97718647 ÷ 306 
The aim is to understand the frequency of 306 in 97718647.

On to step 1:
306 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 306

Let's proceed to step 2:
When dividing 97 by 306, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (7) from the dividend after 97, then repeat: 977 / 306

Going ahead to step 3:
977 divided by 306 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 918 away from 977, we end up with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 306

Going ahead to step 4:
The number 306 fits into 591 1 times, leaving a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 306 away from 591, we end up with 285.
Include the next digit (8) from the dividend after 285, then repeat: 2858 / 306

Going ahead to step 5:
The number 306 fits into 2858 9 times, leaving a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
Subtract 2754 from 2858 to get 104.
Fetch the next digit (6) from the dividend, attach it to 104 and continue: 1046 / 306

Step 6:
306 goes into 1046 3 times with a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 3193.0
Subtract 918 from 1046 to get 128.
Include the next digit (4) from the dividend after 128, then repeat: 1284 / 306

Advancing to step 7:
306 can be fit into 1284 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 31934.0
Subtracting 1224 from 1284 leaves us with 60.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 306

Moving on to step 8:
The number 306 fits into 607 1 times, leaving a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 319341.0
If we subtract 306 from 607, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
3010 divided by 306 is 9 with a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 319341.9
Subtract 2754 from 3010 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 10:
2560 divided by 306 is 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 319341.98
If we take 2448 away from 2560, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
When dividing 1120 by 306, we get 3 with a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 319341.983
Deduct 918 from 1120 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 12:
2020 divided by 306 is 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 319341.9836
The remainder is 184 after subtracting 1836 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
If we divide 1840 by 306, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 319341.98366
Deduct 1836 from 1840 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 319341.98366 and a remainder of 4e-06.
