Let's divide 63696240 by 308
The aim is to understand the frequency of 308 in 63696240.

Going ahead to step 1:
6 divided by 308 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 308

Step 2:
308 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 308

Moving on to step 3:
If we divide 636 by 308, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 616 from 636, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 308

On to step 4:
The number 308 fits into 209 0 times, leaving a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 209 to get 209.
Bring next digit (6) of the dividend behind the 209 and repeat the process: 2096 / 308

Let's proceed to step 5:
If we divide 2096 by 308, we get 6 and a remainder of 248.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
If we take 1848 away from 2096, we end up with 248.
Include the next digit (2) from the dividend after 248, then repeat: 2482 / 308

Going ahead to step 6:
When dividing 2482 by 308, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2068.0
Deduct 2464 from 2482 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 308

Going ahead to step 7:
308 can be fit into 184 0 times, resulting in a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 20680.0
If we take 0 away from 184, we end up with 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 308

Step 8:
308 goes into 1840 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 206805.0
If we take 1540 away from 1840, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 9:
The number 308 fits into 3000 9 times, leaving a remainder of 228.
Record the quotient 9 as the next digit in the result. 
Result so far: 206805.9
Deduct 2772 from 3000 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
2280 divided by 308 is 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 206805.97
Subtract 2156 from 2280 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
When dividing 1240 by 308, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 206805.974
Deduct 1232 from 1240 and we're left with 8.
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 12:
80 divided by 308 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 206805.974
If we take 0 away from 80, we end up 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.

Step 13:
The number 308 fits into 800 2 times, leaving a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 206805.97402
If we subtract 616 from 800, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 14:
308 goes into 1840 5 times with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 206805.974025
Subtracting 1540 from 1840 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 15:
The number 308 fits into 3000 9 times, leaving a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 206805.9740259
If we subtract 2772 from 3000, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 16:
2280 divided by 308 is 7 with a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 206805.97402597
Deduct 2156 from 2280 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 206805.97402597, with a leftover of 1.24e-07.
