We look at the division of 21560199 by 760 
The aim is to understand the frequency of 760 in 21560199.

Going ahead to step 1:
The number 760 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 760

Step 2:
If we divide 21 by 760, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 760

Moving on to step 3:
760 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Append the next digit (6) from the dividend to 215 and continue with: 2156 / 760

Let's proceed to step 4:
2156 divided by 760 is 2 with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1520 from 2156, we get 636.
Append the next digit (0) from the dividend to 636 and continue with: 6360 / 760

Advancing to step 5:
760 can be fit into 6360 8 times, resulting in a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 280 after subtracting 6080 from 6360.
Grab the next digit (1) from the dividend, add it to 280, then carry on: 2801 / 760

Moving on to step 6:
When dividing 2801 by 760, we get 3 with a remainder of 521.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
If we take 2280 away from 2801, we end up with 521.
Take the next digit (9) from the dividend and append it to 521, then repeat: 5219 / 760

Advancing to step 7:
If we divide 5219 by 760, we get 6 and a remainder of 659.
Record the quotient 6 as the next digit in the result. 
Result so far: 2836.0
The remainder is 659 after subtracting 4560 from 5219.
Include the next digit (9) from the dividend after 659, then repeat: 6599 / 760

Step 8:
If we divide 6599 by 760, we get 8 and a remainder of 519.
Put 8 as the next digit of the answer. 
Result so far: 28368.0
Subtract 6080 from 6599 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 9:
The number 760 fits into 5190 6 times, leaving a remainder of 630.
Record the quotient 6 as the next digit in the result. 
Result so far: 28368.6
The remainder is 630 after subtracting 4560 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 10:
The number 760 fits into 6300 8 times, leaving a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 28368.68
Deduct 6080 from 6300 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
760 goes into 2200 2 times with a remainder of 680.
The next digit of our result is 2. 
Result so far: 28368.682
If we subtract 1520 from 2200, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 12:
760 goes into 6800 8 times with a remainder of 720.
The number 8 becomes the next digit in our result. 
Result so far: 28368.6828
Subtracting 6080 from 6800 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 13:
If we divide 7200 by 760, we get 9 and a remainder of 360.
The number 9 becomes the next digit in our result. 
Result so far: 28368.68289
Subtract 6840 from 7200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
3600 divided by 760 is 4 with a remainder of 560.
Put 4 as the next digit of the answer. 
Result so far: 28368.682894
The remainder is 560 after subtracting 3040 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 15:
760 can be fit into 5600 7 times, resulting in a remainder of 280.
Use 7 as the next digit of our solution. 
Result so far: 28368.6828947
The remainder is 280 after subtracting 5320 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
The number 760 fits into 2800 3 times, leaving a remainder of 520.
Use 3 as the next digit of our solution. 
Result so far: 28368.68289473
Deduct 2280 from 2800 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 28368.68289473 with a remainder of 5.2e-07.
