We look at the division of 89428605 by 964 
The aim is to understand the frequency of 964 in 89428605.

Step 1:
964 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 964

Moving on to step 2:
The number 964 fits into 89 0 times, leaving a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 964

Let's proceed to step 3:
When dividing 894 by 964, we get 0 with a remainder of 894.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 894 and we're left with 894.
Include the next digit (2) from the dividend after 894, then repeat: 8942 / 964

Moving on to step 4:
The number 964 fits into 8942 9 times, leaving a remainder of 266.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8676 away from 8942, we end up with 266.
Take the next digit (8) from the dividend and append it to 266, then repeat: 2668 / 964

Advancing to step 5:
If we divide 2668 by 964, we get 2 and a remainder of 740.
The next digit of our result is 2. 
Result so far: 92.0
Subtract 1928 from 2668 to get 740.
Fetch the next digit (6) from the dividend, attach it to 740 and continue: 7406 / 964

Moving on to step 6:
The number 964 fits into 7406 7 times, leaving a remainder of 658.
Use 7 as the next digit of our solution. 
Result so far: 927.0
The remainder is 658 after subtracting 6748 from 7406.
Take the next digit (0) from the dividend and append it to 658, then repeat: 6580 / 964

Let's proceed to step 7:
964 can be fit into 6580 6 times, resulting in a remainder of 796.
The number 6 becomes the next digit in our result. 
Result so far: 9276.0
Subtract 5784 from 6580 to get 796.
Take the next digit (5) from the dividend and append it to 796, then repeat: 7965 / 964

Going ahead to step 8:
964 goes into 7965 8 times with a remainder of 253.
The next digit of our result is 8. 
Result so far: 92768.0
The remainder is 253 after subtracting 7712 from 7965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
964 goes into 2530 2 times with a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 92768.2
Subtracting 1928 from 2530 leaves us with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

On to step 10:
6020 divided by 964 is 6 with a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 92768.26
If we take 5784 away from 6020, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
2360 divided by 964 is 2 with a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 92768.262
Subtract 1928 from 2360 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 12:
964 goes into 4320 4 times with a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 92768.2624
If we take 3856 away from 4320, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 13:
When dividing 4640 by 964, we get 4 with a remainder of 784.
Put 4 as the next digit of the answer. 
Result so far: 92768.26244
The remainder is 784 after subtracting 3856 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Our division results in 92768.26244 with a remaining 0.000784.
