360644 divided by 51 
The aim is to understand the frequency of 51 in 360644.

Moving on to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 51

Advancing to step 2:
If we divide 36 by 51, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 51

Advancing to step 3:
If we divide 360 by 51, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 357 from 360 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 51

Moving on to step 4:
51 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 51

Advancing to step 5:
When dividing 364 by 51, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 707.0
The remainder is 7 after subtracting 357 from 364.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 51

On to step 6:
51 can be fit into 74 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 7071.0
If we take 51 away from 74, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 51 fits into 230 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7071.4
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7071.45
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
When dividing 50 by 51, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7071.45
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 51, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 7071.4509
Subtract 459 from 500 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
The number 51 fits into 410 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7071.45098
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7071.45098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 7071.4509803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 7071.45098039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 7071.45098039 and a remainder of 1.1e-08.
