We look at the division of 447486 by 51 
The aim is to understand the frequency of 51 in 447486.

Moving on to step 1:
51 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 51

Moving on to step 2:
When dividing 44 by 51, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 51

Going ahead to step 3:
51 can be fit into 447 8 times, resulting in a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 39 after subtracting 408 from 447.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 51

Going ahead to step 4:
51 goes into 394 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 357 from 394 leaves us with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 51

Step 5:
51 goes into 378 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 877.0
Deduct 357 from 378 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 51

On to step 6:
If we divide 216 by 51, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8774.0
If we subtract 204 from 216, we 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.

Going ahead to step 7:
If we divide 120 by 51, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 8774.2
If we subtract 102 from 120, we 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.

Going ahead to step 8:
When dividing 180 by 51, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 8774.23
Subtract 153 from 180 to get 27.
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.
Use 5 as the next digit of our solution. 
Result so far: 8774.235
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.

On to step 10:
51 goes into 150 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 8774.2352
If we subtract 102 from 150, we get 48.
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:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 8774.23529
Deduct 459 from 480 and we're left 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.

Step 12:
51 goes into 210 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 8774.235294
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.

Moving on to step 13:
When dividing 60 by 51, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 8774.2352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
51 goes into 90 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 8774.23529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 8774.23529411 with a balance of 3.9e-08.
