We look at the division of 83898989 by 455 
The aim is to understand the frequency of 455 in 83898989.

Advancing to step 1:
455 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 455

On to step 2:
455 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 455

On to step 3:
455 can be fit into 838 1 times, resulting in a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 455 from 838 to get 383.
Take the next digit (9) from the dividend and append it to 383, then repeat: 3839 / 455

Let's proceed to step 4:
If we divide 3839 by 455, we get 8 and a remainder of 199.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 3640 away from 3839, we end up with 199.
Append the next digit (8) from the dividend to 199 and continue with: 1998 / 455

Moving on to step 5:
455 can be fit into 1998 4 times, resulting in a remainder of 178.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 1820 from 1998, we get 178.
Take the next digit (9) from the dividend and append it to 178, then repeat: 1789 / 455

Advancing to step 6:
455 can be fit into 1789 3 times, resulting in a remainder of 424.
Put 3 as the next digit of the answer. 
Result so far: 1843.0
Subtracting 1365 from 1789 leaves us with 424.
Bring next digit (8) of the dividend behind the 424 and repeat the process: 4248 / 455

Going ahead to step 7:
455 goes into 4248 9 times with a remainder of 153.
Record the quotient 9 as the next digit in the result. 
Result so far: 18439.0
Deduct 4095 from 4248 and we're left with 153.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 455

Moving on to step 8:
The number 455 fits into 1539 3 times, leaving a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 184393.0
Subtracting 1365 from 1539 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 9:
If we divide 1740 by 455, we get 3 and a remainder of 375.
The number 3 becomes the next digit in our result. 
Result so far: 184393.3
If we take 1365 away from 1740, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 10:
455 can be fit into 3750 8 times, resulting in a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 184393.38
If we take 3640 away from 3750, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
If we divide 1100 by 455, we get 2 and a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 184393.382
The remainder is 190 after subtracting 910 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 12:
When dividing 1900 by 455, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 184393.3824
If we take 1820 away from 1900, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
The number 455 fits into 800 1 times, leaving a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 184393.38241
Deduct 455 from 800 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 14:
The number 455 fits into 3450 7 times, leaving a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 184393.382417
If we subtract 3185 from 3450, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 15:
When dividing 2650 by 455, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 184393.3824175
If we subtract 2275 from 2650, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 16:
When dividing 3750 by 455, we get 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 184393.38241758
Subtract 3640 from 3750 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 184393.38241758 with a balance of 1.1e-07.
