453890 ÷ 89 
The aim is to understand the frequency of 89 in 453890.

Advancing to step 1:
89 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 89

Let's proceed to step 2:
When dividing 45 by 89, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 89

Step 3:
89 goes into 453 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 445 from 453 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 89

Let's proceed to step 4:
The number 89 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 89

Going ahead to step 5:
89 goes into 889 9 times with a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 509.0
The remainder is 88 after subtracting 801 from 889.
Grab the next digit (0) from the dividend, add it to 88, then carry on: 880 / 89

On to step 6:
When dividing 880 by 89, we get 9 with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 5099.0
Subtracting 801 from 880 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
790 divided by 89 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 5099.8
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
If we divide 780 by 89, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 5099.88
The remainder is 68 after subtracting 712 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 5099.88, and the remainder is 0.068.
