Let's divide 9950429 by 455
The aim is to understand the frequency of 455 in 9950429.

Advancing to step 1:
455 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 455

Let's proceed to step 2:
455 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 455

Step 3:
455 can be fit into 995 2 times, resulting in a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 910 from 995 leaves us with 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 455

Moving on to step 4:
850 divided by 455 is 1 with a remainder of 395.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 455 from 850 and we're left with 395.
Append the next digit (4) from the dividend to 395 and continue with: 3954 / 455

On to step 5:
When dividing 3954 by 455, we get 8 with a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 218.0
Deduct 3640 from 3954 and we're left with 314.
Fetch the next digit (2) from the dividend, attach it to 314 and continue: 3142 / 455

Going ahead to step 6:
If we divide 3142 by 455, we get 6 and a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 2186.0
The remainder is 412 after subtracting 2730 from 3142.
Bring next digit (9) of the dividend behind the 412 and repeat the process: 4129 / 455

Going ahead to step 7:
If we divide 4129 by 455, we get 9 and a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 21869.0
Subtracting 4095 from 4129 leaves us 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.

Moving on to step 8:
If we divide 340 by 455, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 21869.0
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.

Going ahead to step 9:
455 can be fit into 3400 7 times, resulting in a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 21869.07
If we take 3185 away from 3400, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 10:
455 can be fit into 2150 4 times, resulting in a remainder of 330.
The next digit of our result is 4. 
Result so far: 21869.074
Subtracting 1820 from 2150 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
455 goes into 3300 7 times with a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 21869.0747
If we take 3185 away from 3300, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
When dividing 1150 by 455, we get 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 21869.07472
If we take 910 away from 1150, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
When dividing 2400 by 455, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 21869.074725
Subtract 2275 from 2400 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
455 goes into 1250 2 times with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 21869.0747252
The remainder is 340 after subtracting 910 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
455 can be fit into 3400 7 times, resulting in a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 21869.07472527
Subtract 3185 from 3400 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 21869.07472527, with a leftover of 2.15e-07.
