We're dividing 450818 by 89 
The aim is to understand the frequency of 89 in 450818.

Step 1:
4 divided by 89 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 89

Going ahead to step 2:
The number 89 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 89

On to step 3:
The number 89 fits into 450 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 445 from 450 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 89

Going ahead to step 4:
89 goes into 58 0 times with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 89

Step 5:
581 divided by 89 is 6 with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 506.0
The remainder is 47 after subtracting 534 from 581.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 89

Advancing to step 6:
When dividing 478 by 89, we get 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5065.0
Subtract 445 from 478 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
The number 89 fits into 330 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 5065.3
If we subtract 267 from 330, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
89 can be fit into 630 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 5065.37
Subtracting 623 from 630 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
When dividing 70 by 89, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 5065.37
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
89 can be fit into 700 7 times, resulting in a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 5065.3707
If we take 623 away from 700, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
89 goes into 770 8 times with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 5065.37078
Subtracting 712 from 770 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
If we divide 580 by 89, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 5065.370786
Subtract 534 from 580 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
When dividing 460 by 89, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5065.3707865
If we subtract 445 from 460, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
89 goes into 150 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 5065.37078651
If we subtract 89 from 150, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 5065.37078651, with a leftover of 6.1e-08.
