858028 divided by 51 
The aim is to understand the frequency of 51 in 858028.

Step 1:
8 divided by 51 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 51

Moving on to step 2:
If we divide 85 by 51, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 85, we end up with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 51

Let's proceed to step 3:
51 can be fit into 348 6 times, resulting in a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 306 from 348 and we're left with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 51

Moving on to step 4:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 408 from 420 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 51

Let's proceed to step 5:
When dividing 122 by 51, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1682.0
The remainder is 20 after subtracting 102 from 122.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 51

Step 6:
If we divide 208 by 51, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 16824.0
Subtract 204 from 208 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 51 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 16824.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 51, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 16824.07
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 51 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 16824.078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
51 goes into 220 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 16824.0784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 16824.07843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
If we divide 70 by 51, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 16824.078431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 16824.0784313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 16824.07843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 16824.07843137 and a remainder of 1.3e-08.
