We look at the division of 93572432 by 406 
The aim is to understand the frequency of 406 in 93572432.

Step 1:
If we divide 9 by 406, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 406

Going ahead to step 2:
When dividing 93 by 406, we get 0 with a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Take the next digit (5) from the dividend and append it to 93, then repeat: 935 / 406

Advancing to step 3:
406 can be fit into 935 2 times, resulting in a remainder of 123.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 812 from 935, we get 123.
Append the next digit (7) from the dividend to 123 and continue with: 1237 / 406

Let's proceed to step 4:
If we divide 1237 by 406, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 1218 from 1237 to get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 406

Going ahead to step 5:
When dividing 192 by 406, we get 0 with a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Deduct 0 from 192 and we're left with 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 406

Step 6:
If we divide 1924 by 406, we get 4 and a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 2304.0
Deduct 1624 from 1924 and we're left with 300.
Take the next digit (3) from the dividend and append it to 300, then repeat: 3003 / 406

On to step 7:
406 can be fit into 3003 7 times, resulting in a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 23047.0
If we take 2842 away from 3003, we end up with 161.
Include the next digit (2) from the dividend after 161, then repeat: 1612 / 406

Advancing to step 8:
When dividing 1612 by 406, we get 3 with a remainder of 394.
The next digit of our result is 3. 
Result so far: 230473.0
If we subtract 1218 from 1612, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 9:
406 can be fit into 3940 9 times, resulting in a remainder of 286.
The next digit of our result is 9. 
Result so far: 230473.9
Subtract 3654 from 3940 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
If we divide 2860 by 406, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 230473.97
Subtracting 2842 from 2860 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 406 fits into 180 0 times, leaving a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 230473.97
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 406 is 4 with a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 230473.9704
Deduct 1624 from 1800 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
406 goes into 1760 4 times with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 230473.97044
The remainder is 136 after subtracting 1624 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 230473.97044 with a remaining 0.000136.
