We look at the division of 20727998 by 964 
The aim is to understand the frequency of 964 in 20727998.

Going ahead to step 1:
If we divide 2 by 964, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 964

Step 2:
The number 964 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 964

Let's proceed to step 3:
207 divided by 964 is 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Grab the next digit (2) from the dividend, add it to 207, then carry on: 2072 / 964

Step 4:
The number 964 fits into 2072 2 times, leaving a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 144 after subtracting 1928 from 2072.
Grab the next digit (7) from the dividend, add it to 144, then carry on: 1447 / 964

Let's proceed to step 5:
When dividing 1447 by 964, we get 1 with a remainder of 483.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 964 from 1447, we get 483.
Append the next digit (9) from the dividend to 483 and continue with: 4839 / 964

Advancing to step 6:
The number 964 fits into 4839 5 times, leaving a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
The remainder is 19 after subtracting 4820 from 4839.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 964

On to step 7:
If we divide 199 by 964, we get 0 and a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 2150.0
Subtracting 0 from 199 leaves us with 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 964

Going ahead to step 8:
The number 964 fits into 1998 2 times, leaving a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 21502.0
The remainder is 70 after subtracting 1928 from 1998.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
When dividing 700 by 964, we get 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 21502.0
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 10:
964 can be fit into 7000 7 times, resulting in a remainder of 252.
Write down 7 as next digit of the result. 
Result so far: 21502.07
Subtracting 6748 from 7000 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
964 goes into 2520 2 times with a remainder of 592.
Put 2 as the next digit of the answer. 
Result so far: 21502.072
Deduct 1928 from 2520 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 12:
If we divide 5920 by 964, we get 6 and a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 21502.0726
Subtract 5784 from 5920 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
The number 964 fits into 1360 1 times, leaving a remainder of 396.
The number 1 becomes the next digit in our result. 
Result so far: 21502.07261
If we take 964 away from 1360, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 14:
964 goes into 3960 4 times with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 21502.072614
The remainder is 104 after subtracting 3856 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
964 goes into 1040 1 times with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 21502.0726141
Deduct 964 from 1040 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
When dividing 760 by 964, we get 0 with a remainder of 760.
Use 0 as the next digit of our solution. 
Result so far: 21502.0726141
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

After the division, we end up with 21502.0726141 and a remainder of 7.6e-07.
