Let's divide 27480701 by 406
The aim is to understand the frequency of 406 in 27480701.

Let's proceed to step 1:
If we divide 2 by 406, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 406

Let's proceed to step 2:
406 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 406

Going ahead to step 3:
The number 406 fits into 274 0 times, leaving a remainder of 274.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 274 after subtracting 0 from 274.
Grab the next digit (8) from the dividend, add it to 274, then carry on: 2748 / 406

Advancing to step 4:
406 can be fit into 2748 6 times, resulting in a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 2436 from 2748 to get 312.
Bring next digit (0) of the dividend behind the 312 and repeat the process: 3120 / 406

Moving on to step 5:
3120 divided by 406 is 7 with a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtract 2842 from 3120 to get 278.
Include the next digit (7) from the dividend after 278, then repeat: 2787 / 406

Moving on to step 6:
2787 divided by 406 is 6 with a remainder of 351.
Use 6 as the next digit of our solution. 
Result so far: 676.0
Subtract 2436 from 2787 to get 351.
Include the next digit (0) from the dividend after 351, then repeat: 3510 / 406

Let's proceed to step 7:
If we divide 3510 by 406, we get 8 and a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 6768.0
The remainder is 262 after subtracting 3248 from 3510.
Grab the next digit (1) from the dividend, add it to 262, then carry on: 2621 / 406

Step 8:
The number 406 fits into 2621 6 times, leaving a remainder of 185.
The next digit of our result is 6. 
Result so far: 67686.0
The remainder is 185 after subtracting 2436 from 2621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 9:
1850 divided by 406 is 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 67686.4
If we subtract 1624 from 1850, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
406 goes into 2260 5 times with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 67686.45
If we take 2030 away from 2260, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
2300 divided by 406 is 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 67686.455
The remainder is 270 after subtracting 2030 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

In conclusion, the division gives 67686.455 with a balance of 0.027.
