We're dividing 98773615 by 345 
The aim is to understand the frequency of 345 in 98773615.

Going ahead to step 1:
345 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 345

Going ahead to step 2:
When dividing 98 by 345, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 345

Step 3:
The number 345 fits into 987 2 times, leaving a remainder of 297.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 690 from 987 to get 297.
Include the next digit (7) from the dividend after 297, then repeat: 2977 / 345

On to step 4:
When dividing 2977 by 345, we get 8 with a remainder of 217.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 2760 from 2977 to get 217.
Take the next digit (3) from the dividend and append it to 217, then repeat: 2173 / 345

Step 5:
2173 divided by 345 is 6 with a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
If we take 2070 away from 2173, we end up with 103.
Grab the next digit (6) from the dividend, add it to 103, then carry on: 1036 / 345

Step 6:
345 can be fit into 1036 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 2863.0
If we subtract 1035 from 1036, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 345

Step 7:
The number 345 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 28630.0
If we take 0 away from 11, we end up with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 345

Moving on to step 8:
345 goes into 115 0 times with a remainder of 115.
Use 0 as the next digit of our solution. 
Result so far: 286300.0
Subtract 0 from 115 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
If we divide 1150 by 345, we get 3 and a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 286300.3
If we subtract 1035 from 1150, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
The number 345 fits into 1150 3 times, leaving a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 286300.33
The remainder is 115 after subtracting 1035 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final result is 286300.33 with a remainder of 0.115.
