88289116 divided by 409 
The aim is to understand the frequency of 409 in 88289116.

Step 1:
409 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 409

Advancing to step 2:
409 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 409

Step 3:
If we divide 882 by 409, we get 2 and a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 818 from 882, we get 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 409

Moving on to step 4:
When dividing 648 by 409, we get 1 with a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 239 after subtracting 409 from 648.
Append the next digit (9) from the dividend to 239 and continue with: 2399 / 409

Moving on to step 5:
2399 divided by 409 is 5 with a remainder of 354.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we subtract 2045 from 2399, we get 354.
Append the next digit (1) from the dividend to 354 and continue with: 3541 / 409

Moving on to step 6:
The number 409 fits into 3541 8 times, leaving a remainder of 269.
The number 8 becomes the next digit in our result. 
Result so far: 2158.0
Deduct 3272 from 3541 and we're left with 269.
Bring next digit (1) of the dividend behind the 269 and repeat the process: 2691 / 409

On to step 7:
If we divide 2691 by 409, we get 6 and a remainder of 237.
Record the quotient 6 as the next digit in the result. 
Result so far: 21586.0
The remainder is 237 after subtracting 2454 from 2691.
Include the next digit (6) from the dividend after 237, then repeat: 2376 / 409

Moving on to step 8:
409 goes into 2376 5 times with a remainder of 331.
Record the quotient 5 as the next digit in the result. 
Result so far: 215865.0
The remainder is 331 after subtracting 2045 from 2376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 9:
409 can be fit into 3310 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 215865.8
If we take 3272 away from 3310, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
If we divide 380 by 409, we get 0 and a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 215865.8
The remainder is 380 after subtracting 0 from 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 11:
3800 divided by 409 is 9 with a remainder of 119.
Use 9 as the next digit of our solution. 
Result so far: 215865.809
Subtract 3681 from 3800 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 12:
The number 409 fits into 1190 2 times, leaving a remainder of 372.
The number 2 becomes the next digit in our result. 
Result so far: 215865.8092
Subtract 818 from 1190 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 13:
409 goes into 3720 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 215865.80929
If we subtract 3681 from 3720, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
409 goes into 390 0 times with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 215865.80929
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 15:
If we divide 3900 by 409, we get 9 and a remainder of 219.
The number 9 becomes the next digit in our result. 
Result so far: 215865.8092909
The remainder is 219 after subtracting 3681 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 16:
When dividing 2190 by 409, we get 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 215865.80929095
Subtract 2045 from 2190 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 215865.80929095 with a remainder of 1.45e-07.
