440448 ÷ 51 
The aim is to understand the frequency of 51 in 440448.

Let's proceed to step 1:
4 divided by 51 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 51

Step 2:
44 divided by 51 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 51

On to step 3:
51 goes into 440 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 408 from 440, we get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 51

Going ahead to step 4:
The number 51 fits into 324 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 306 away from 324, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 51

Going ahead to step 5:
184 divided by 51 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
If we take 153 away from 184, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 51

Advancing to step 6:
51 goes into 318 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 8636.0
The remainder is 12 after subtracting 306 from 318.
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 7:
51 can be fit into 120 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 8636.2
Subtracting 102 from 120 leaves us 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.

On to step 8:
The number 51 fits into 180 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 8636.23
Subtracting 153 from 180 leaves us 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.

Moving on to step 9:
51 goes into 270 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8636.235
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 51, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8636.2352
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.

Advancing to step 11:
The number 51 fits into 480 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 8636.23529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
If we divide 210 by 51, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 8636.235294
If we subtract 204 from 210, we get 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 13:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 8636.2352941
Subtract 51 from 60 to 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.

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: 8636.23529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 8636.23529411 with a remaining 3.9e-08.
