We look at the division of 7164663 by 406 
The aim is to understand the frequency of 406 in 7164663.

Moving on to step 1:
7 divided by 406 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 406

Moving on to step 2:
406 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 406

Going ahead to step 3:
406 can be fit into 716 1 times, resulting in a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 406 from 716 to get 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 406

On to step 4:
When dividing 3104 by 406, we get 7 with a remainder of 262.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 262 after subtracting 2842 from 3104.
Fetch the next digit (6) from the dividend, attach it to 262 and continue: 2626 / 406

On to step 5:
2626 divided by 406 is 6 with a remainder of 190.
Write down 6 as next digit of the result. 
Result so far: 176.0
Deduct 2436 from 2626 and we're left with 190.
Take the next digit (6) from the dividend and append it to 190, then repeat: 1906 / 406

Step 6:
1906 divided by 406 is 4 with a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 1764.0
Subtract 1624 from 1906 to get 282.
Fetch the next digit (3) from the dividend, attach it to 282 and continue: 2823 / 406

Advancing to step 7:
When dividing 2823 by 406, we get 6 with a remainder of 387.
The next digit of our result is 6. 
Result so far: 17646.0
If we take 2436 away from 2823, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 8:
If we divide 3870 by 406, we get 9 and a remainder of 216.
The next digit of our result is 9. 
Result so far: 17646.9
If we take 3654 away from 3870, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
If we divide 2160 by 406, we get 5 and a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 17646.95
The remainder is 130 after subtracting 2030 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
406 can be fit into 1300 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 17646.953
Subtract 1218 from 1300 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
406 goes into 820 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 17646.9532
Deduct 812 from 820 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
406 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 17646.9532
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
406 goes into 800 1 times with a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 17646.953201
If we take 406 away from 800, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 14:
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: 17646.9532019
Deduct 3654 from 3940 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 15:
The number 406 fits into 2860 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 17646.95320197
If we subtract 2842 from 2860, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 17646.95320197 with a balance of 1.8e-08.
