Let's divide 51051676 by 721
The aim is to understand the frequency of 721 in 51051676.

Let's proceed to step 1:
5 divided by 721 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 721

Let's proceed to step 2:
51 divided by 721 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 721

Going ahead to step 3:
If we divide 510 by 721, we get 0 and a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 510 leaves us with 510.
Grab the next digit (5) from the dividend, add it to 510, then carry on: 5105 / 721

Let's proceed to step 4:
721 goes into 5105 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5047 from 5105, we get 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 721

Let's proceed to step 5:
581 divided by 721 is 0 with a remainder of 581.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we take 0 away from 581, we end up with 581.
Bring next digit (6) of the dividend behind the 581 and repeat the process: 5816 / 721

Going ahead to step 6:
When dividing 5816 by 721, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 708.0
The remainder is 48 after subtracting 5768 from 5816.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 721

Advancing to step 7:
721 goes into 487 0 times with a remainder of 487.
Use 0 as the next digit of our solution. 
Result so far: 7080.0
Deduct 0 from 487 and we're left with 487.
Fetch the next digit (6) from the dividend, attach it to 487 and continue: 4876 / 721

Step 8:
If we divide 4876 by 721, we get 6 and a remainder of 550.
The next digit of our result is 6. 
Result so far: 70806.0
Deduct 4326 from 4876 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 9:
The number 721 fits into 5500 7 times, leaving a remainder of 453.
Write down 7 as next digit of the result. 
Result so far: 70806.7
Subtract 5047 from 5500 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 10:
When dividing 4530 by 721, we get 6 with a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 70806.76
Subtracting 4326 from 4530 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
When dividing 2040 by 721, we get 2 with a remainder of 598.
The number 2 becomes the next digit in our result. 
Result so far: 70806.762
The remainder is 598 after subtracting 1442 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 12:
721 can be fit into 5980 8 times, resulting in a remainder of 212.
The next digit of our result is 8. 
Result so far: 70806.7628
If we subtract 5768 from 5980, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 13:
When dividing 2120 by 721, we get 2 with a remainder of 678.
Record the quotient 2 as the next digit in the result. 
Result so far: 70806.76282
Deduct 1442 from 2120 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Advancing to step 14:
When dividing 6780 by 721, we get 9 with a remainder of 291.
Put 9 as the next digit of the answer. 
Result so far: 70806.762829
The remainder is 291 after subtracting 6489 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 15:
When dividing 2910 by 721, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 70806.7628294
Subtract 2884 from 2910 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 16:
If we divide 260 by 721, we get 0 and a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 70806.7628294
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 70806.7628294, with a leftover of 2.6e-07.
