We look at the division of 46378 by 89 
The aim is to understand the frequency of 89 in 46378.

Going ahead to step 1:
If we divide 4 by 89, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 89

Moving on to step 2:
89 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 89

Let's proceed to step 3:
When dividing 463 by 89, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 18 after subtracting 445 from 463.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 89

Advancing to step 4:
If we divide 187 by 89, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 178 away from 187, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 89

Moving on to step 5:
When dividing 98 by 89, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
The remainder is 9 after subtracting 89 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
89 can be fit into 90 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.1
The remainder is 1 after subtracting 89 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 89, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 521.1
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 89, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 521.101
Subtract 89 from 100 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 521.1011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 521.1011 and a remainder of 0.00021.
