We're dividing 45163931 by 404 
The aim is to understand the frequency of 404 in 45163931.

Let's proceed to step 1:
When dividing 4 by 404, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 404

On to step 2:
When dividing 45 by 404, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 404

Advancing to step 3:
404 goes into 451 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 404 from 451, we get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 404

On to step 4:
404 goes into 476 1 times with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 404 from 476 and we're left with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 404

Moving on to step 5:
When dividing 723 by 404, we get 1 with a remainder of 319.
The next digit of our result is 1. 
Result so far: 111.0
Subtract 404 from 723 to get 319.
Append the next digit (9) from the dividend to 319 and continue with: 3199 / 404

Step 6:
404 can be fit into 3199 7 times, resulting in a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 1117.0
If we subtract 2828 from 3199, we get 371.
Take the next digit (3) from the dividend and append it to 371, then repeat: 3713 / 404

Advancing to step 7:
When dividing 3713 by 404, we get 9 with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 11179.0
If we take 3636 away from 3713, we end up with 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 404

On to step 8:
404 can be fit into 771 1 times, resulting in a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 111791.0
If we take 404 away from 771, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 9:
404 can be fit into 3670 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 111791.9
If we take 3636 away from 3670, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
The number 404 fits into 340 0 times, leaving a remainder of 340.
The next digit of our result is 0. 
Result so far: 111791.9
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
3400 divided by 404 is 8 with a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 111791.908
If we take 3232 away from 3400, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
The number 404 fits into 1680 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 111791.9084
Deduct 1616 from 1680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
The number 404 fits into 640 1 times, leaving a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 111791.90841
The remainder is 236 after subtracting 404 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 14:
404 goes into 2360 5 times with a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 111791.908415
Deduct 2020 from 2360 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
When dividing 3400 by 404, we get 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 111791.9084158
Subtracting 3232 from 3400 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 16:
If we divide 1680 by 404, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 111791.90841584
If we subtract 1616 from 1680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 111791.90841584 with a balance of 6.4e-08.
