We divide 42074486 by 409
The aim is to understand the frequency of 409 in 42074486.

Let's proceed to step 1:
4 divided by 409 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 409

On to step 2:
42 divided by 409 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 409

On to step 3:
409 can be fit into 420 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 409 from 420 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 409

Step 4:
If we divide 117 by 409, we get 0 and a remainder of 117.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 117, we get 117.
Fetch the next digit (4) from the dividend, attach it to 117 and continue: 1174 / 409

On to step 5:
409 goes into 1174 2 times with a remainder of 356.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 818 from 1174, we get 356.
Include the next digit (4) from the dividend after 356, then repeat: 3564 / 409

Moving on to step 6:
When dividing 3564 by 409, we get 8 with a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 1028.0
Subtracting 3272 from 3564 leaves us with 292.
Fetch the next digit (8) from the dividend, attach it to 292 and continue: 2928 / 409

Let's proceed to step 7:
409 can be fit into 2928 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 10287.0
The remainder is 65 after subtracting 2863 from 2928.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 409

Let's proceed to step 8:
409 goes into 656 1 times with a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 102871.0
Subtract 409 from 656 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 9:
2470 divided by 409 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 102871.6
If we take 2454 away from 2470, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
409 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 102871.6
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
409 can be fit into 1600 3 times, resulting in a remainder of 373.
Record the quotient 3 as the next digit in the result. 
Result so far: 102871.603
Subtracting 1227 from 1600 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 12:
409 goes into 3730 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 102871.6039
If we subtract 3681 from 3730, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
409 can be fit into 490 1 times, resulting in a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 102871.60391
Deduct 409 from 490 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 14:
810 divided by 409 is 1 with a remainder of 401.
The next digit of our result is 1. 
Result so far: 102871.603911
If we take 409 away from 810, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Our division results in 102871.603911 with a remaining 4.01e-05.
