We look at the division of 17556058 by 406 
The aim is to understand the frequency of 406 in 17556058.

Let's proceed to step 1:
406 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 406

Going ahead to step 2:
The number 406 fits into 17 0 times, leaving 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.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 406

Moving on to step 3:
The number 406 fits into 175 0 times, leaving a remainder of 175.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 175, we get 175.
Include the next digit (5) from the dividend after 175, then repeat: 1755 / 406

Going ahead to step 4:
If we divide 1755 by 406, we get 4 and a remainder of 131.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1624 from 1755 to get 131.
Fetch the next digit (6) from the dividend, attach it to 131 and continue: 1316 / 406

Let's proceed to step 5:
406 can be fit into 1316 3 times, resulting in a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 1218 from 1316 leaves us with 98.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 406

Advancing to step 6:
The number 406 fits into 980 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 432.0
Subtracting 812 from 980 leaves us with 168.
Take the next digit (5) from the dividend and append it to 168, then repeat: 1685 / 406

Moving on to step 7:
The number 406 fits into 1685 4 times, leaving a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 4324.0
The remainder is 61 after subtracting 1624 from 1685.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 406

Going ahead to step 8:
406 goes into 618 1 times with a remainder of 212.
The next digit of our result is 1. 
Result so far: 43241.0
The remainder is 212 after subtracting 406 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 9:
If we divide 2120 by 406, we get 5 and a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 43241.5
Subtract 2030 from 2120 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
When dividing 900 by 406, we get 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 43241.52
The remainder is 88 after subtracting 812 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
If we divide 880 by 406, we get 2 and a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 43241.522
The remainder is 68 after subtracting 812 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 43241.522 and a remainder of 0.0068.
