821328 ÷ 89 
The aim is to understand the frequency of 89 in 821328.

Advancing to step 1:
8 divided by 89 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 89

Step 2:
If we divide 82 by 89, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 89

Step 3:
If we divide 821 by 89, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 20 after subtracting 801 from 821.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 89

Let's proceed to step 4:
89 can be fit into 203 2 times, resulting in a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 25 after subtracting 178 from 203.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 89

Advancing to step 5:
252 divided by 89 is 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 922.0
Subtract 178 from 252 to get 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 89

Step 6:
When dividing 748 by 89, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9228.0
If we subtract 712 from 748, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 89 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 9228.4
If we take 356 away from 360, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
89 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9228.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 89 fits into 400 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 9228.404
Subtracting 356 from 400 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 89, we get 4 and a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 9228.4044
The remainder is 84 after subtracting 356 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 9228.4044, with a leftover of 0.00084.
