We're dividing 732402 by 51 
The aim is to understand the frequency of 51 in 732402.

Step 1:
51 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 51

On to step 2:
If we divide 73 by 51, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 73, we get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 51

Moving on to step 3:
When dividing 222 by 51, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 204 from 222, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 51

Moving on to step 4:
51 goes into 184 3 times with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtracting 153 from 184 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 51

Going ahead to step 5:
51 goes into 310 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1436.0
If we subtract 306 from 310, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 51

On to step 6:
The number 51 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 14360.0
If we subtract 0 from 42, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
420 divided by 51 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 14360.8
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
The number 51 fits into 120 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 14360.82
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 51 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 14360.823
Deduct 153 from 180 and we're left 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.

On to step 10:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 14360.8235
Deduct 255 from 270 and we're left 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.

On to step 11:
51 goes into 150 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 14360.82352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
51 goes into 480 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 14360.823529
Subtract 459 from 480 to 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.

On to step 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14360.8235294
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.

On to step 14:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 14360.82352941
If we subtract 51 from 60, we 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.

The quotient of the division is 14360.82352941, and the remainder is 9e-09.
