We're dividing 42794465 by 408 
The aim is to understand the frequency of 408 in 42794465.

Let's proceed to step 1:
4 divided by 408 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 408

Moving on to step 2:
If we divide 42 by 408, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 408

Going ahead to step 3:
408 goes into 427 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 408 from 427 to get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 408

Advancing to step 4:
When dividing 199 by 408, we get 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 199 after subtracting 0 from 199.
Bring next digit (4) of the dividend behind the 199 and repeat the process: 1994 / 408

Advancing to step 5:
408 can be fit into 1994 4 times, resulting in a remainder of 362.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 1632 from 1994, we get 362.
Grab the next digit (4) from the dividend, add it to 362, then carry on: 3624 / 408

Going ahead to step 6:
The number 408 fits into 3624 8 times, leaving a remainder of 360.
The next digit of our result is 8. 
Result so far: 1048.0
If we subtract 3264 from 3624, we get 360.
Grab the next digit (6) from the dividend, add it to 360, then carry on: 3606 / 408

Moving on to step 7:
3606 divided by 408 is 8 with a remainder of 342.
Use 8 as the next digit of our solution. 
Result so far: 10488.0
If we subtract 3264 from 3606, we get 342.
Include the next digit (5) from the dividend after 342, then repeat: 3425 / 408

Going ahead to step 8:
408 can be fit into 3425 8 times, resulting in a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 104888.0
Subtracting 3264 from 3425 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 9:
1610 divided by 408 is 3 with a remainder of 386.
The next digit of our result is 3. 
Result so far: 104888.3
If we subtract 1224 from 1610, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 10:
The number 408 fits into 3860 9 times, leaving a remainder of 188.
Use 9 as the next digit of our solution. 
Result so far: 104888.39
If we subtract 3672 from 3860, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
The number 408 fits into 1880 4 times, leaving a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 104888.394
If we take 1632 away from 1880, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
408 can be fit into 2480 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 104888.3946
Deduct 2448 from 2480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
If we divide 320 by 408, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 104888.3946
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
The number 408 fits into 3200 7 times, leaving a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 104888.394607
Deduct 2856 from 3200 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
If we divide 3440 by 408, we get 8 and a remainder of 176.
The next digit of our result is 8. 
Result so far: 104888.3946078
Subtract 3264 from 3440 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
1760 divided by 408 is 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 104888.39460784
Subtracting 1632 from 1760 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 104888.39460784 with a remainder of 1.28e-07.
