We're dividing 51794660 by 721 
The aim is to understand the frequency of 721 in 51794660.

Moving on to step 1:
721 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 721

Step 2:
721 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 721

Moving on to step 3:
The number 721 fits into 517 0 times, leaving a remainder of 517.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 517 and we're left with 517.
Grab the next digit (9) from the dividend, add it to 517, then carry on: 5179 / 721

Let's proceed to step 4:
The number 721 fits into 5179 7 times, leaving a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 132 after subtracting 5047 from 5179.
Fetch the next digit (4) from the dividend, attach it to 132 and continue: 1324 / 721

Moving on to step 5:
1324 divided by 721 is 1 with a remainder of 603.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 721 from 1324 and we're left with 603.
Include the next digit (6) from the dividend after 603, then repeat: 6036 / 721

On to step 6:
The number 721 fits into 6036 8 times, leaving a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 718.0
If we take 5768 away from 6036, we end up with 268.
Include the next digit (6) from the dividend after 268, then repeat: 2686 / 721

Moving on to step 7:
721 can be fit into 2686 3 times, resulting in a remainder of 523.
Put 3 as the next digit of the answer. 
Result so far: 7183.0
Subtract 2163 from 2686 to get 523.
Take the next digit (0) from the dividend and append it to 523, then repeat: 5230 / 721

Moving on to step 8:
The number 721 fits into 5230 7 times, leaving a remainder of 183.
The next digit of our result is 7. 
Result so far: 71837.0
Deduct 5047 from 5230 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 9:
If we divide 1830 by 721, we get 2 and a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 71837.2
If we take 1442 away from 1830, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 10:
The number 721 fits into 3880 5 times, leaving a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 71837.25
Subtract 3605 from 3880 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
If we divide 2750 by 721, we get 3 and a remainder of 587.
The next digit of our result is 3. 
Result so far: 71837.253
The remainder is 587 after subtracting 2163 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 12:
When dividing 5870 by 721, we get 8 with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 71837.2538
If we take 5768 away from 5870, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 13:
When dividing 1020 by 721, we get 1 with a remainder of 299.
The next digit of our result is 1. 
Result so far: 71837.25381
Subtracting 721 from 1020 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 14:
When dividing 2990 by 721, we get 4 with a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 71837.253814
Deduct 2884 from 2990 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 15:
When dividing 1060 by 721, we get 1 with a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 71837.2538141
The remainder is 339 after subtracting 721 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 16:
If we divide 3390 by 721, we get 4 and a remainder of 506.
Record the quotient 4 as the next digit in the result. 
Result so far: 71837.25381414
Subtract 2884 from 3390 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

In conclusion, the division gives 71837.25381414 with a balance of 5.06e-07.
