We look at the division of 21991865 by 760 
The aim is to understand the frequency of 760 in 21991865.

Let's proceed to step 1:
The number 760 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 760

Moving on to step 2:
If we divide 21 by 760, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 760

Advancing to step 3:
When dividing 219 by 760, we get 0 with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Grab the next digit (9) from the dividend, add it to 219, then carry on: 2199 / 760

Let's proceed to step 4:
When dividing 2199 by 760, we get 2 with a remainder of 679.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 679 after subtracting 1520 from 2199.
Append the next digit (1) from the dividend to 679 and continue with: 6791 / 760

Let's proceed to step 5:
6791 divided by 760 is 8 with a remainder of 711.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 711 after subtracting 6080 from 6791.
Include the next digit (8) from the dividend after 711, then repeat: 7118 / 760

Going ahead to step 6:
760 can be fit into 7118 9 times, resulting in a remainder of 278.
The next digit of our result is 9. 
Result so far: 289.0
If we take 6840 away from 7118, we end up with 278.
Grab the next digit (6) from the dividend, add it to 278, then carry on: 2786 / 760

Advancing to step 7:
2786 divided by 760 is 3 with a remainder of 506.
The next digit of our result is 3. 
Result so far: 2893.0
Subtracting 2280 from 2786 leaves us with 506.
Bring next digit (5) of the dividend behind the 506 and repeat the process: 5065 / 760

Let's proceed to step 8:
760 goes into 5065 6 times with a remainder of 505.
Use 6 as the next digit of our solution. 
Result so far: 28936.0
The remainder is 505 after subtracting 4560 from 5065.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
The number 760 fits into 5050 6 times, leaving a remainder of 490.
Put 6 as the next digit of the answer. 
Result so far: 28936.6
If we take 4560 away from 5050, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 10:
4900 divided by 760 is 6 with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 28936.66
Subtracting 4560 from 4900 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 28936.66, with a leftover of 0.34.
