We divide 538806 by 51
The aim is to understand the frequency of 51 in 538806.

Step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 51

Going ahead to step 2:
53 divided by 51 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 51 from 53.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 51

Going ahead to step 3:
28 divided by 51 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 51

Moving on to step 4:
51 goes into 288 5 times with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 255 from 288 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 51

Advancing to step 5:
When dividing 330 by 51, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1056.0
If we subtract 306 from 330, we get 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 51

Moving on to step 6:
If we divide 246 by 51, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 10564.0
If we subtract 204 from 246, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 10564.8
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 10564.82
Subtract 102 from 120 to get 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 9:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 10564.823
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
51 goes into 270 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10564.8235
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.

Going ahead to step 11:
51 can be fit into 150 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10564.82352
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.

Let's proceed to step 12:
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: 10564.823529
If we take 459 away from 480, we end up 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.

Going ahead to step 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 10564.8235294
Subtracting 204 from 210 leaves us 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.

Let's proceed to step 14:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 10564.82352941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 10564.82352941 and a remainder of 9e-09.
