23947834 ÷ 409 
The aim is to understand the frequency of 409 in 23947834.

Going ahead to step 1:
2 divided by 409 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 409

On to step 2:
If we divide 23 by 409, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 409

Advancing to step 3:
If we divide 239 by 409, we get 0 and a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Append the next digit (4) from the dividend to 239 and continue with: 2394 / 409

Step 4:
The number 409 fits into 2394 5 times, leaving a remainder of 349.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 2045 away from 2394, we end up with 349.
Grab the next digit (7) from the dividend, add it to 349, then carry on: 3497 / 409

Moving on to step 5:
409 goes into 3497 8 times with a remainder of 225.
The next digit of our result is 8. 
Result so far: 58.0
If we take 3272 away from 3497, we end up with 225.
Include the next digit (8) from the dividend after 225, then repeat: 2258 / 409

On to step 6:
When dividing 2258 by 409, we get 5 with a remainder of 213.
Put 5 as the next digit of the answer. 
Result so far: 585.0
Deduct 2045 from 2258 and we're left with 213.
Fetch the next digit (3) from the dividend, attach it to 213 and continue: 2133 / 409

Advancing to step 7:
When dividing 2133 by 409, we get 5 with a remainder of 88.
The next digit of our result is 5. 
Result so far: 5855.0
Deduct 2045 from 2133 and we're left with 88.
Grab the next digit (4) from the dividend, add it to 88, then carry on: 884 / 409

Moving on to step 8:
If we divide 884 by 409, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 58552.0
Subtracting 818 from 884 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
When dividing 660 by 409, we get 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 58552.1
The remainder is 251 after subtracting 409 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 10:
409 can be fit into 2510 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 58552.16
Subtracting 2454 from 2510 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 409, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 58552.161
Deduct 409 from 560 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 12:
1510 divided by 409 is 3 with a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 58552.1613
Subtract 1227 from 1510 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 13:
409 goes into 2830 6 times with a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 58552.16136
Subtracting 2454 from 2830 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 14:
The number 409 fits into 3760 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 58552.161369
Subtract 3681 from 3760 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 15:
409 can be fit into 790 1 times, resulting in a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 58552.1613691
If we subtract 409 from 790, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 16:
When dividing 3810 by 409, we get 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 58552.16136919
If we take 3681 away from 3810, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

In conclusion, the division gives 58552.16136919 with a balance of 1.29e-07.
