6219069 ÷ 408 
The aim is to understand the frequency of 408 in 6219069.

Moving on to step 1:
408 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 408

Going ahead to step 2:
408 goes into 62 0 times with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 408

Advancing to step 3:
If we divide 621 by 408, we get 1 and a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 408 from 621 leaves us with 213.
Include the next digit (9) from the dividend after 213, then repeat: 2139 / 408

Let's proceed to step 4:
When dividing 2139 by 408, we get 5 with a remainder of 99.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2040 from 2139 leaves us with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 408

Advancing to step 5:
408 goes into 990 2 times with a remainder of 174.
The next digit of our result is 2. 
Result so far: 152.0
Subtracting 816 from 990 leaves us with 174.
Include the next digit (6) from the dividend after 174, then repeat: 1746 / 408

Step 6:
1746 divided by 408 is 4 with a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 1524.0
The remainder is 114 after subtracting 1632 from 1746.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 408

Let's proceed to step 7:
408 goes into 1149 2 times with a remainder of 333.
Put 2 as the next digit of the answer. 
Result so far: 15242.0
The remainder is 333 after subtracting 816 from 1149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 8:
408 goes into 3330 8 times with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 15242.8
If we subtract 3264 from 3330, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
660 divided by 408 is 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 15242.81
If we subtract 408 from 660, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
When dividing 2520 by 408, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 15242.816
Subtracting 2448 from 2520 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
408 goes into 720 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 15242.8161
The remainder is 312 after subtracting 408 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 12:
If we divide 3120 by 408, we get 7 and a remainder of 264.
The number 7 becomes the next digit in our result. 
Result so far: 15242.81617
If we subtract 2856 from 3120, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 13:
2640 divided by 408 is 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 15242.816176
Subtract 2448 from 2640 to 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.

Advancing to step 14:
The number 408 fits into 1920 4 times, leaving a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 15242.8161764
Deduct 1632 from 1920 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
2880 divided by 408 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 15242.81617647
The remainder is 24 after subtracting 2856 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 15242.81617647 and a remainder of 2.4e-08.
