90922911 ÷ 455 
The aim is to understand the frequency of 455 in 90922911.

Step 1:
If we divide 9 by 455, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 455

On to step 2:
455 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 455

Going ahead to step 3:
When dividing 909 by 455, we get 1 with a remainder of 454.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 455 from 909 leaves us with 454.
Include the next digit (2) from the dividend after 454, then repeat: 4542 / 455

On to step 4:
4542 divided by 455 is 9 with a remainder of 447.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 4095 from 4542 leaves us with 447.
Grab the next digit (2) from the dividend, add it to 447, then carry on: 4472 / 455

On to step 5:
If we divide 4472 by 455, we get 9 and a remainder of 377.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Subtract 4095 from 4472 to get 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 455

Moving on to step 6:
3779 divided by 455 is 8 with a remainder of 139.
Use 8 as the next digit of our solution. 
Result so far: 1998.0
Subtracting 3640 from 3779 leaves us with 139.
Append the next digit (1) from the dividend to 139 and continue with: 1391 / 455

Moving on to step 7:
455 can be fit into 1391 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 19983.0
Subtract 1365 from 1391 to get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 455

Advancing to step 8:
When dividing 261 by 455, we get 0 with a remainder of 261.
The number 0 becomes the next digit in our result. 
Result so far: 199830.0
Deduct 0 from 261 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 9:
When dividing 2610 by 455, we get 5 with a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 199830.5
Subtract 2275 from 2610 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 10:
If we divide 3350 by 455, we get 7 and a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 199830.57
Subtract 3185 from 3350 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 11:
The number 455 fits into 1650 3 times, leaving a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 199830.573
Subtract 1365 from 1650 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 12:
455 can be fit into 2850 6 times, resulting in a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 199830.5736
Subtracting 2730 from 2850 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
When dividing 1200 by 455, we get 2 with a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 199830.57362
If we subtract 910 from 1200, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
2900 divided by 455 is 6 with a remainder of 170.
The next digit of our result is 6. 
Result so far: 199830.573626
If we take 2730 away from 2900, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 15:
455 can be fit into 1700 3 times, resulting in a remainder of 335.
Use 3 as the next digit of our solution. 
Result so far: 199830.5736263
If we take 1365 away from 1700, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 16:
3350 divided by 455 is 7 with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 199830.57362637
If we take 3185 away from 3350, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Our division results in 199830.57362637 with a remaining 1.65e-07.
