We divide 81363322 by 721
The aim is to understand the frequency of 721 in 81363322.

Let's proceed to step 1:
8 divided by 721 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 721

Step 2:
The number 721 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 721

On to step 3:
If we divide 813 by 721, we get 1 and a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 92 after subtracting 721 from 813.
Include the next digit (6) from the dividend after 92, then repeat: 926 / 721

Step 4:
The number 721 fits into 926 1 times, leaving a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 721 from 926 leaves us with 205.
Bring next digit (3) of the dividend behind the 205 and repeat the process: 2053 / 721

Moving on to step 5:
If we divide 2053 by 721, we get 2 and a remainder of 611.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
The remainder is 611 after subtracting 1442 from 2053.
Fetch the next digit (3) from the dividend, attach it to 611 and continue: 6113 / 721

Advancing to step 6:
If we divide 6113 by 721, we get 8 and a remainder of 345.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
If we subtract 5768 from 6113, we get 345.
Fetch the next digit (2) from the dividend, attach it to 345 and continue: 3452 / 721

Going ahead to step 7:
The number 721 fits into 3452 4 times, leaving a remainder of 568.
Record the quotient 4 as the next digit in the result. 
Result so far: 11284.0
If we subtract 2884 from 3452, we get 568.
Bring next digit (2) of the dividend behind the 568 and repeat the process: 5682 / 721

Moving on to step 8:
The number 721 fits into 5682 7 times, leaving a remainder of 635.
Record the quotient 7 as the next digit in the result. 
Result so far: 112847.0
If we take 5047 away from 5682, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 9:
If we divide 6350 by 721, we get 8 and a remainder of 582.
Record the quotient 8 as the next digit in the result. 
Result so far: 112847.8
Subtract 5768 from 6350 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 10:
721 can be fit into 5820 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 112847.88
The remainder is 52 after subtracting 5768 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 112847.88, and the remainder is 0.052.
