We're dividing 17767293 by 408 
The aim is to understand the frequency of 408 in 17767293.

Let's proceed to step 1:
If we divide 1 by 408, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 408

Going ahead to step 2:
408 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 408

Step 3:
If we divide 177 by 408, we get 0 and a remainder of 177.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 177 to get 177.
Take the next digit (6) from the dividend and append it to 177, then repeat: 1776 / 408

Moving on to step 4:
If we divide 1776 by 408, we get 4 and a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 144 after subtracting 1632 from 1776.
Take the next digit (7) from the dividend and append it to 144, then repeat: 1447 / 408

Step 5:
408 goes into 1447 3 times with a remainder of 223.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 1224 from 1447 leaves us with 223.
Grab the next digit (2) from the dividend, add it to 223, then carry on: 2232 / 408

Let's proceed to step 6:
The number 408 fits into 2232 5 times, leaving a remainder of 192.
The next digit of our result is 5. 
Result so far: 435.0
Subtract 2040 from 2232 to get 192.
Append the next digit (9) from the dividend to 192 and continue with: 1929 / 408

Let's proceed to step 7:
408 can be fit into 1929 4 times, resulting in a remainder of 297.
Put 4 as the next digit of the answer. 
Result so far: 4354.0
If we take 1632 away from 1929, we end up with 297.
Fetch the next digit (3) from the dividend, attach it to 297 and continue: 2973 / 408

Advancing to step 8:
408 can be fit into 2973 7 times, resulting in a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 43547.0
Subtracting 2856 from 2973 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
When dividing 1170 by 408, we get 2 with a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 43547.2
Deduct 816 from 1170 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 10:
If we divide 3540 by 408, we get 8 and a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 43547.28
Deduct 3264 from 3540 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
When dividing 2760 by 408, we get 6 with a remainder of 312.
The next digit of our result is 6. 
Result so far: 43547.286
Subtracting 2448 from 2760 leaves us with 312.
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:
408 can be fit into 3120 7 times, resulting in a remainder of 264.
Put 7 as the next digit of the answer. 
Result so far: 43547.2867
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.

Advancing to step 13:
2640 divided by 408 is 6 with a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 43547.28676
The remainder is 192 after subtracting 2448 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
The number 408 fits into 1920 4 times, leaving a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 43547.286764
If we subtract 1632 from 1920, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
If we divide 2880 by 408, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 43547.2867647
Subtracting 2856 from 2880 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
When dividing 240 by 408, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 43547.2867647
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 43547.2867647 and a remainder of 2.4e-07.
