We look at the division of 389374 by 89 
The aim is to understand the frequency of 89 in 389374.

On to step 1:
3 divided by 89 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 89

Advancing to step 2:
89 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 89

Moving on to step 3:
If we divide 389 by 89, we get 4 and a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 356 from 389, we get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 89

Let's proceed to step 4:
89 can be fit into 333 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 267 from 333 to get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 89

Step 5:
89 can be fit into 667 7 times, resulting in a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 437.0
If we subtract 623 from 667, we get 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 89

Step 6:
When dividing 444 by 89, we get 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 4374.0
If we subtract 356 from 444, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 7:
If we divide 880 by 89, we get 9 and a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 4374.9
If we take 801 away from 880, we end up 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.

Moving on to step 8:
790 divided by 89 is 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 4374.98
If we subtract 712 from 790, we 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 9:
89 can be fit into 780 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 4374.988
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.

In conclusion, the division gives 4374.988 with a balance of 0.0068.
