We're dividing 406816 by 89 
The aim is to understand the frequency of 89 in 406816.

Let's proceed to step 1:
If we divide 4 by 89, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 89

Moving on to step 2:
If we divide 40 by 89, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 89

Going ahead to step 3:
406 divided by 89 is 4 with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 356 from 406 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 89

On to step 4:
The number 89 fits into 508 5 times, leaving a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 445 from 508 and we're left with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 89

Let's proceed to step 5:
The number 89 fits into 631 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 457.0
Subtract 623 from 631 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 89

Step 6:
89 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 4570.0
Deduct 0 from 86 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 7:
89 can be fit into 860 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 4570.9
If we take 801 away from 860, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
The number 89 fits into 590 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 4570.96
The remainder is 56 after subtracting 534 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
89 goes into 560 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 4570.966
The remainder is 26 after subtracting 534 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 4570.966, and the remainder is 0.0026.
