We're dividing 742419 by 51 
The aim is to understand the frequency of 51 in 742419.

Going ahead to step 1:
51 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 51

Going ahead to step 2:
If we divide 74 by 51, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 74, we end up with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 51

Moving on to step 3:
When dividing 232 by 51, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 28 after subtracting 204 from 232.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 51

Advancing to step 4:
51 goes into 284 5 times with a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtract 255 from 284 to get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 51

Let's proceed to step 5:
The number 51 fits into 291 5 times, leaving a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 1455.0
Subtracting 255 from 291 leaves us with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 51

Step 6:
369 divided by 51 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 14557.0
Subtract 357 from 369 to get 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 7:
If we divide 120 by 51, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 14557.2
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 51, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 14557.23
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 14557.235
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.

Going ahead to step 10:
51 goes into 150 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 14557.2352
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.

Going ahead to step 11:
If we divide 480 by 51, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 14557.23529
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
210 divided by 51 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14557.235294
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.

On to step 13:
When dividing 60 by 51, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 14557.2352941
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
If we divide 90 by 51, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 14557.23529411
If we take 51 away from 90, we end up 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.

In conclusion, the division gives 14557.23529411 with a balance of 3.9e-08.
