We look at the division of 97492884 by 977 
The aim is to understand the frequency of 977 in 97492884.

On to step 1:
When dividing 9 by 977, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 977

Going ahead to step 2:
97 divided by 977 is 0 with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (4) from the dividend after 97, then repeat: 974 / 977

Let's proceed to step 3:
When dividing 974 by 977, we get 0 with a remainder of 974.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 974, we get 974.
Grab the next digit (9) from the dividend, add it to 974, then carry on: 9749 / 977

Going ahead to step 4:
977 goes into 9749 9 times with a remainder of 956.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 956 after subtracting 8793 from 9749.
Bring next digit (2) of the dividend behind the 956 and repeat the process: 9562 / 977

Step 5:
When dividing 9562 by 977, we get 9 with a remainder of 769.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 8793 from 9562, we get 769.
Append the next digit (8) from the dividend to 769 and continue with: 7698 / 977

Going ahead to step 6:
977 can be fit into 7698 7 times, resulting in a remainder of 859.
The number 7 becomes the next digit in our result. 
Result so far: 997.0
If we take 6839 away from 7698, we end up with 859.
Append the next digit (8) from the dividend to 859 and continue with: 8598 / 977

Let's proceed to step 7:
If we divide 8598 by 977, we get 8 and a remainder of 782.
The next digit of our result is 8. 
Result so far: 9978.0
Subtracting 7816 from 8598 leaves us with 782.
Grab the next digit (4) from the dividend, add it to 782, then carry on: 7824 / 977

Let's proceed to step 8:
If we divide 7824 by 977, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 99788.0
The remainder is 8 after subtracting 7816 from 7824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 977, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 99788.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
977 can be fit into 800 0 times, resulting in a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 99788.0
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 99788.0, with a leftover of 0.8.
