We're dividing 15622758 by 720 
The aim is to understand the frequency of 720 in 15622758.

Advancing to step 1:
When dividing 1 by 720, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 720

Going ahead to step 2:
If we divide 15 by 720, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 720

Step 3:
If we divide 156 by 720, we get 0 and a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Take the next digit (2) from the dividend and append it to 156, then repeat: 1562 / 720

Advancing to step 4:
1562 divided by 720 is 2 with a remainder of 122.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1440 from 1562 leaves us with 122.
Fetch the next digit (2) from the dividend, attach it to 122 and continue: 1222 / 720

Going ahead to step 5:
When dividing 1222 by 720, we get 1 with a remainder of 502.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 720 away from 1222, we end up with 502.
Bring next digit (7) of the dividend behind the 502 and repeat the process: 5027 / 720

Step 6:
720 can be fit into 5027 6 times, resulting in a remainder of 707.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 4320 from 5027, we get 707.
Include the next digit (5) from the dividend after 707, then repeat: 7075 / 720

Advancing to step 7:
720 can be fit into 7075 9 times, resulting in a remainder of 595.
The next digit of our result is 9. 
Result so far: 2169.0
Subtracting 6480 from 7075 leaves us with 595.
Take the next digit (8) from the dividend and append it to 595, then repeat: 5958 / 720

Moving on to step 8:
720 can be fit into 5958 8 times, resulting in a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 21698.0
The remainder is 198 after subtracting 5760 from 5958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 9:
The number 720 fits into 1980 2 times, leaving a remainder of 540.
Record the quotient 2 as the next digit in the result. 
Result so far: 21698.2
The remainder is 540 after subtracting 1440 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 10:
720 can be fit into 5400 7 times, resulting in a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 21698.27
Deduct 5040 from 5400 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
720 goes into 3600 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21698.275
Subtract 3600 from 3600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
720 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21698.275
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
720 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 21698.275
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 21698.275 with a remainder of 0.0.
