Let's divide 19699124 by 408
The aim is to understand the frequency of 408 in 19699124.

Going ahead to step 1:
1 divided by 408 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 408

Let's proceed to step 2:
If we divide 19 by 408, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 408

Advancing to step 3:
408 can be fit into 196 0 times, resulting in a remainder of 196.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Bring next digit (9) of the dividend behind the 196 and repeat the process: 1969 / 408

On to step 4:
408 goes into 1969 4 times with a remainder of 337.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1632 away from 1969, we end up with 337.
Append the next digit (9) from the dividend to 337 and continue with: 3379 / 408

Step 5:
When dividing 3379 by 408, we get 8 with a remainder of 115.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
The remainder is 115 after subtracting 3264 from 3379.
Fetch the next digit (1) from the dividend, attach it to 115 and continue: 1151 / 408

Moving on to step 6:
When dividing 1151 by 408, we get 2 with a remainder of 335.
Use 2 as the next digit of our solution. 
Result so far: 482.0
If we take 816 away from 1151, we end up with 335.
Bring next digit (2) of the dividend behind the 335 and repeat the process: 3352 / 408

On to step 7:
When dividing 3352 by 408, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 4828.0
Subtract 3264 from 3352 to get 88.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 408

Moving on to step 8:
When dividing 884 by 408, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 48282.0
The remainder is 68 after subtracting 816 from 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
408 can be fit into 680 1 times, resulting in a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 48282.1
If we subtract 408 from 680, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
408 can be fit into 2720 6 times, resulting in a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 48282.16
Subtracting 2448 from 2720 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 11:
2720 divided by 408 is 6 with a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 48282.166
The remainder is 272 after subtracting 2448 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Our division results in 48282.166 with a remaining 0.0272.
