373542 divided by 51 
The aim is to understand the frequency of 51 in 373542.

Moving on to step 1:
51 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 51

Let's proceed to step 2:
37 divided by 51 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 51

Advancing to step 3:
51 can be fit into 373 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 16 after subtracting 357 from 373.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 51

Let's proceed to step 4:
When dividing 165 by 51, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 153 from 165, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 51

Moving on to step 5:
When dividing 124 by 51, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 732.0
If we take 102 away from 124, we end up with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 51

Moving on to step 6:
51 goes into 222 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 7324.0
If we take 204 away from 222, we end up 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 7:
180 divided by 51 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 7324.3
The remainder is 27 after subtracting 153 from 180.
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 8:
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: 7324.35
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 9:
51 can be fit into 150 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7324.352
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.

Step 10:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 7324.3529
If we subtract 459 from 480, we get 21.
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 11:
210 divided by 51 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7324.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
51 goes into 60 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 7324.352941
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.

Let's proceed to step 13:
When dividing 90 by 51, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 7324.3529411
Subtract 51 from 90 to get 39.
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 7324.3529411 with a balance of 3.9e-07.
