We're dividing 68652636 by 408 
The aim is to understand the frequency of 408 in 68652636.

On to step 1:
408 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 408

Step 2:
68 divided by 408 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 408

Let's proceed to step 3:
If we divide 686 by 408, we get 1 and a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 408 from 686, we get 278.
Append the next digit (5) from the dividend to 278 and continue with: 2785 / 408

Going ahead to step 4:
The number 408 fits into 2785 6 times, leaving a remainder of 337.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2448 away from 2785, we end up with 337.
Fetch the next digit (2) from the dividend, attach it to 337 and continue: 3372 / 408

Going ahead to step 5:
When dividing 3372 by 408, we get 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 168.0
Deduct 3264 from 3372 and we're left with 108.
Append the next digit (6) from the dividend to 108 and continue with: 1086 / 408

Let's proceed to step 6:
408 goes into 1086 2 times with a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 1682.0
If we take 816 away from 1086, we end up with 270.
Fetch the next digit (3) from the dividend, attach it to 270 and continue: 2703 / 408

Let's proceed to step 7:
2703 divided by 408 is 6 with a remainder of 255.
The next digit of our result is 6. 
Result so far: 16826.0
If we subtract 2448 from 2703, we get 255.
Grab the next digit (6) from the dividend, add it to 255, then carry on: 2556 / 408

Advancing to step 8:
The number 408 fits into 2556 6 times, leaving a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 168266.0
Subtract 2448 from 2556 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
408 can be fit into 1080 2 times, resulting in a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 168266.2
Deduct 816 from 1080 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
If we divide 2640 by 408, we get 6 and a remainder of 192.
The next digit of our result is 6. 
Result so far: 168266.26
If we subtract 2448 from 2640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 11:
408 can be fit into 1920 4 times, resulting in a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 168266.264
The remainder is 288 after subtracting 1632 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 12:
When dividing 2880 by 408, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 168266.2647
If we take 2856 away from 2880, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 408, we get 0 and a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 168266.2647
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
When dividing 2400 by 408, we get 5 with a remainder of 360.
The next digit of our result is 5. 
Result so far: 168266.264705
Deduct 2040 from 2400 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
When dividing 3600 by 408, we get 8 with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 168266.2647058
Subtracting 3264 from 3600 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 16:
If we divide 3360 by 408, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 168266.26470588
If we take 3264 away from 3360, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 168266.26470588 and a remainder of 9.6e-08.
