33630473 divided by 721 
The aim is to understand the frequency of 721 in 33630473.

Going ahead to step 1:
721 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 721

Let's proceed to step 2:
721 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 721

Moving on to step 3:
336 divided by 721 is 0 with a remainder of 336.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 336 to get 336.
Fetch the next digit (3) from the dividend, attach it to 336 and continue: 3363 / 721

Advancing to step 4:
When dividing 3363 by 721, we get 4 with a remainder of 479.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 2884 from 3363 leaves us with 479.
Fetch the next digit (0) from the dividend, attach it to 479 and continue: 4790 / 721

Let's proceed to step 5:
If we divide 4790 by 721, we get 6 and a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Deduct 4326 from 4790 and we're left with 464.
Append the next digit (4) from the dividend to 464 and continue with: 4644 / 721

Step 6:
When dividing 4644 by 721, we get 6 with a remainder of 318.
Write down 6 as next digit of the result. 
Result so far: 466.0
Subtract 4326 from 4644 to get 318.
Append the next digit (7) from the dividend to 318 and continue with: 3187 / 721

Moving on to step 7:
3187 divided by 721 is 4 with a remainder of 303.
Record the quotient 4 as the next digit in the result. 
Result so far: 4664.0
The remainder is 303 after subtracting 2884 from 3187.
Bring next digit (3) of the dividend behind the 303 and repeat the process: 3033 / 721

Advancing to step 8:
721 goes into 3033 4 times with a remainder of 149.
Record the quotient 4 as the next digit in the result. 
Result so far: 46644.0
The remainder is 149 after subtracting 2884 from 3033.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
1490 divided by 721 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 46644.2
The remainder is 48 after subtracting 1442 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 721 is 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 46644.2
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
721 can be fit into 4800 6 times, resulting in a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 46644.206
Deduct 4326 from 4800 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 12:
When dividing 4740 by 721, we get 6 with a remainder of 414.
The number 6 becomes the next digit in our result. 
Result so far: 46644.2066
If we subtract 4326 from 4740, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final outcome is 46644.2066, with a leftover of 0.00414.
