided by 51 
The aim is to understand the frequency of 51 in 857730.

Let's proceed to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 51

On to step 2:
The number 51 fits into 85 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 85, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 51

Step 3:
51 goes into 347 6 times with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 41 after subtracting 306 from 347.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 51

Step 4:
If we divide 417 by 51, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we take 408 away from 417, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 51

Advancing to step 5:
The number 51 fits into 93 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1681.0
If we take 51 away from 93, we end up with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 51

Let's proceed to step 6:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 16818.0
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 51 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 16818.2
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 51 fits into 180 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 16818.23
The remainder is 27 after subtracting 153 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
51 can be fit into 270 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 16818.235
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 51 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 16818.2352
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 51, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 16818.23529
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 16818.235294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 16818.2352941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
If we divide 90 by 51, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 16818.23529411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 16818.23529411, and the remainder is 3.9e-08.
