42919567 divided by 408 
The aim is to understand the frequency of 408 in 42919567.

Going ahead to step 1:
408 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 408

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
Subtract 0 from 42 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 408

Going ahead to step 3:
The number 408 fits into 429 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 408 from 429 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 408

Let's proceed to step 4:
211 divided by 408 is 0 with a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 211 leaves us with 211.
Take the next digit (9) from the dividend and append it to 211, then repeat: 2119 / 408

Advancing to step 5:
When dividing 2119 by 408, we get 5 with a remainder of 79.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 2040 away from 2119, we end up with 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 408

On to step 6:
795 divided by 408 is 1 with a remainder of 387.
Write down 1 as next digit of the result. 
Result so far: 1051.0
If we take 408 away from 795, we end up with 387.
Bring next digit (6) of the dividend behind the 387 and repeat the process: 3876 / 408

Moving on to step 7:
408 can be fit into 3876 9 times, resulting in a remainder of 204.
Write down 9 as next digit of the result. 
Result so far: 10519.0
If we subtract 3672 from 3876, we get 204.
Grab the next digit (7) from the dividend, add it to 204, then carry on: 2047 / 408

Going ahead to step 8:
When dividing 2047 by 408, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 105195.0
The remainder is 7 after subtracting 2040 from 2047.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
408 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 105195.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
408 can be fit into 700 1 times, resulting in a remainder of 292.
The number 1 becomes the next digit in our result. 
Result so far: 105195.01
Deduct 408 from 700 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 11:
408 can be fit into 2920 7 times, resulting in a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 105195.017
Subtract 2856 from 2920 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
408 goes into 640 1 times with a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 105195.0171
The remainder is 232 after subtracting 408 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
When dividing 2320 by 408, we get 5 with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 105195.01715
If we take 2040 away from 2320, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
If we divide 2800 by 408, we get 6 and a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 105195.017156
Subtract 2448 from 2800 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 15:
When dividing 3520 by 408, we get 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 105195.0171568
Deduct 3264 from 3520 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
408 can be fit into 2560 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 105195.01715686
Deduct 2448 from 2560 and we're left 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.

The final outcome is 105195.01715686, with a leftover of 1.12e-07.
