We look at the division of 31778350 by 408 
The aim is to understand the frequency of 408 in 31778350.

Moving on to step 1:
If we divide 3 by 408, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 408

Moving on to step 2:
31 divided by 408 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 408

Advancing to step 3:
When dividing 317 by 408, we get 0 with a remainder of 317.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 317, we get 317.
Fetch the next digit (7) from the dividend, attach it to 317 and continue: 3177 / 408

Let's proceed to step 4:
The number 408 fits into 3177 7 times, leaving a remainder of 321.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 2856 from 3177, we get 321.
Bring next digit (8) of the dividend behind the 321 and repeat the process: 3218 / 408

Moving on to step 5:
The number 408 fits into 3218 7 times, leaving a remainder of 362.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 2856 from 3218 to get 362.
Append the next digit (3) from the dividend to 362 and continue with: 3623 / 408

Let's proceed to step 6:
The number 408 fits into 3623 8 times, leaving a remainder of 359.
Use 8 as the next digit of our solution. 
Result so far: 778.0
Deduct 3264 from 3623 and we're left with 359.
Append the next digit (5) from the dividend to 359 and continue with: 3595 / 408

Let's proceed to step 7:
When dividing 3595 by 408, we get 8 with a remainder of 331.
Record the quotient 8 as the next digit in the result. 
Result so far: 7788.0
If we take 3264 away from 3595, we end up with 331.
Bring next digit (0) of the dividend behind the 331 and repeat the process: 3310 / 408

Let's proceed to step 8:
408 can be fit into 3310 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 77888.0
Subtracting 3264 from 3310 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
460 divided by 408 is 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 77888.1
Subtract 408 from 460 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
408 can be fit into 520 1 times, resulting in a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 77888.11
If we take 408 away from 520, 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.

Our division results in 77888.11 with a remaining 0.112.
