We look at the division of 89664298 by 977 
The aim is to understand the frequency of 977 in 89664298.

Step 1:
8 divided by 977 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 977

Going ahead to step 2:
When dividing 89 by 977, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Bring next digit (6) of the dividend behind the 89 and repeat the process: 896 / 977

Advancing to step 3:
977 goes into 896 0 times with a remainder of 896.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 896, we end up with 896.
Take the next digit (6) from the dividend and append it to 896, then repeat: 8966 / 977

Going ahead to step 4:
977 can be fit into 8966 9 times, resulting in a remainder of 173.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 8793 from 8966 leaves us with 173.
Include the next digit (4) from the dividend after 173, then repeat: 1734 / 977

Step 5:
1734 divided by 977 is 1 with a remainder of 757.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 977 from 1734 leaves us with 757.
Include the next digit (2) from the dividend after 757, then repeat: 7572 / 977

Moving on to step 6:
977 goes into 7572 7 times with a remainder of 733.
The number 7 becomes the next digit in our result. 
Result so far: 917.0
Subtracting 6839 from 7572 leaves us with 733.
Grab the next digit (9) from the dividend, add it to 733, then carry on: 7339 / 977

Moving on to step 7:
7339 divided by 977 is 7 with a remainder of 500.
Put 7 as the next digit of the answer. 
Result so far: 9177.0
Subtracting 6839 from 7339 leaves us with 500.
Take the next digit (8) from the dividend and append it to 500, then repeat: 5008 / 977

Let's proceed to step 8:
The number 977 fits into 5008 5 times, leaving a remainder of 123.
Use 5 as the next digit of our solution. 
Result so far: 91775.0
The remainder is 123 after subtracting 4885 from 5008.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
1230 divided by 977 is 1 with a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 91775.1
The remainder is 253 after subtracting 977 from 1230.
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 10:
2530 divided by 977 is 2 with a remainder of 576.
The number 2 becomes the next digit in our result. 
Result so far: 91775.12
Subtract 1954 from 2530 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 11:
When dividing 5760 by 977, we get 5 with a remainder of 875.
Write down 5 as next digit of the result. 
Result so far: 91775.125
Deduct 4885 from 5760 and we're left with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Step 12:
The number 977 fits into 8750 8 times, leaving a remainder of 934.
The number 8 becomes the next digit in our result. 
Result so far: 91775.1258
Deduct 7816 from 8750 and we're left with 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Let's proceed to step 13:
When dividing 9340 by 977, we get 9 with a remainder of 547.
Put 9 as the next digit of the answer. 
Result so far: 91775.12589
If we take 8793 away from 9340, we end up with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Let's proceed to step 14:
When dividing 5470 by 977, we get 5 with a remainder of 585.
Write down 5 as next digit of the result. 
Result so far: 91775.125895
The remainder is 585 after subtracting 4885 from 5470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 15:
5850 divided by 977 is 5 with a remainder of 965.
Record the quotient 5 as the next digit in the result. 
Result so far: 91775.1258955
Subtract 4885 from 5850 to get 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

After the division, we end up with 91775.1258955 and a remainder of 9.65e-06.
