We're dividing 28889667 by 406 
The aim is to understand the frequency of 406 in 28889667.

Let's proceed to step 1:
406 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 406

Advancing to step 2:
406 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 406

Moving on to step 3:
406 can be fit into 288 0 times, resulting in a remainder of 288.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 288 to get 288.
Fetch the next digit (8) from the dividend, attach it to 288 and continue: 2888 / 406

Moving on to step 4:
406 goes into 2888 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 2842 from 2888 and we're left with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 406

Moving on to step 5:
469 divided by 406 is 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 406 from 469 leaves us with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 406

On to step 6:
406 can be fit into 636 1 times, resulting in a remainder of 230.
Write down 1 as next digit of the result. 
Result so far: 711.0
If we subtract 406 from 636, we get 230.
Grab the next digit (6) from the dividend, add it to 230, then carry on: 2306 / 406

Advancing to step 7:
When dividing 2306 by 406, we get 5 with a remainder of 276.
Use 5 as the next digit of our solution. 
Result so far: 7115.0
If we subtract 2030 from 2306, we get 276.
Append the next digit (7) from the dividend to 276 and continue with: 2767 / 406

On to step 8:
The number 406 fits into 2767 6 times, leaving a remainder of 331.
Put 6 as the next digit of the answer. 
Result so far: 71156.0
Subtracting 2436 from 2767 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 9:
When dividing 3310 by 406, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 71156.8
Subtracting 3248 from 3310 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
When dividing 620 by 406, we get 1 with a remainder of 214.
Use 1 as the next digit of our solution. 
Result so far: 71156.81
If we subtract 406 from 620, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 11:
The number 406 fits into 2140 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 71156.815
If we take 2030 away from 2140, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
If we divide 1100 by 406, we get 2 and a remainder of 288.
Record the quotient 2 as the next digit in the result. 
Result so far: 71156.8152
Subtracting 812 from 1100 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 13:
When dividing 2880 by 406, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 71156.81527
The remainder is 38 after subtracting 2842 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
When dividing 380 by 406, we get 0 with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 71156.81527
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
If we divide 3800 by 406, we get 9 and a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 71156.8152709
Deduct 3654 from 3800 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 16:
If we divide 1460 by 406, we get 3 and a remainder of 242.
The next digit of our result is 3. 
Result so far: 71156.81527093
Deduct 1218 from 1460 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 71156.81527093 with a balance of 2.42e-07.
