Let's divide 77808392 by 988
The aim is to understand the frequency of 988 in 77808392.

On to step 1:
If we divide 7 by 988, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 988

Moving on to step 2:
988 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 988

Advancing to step 3:
The number 988 fits into 778 0 times, leaving a remainder of 778.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 778 after subtracting 0 from 778.
Bring next digit (0) of the dividend behind the 778 and repeat the process: 7780 / 988

On to step 4:
988 can be fit into 7780 7 times, resulting in a remainder of 864.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 6916 from 7780, we get 864.
Append the next digit (8) from the dividend to 864 and continue with: 8648 / 988

Going ahead to step 5:
When dividing 8648 by 988, we get 8 with a remainder of 744.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 7904 from 8648 leaves us with 744.
Include the next digit (3) from the dividend after 744, then repeat: 7443 / 988

Going ahead to step 6:
7443 divided by 988 is 7 with a remainder of 527.
The number 7 becomes the next digit in our result. 
Result so far: 787.0
The remainder is 527 after subtracting 6916 from 7443.
Fetch the next digit (9) from the dividend, attach it to 527 and continue: 5279 / 988

Going ahead to step 7:
When dividing 5279 by 988, we get 5 with a remainder of 339.
Record the quotient 5 as the next digit in the result. 
Result so far: 7875.0
If we subtract 4940 from 5279, we get 339.
Fetch the next digit (2) from the dividend, attach it to 339 and continue: 3392 / 988

Step 8:
988 goes into 3392 3 times with a remainder of 428.
Record the quotient 3 as the next digit in the result. 
Result so far: 78753.0
If we take 2964 away from 3392, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 9:
When dividing 4280 by 988, we get 4 with a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 78753.4
Deduct 3952 from 4280 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
988 can be fit into 3280 3 times, resulting in a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 78753.43
The remainder is 316 after subtracting 2964 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
988 goes into 3160 3 times with a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 78753.433
Subtract 2964 from 3160 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

In conclusion, the division gives 78753.433 with a balance of 0.0196.
