We're dividing 9484509 by 455 
The aim is to understand the frequency of 455 in 9484509.

Going ahead to step 1:
455 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 455

On to step 2:
The number 455 fits into 94 0 times, leaving a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 94, we end up with 94.
Bring next digit (8) of the dividend behind the 94 and repeat the process: 948 / 455

Going ahead to step 3:
The number 455 fits into 948 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 910 from 948 and we're left with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 455

On to step 4:
455 goes into 384 0 times with a remainder of 384.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 384 after subtracting 0 from 384.
Append the next digit (5) from the dividend to 384 and continue with: 3845 / 455

Going ahead to step 5:
455 can be fit into 3845 8 times, resulting in a remainder of 205.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 3640 from 3845 to get 205.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 455

Moving on to step 6:
455 can be fit into 2050 4 times, resulting in a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 2084.0
Deduct 1820 from 2050 and we're left with 230.
Include the next digit (9) from the dividend after 230, then repeat: 2309 / 455

On to step 7:
If we divide 2309 by 455, we get 5 and a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 20845.0
The remainder is 34 after subtracting 2275 from 2309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
455 goes into 340 0 times with a remainder of 340.
The next digit of our result is 0. 
Result so far: 20845.0
The remainder is 340 after subtracting 0 from 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 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: 20845.07
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:
When dividing 2150 by 455, we get 4 with a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 20845.074
Deduct 1820 from 2150 and we're left 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:
If we divide 3300 by 455, we get 7 and a remainder of 115.
The next digit of our result is 7. 
Result so far: 20845.0747
Subtract 3185 from 3300 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 12:
The number 455 fits into 1150 2 times, leaving a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 20845.07472
Deduct 910 from 1150 and we're left 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.

Step 13:
When dividing 2400 by 455, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 20845.074725
The remainder is 125 after subtracting 2275 from 2400.
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 can be fit into 1250 2 times, resulting in a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 20845.0747252
Subtract 910 from 1250 to get 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 15:
When dividing 3400 by 455, we get 7 with a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 20845.07472527
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 quotient of the division is 20845.07472527, and the remainder is 2.15e-07.
