We're dividing 739520 by 51 
The aim is to understand the frequency of 51 in 739520.

On to step 1:
7 divided by 51 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 51

Moving on to step 2:
51 can be fit into 73 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 73 and we're left with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 51

Going ahead to step 3:
51 can be fit into 229 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 204 from 229 leaves us with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 51

Let's proceed to step 4:
When dividing 255 by 51, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Deduct 255 from 255 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 51

Advancing to step 5:
If we divide 2 by 51, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1450.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 51

Step 6:
20 divided by 51 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14500.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 14500.3
Subtract 153 from 200 to 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.

Step 8:
51 goes into 470 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 14500.39
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 51, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 14500.392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 14500.3921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 14500.39215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
350 divided by 51 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14500.392156
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
The number 51 fits into 440 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 14500.3921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
If we divide 320 by 51, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 14500.39215686
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 14500.39215686 with a remaining 1.4e-08.
