We look at the division of 4548555 by 989 
The aim is to understand the frequency of 989 in 4548555.

Step 1:
989 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 989

Going ahead to step 2:
If we divide 45 by 989, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 989

Step 3:
If we divide 454 by 989, we get 0 and a remainder of 454.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 454 to get 454.
Append the next digit (8) from the dividend to 454 and continue with: 4548 / 989

Going ahead to step 4:
If we divide 4548 by 989, we get 4 and a remainder of 592.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3956 away from 4548, we end up with 592.
Take the next digit (5) from the dividend and append it to 592, then repeat: 5925 / 989

Advancing to step 5:
989 goes into 5925 5 times with a remainder of 980.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 4945 from 5925, we get 980.
Grab the next digit (5) from the dividend, add it to 980, then carry on: 9805 / 989

Advancing to step 6:
989 goes into 9805 9 times with a remainder of 904.
Write down 9 as next digit of the result. 
Result so far: 459.0
Subtracting 8901 from 9805 leaves us with 904.
Fetch the next digit (5) from the dividend, attach it to 904 and continue: 9045 / 989

Let's proceed to step 7:
When dividing 9045 by 989, we get 9 with a remainder of 144.
The number 9 becomes the next digit in our result. 
Result so far: 4599.0
The remainder is 144 after subtracting 8901 from 9045.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 8:
The number 989 fits into 1440 1 times, leaving a remainder of 451.
Put 1 as the next digit of the answer. 
Result so far: 4599.1
The remainder is 451 after subtracting 989 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 9:
989 goes into 4510 4 times with a remainder of 554.
Use 4 as the next digit of our solution. 
Result so far: 4599.14
Subtract 3956 from 4510 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 10:
989 can be fit into 5540 5 times, resulting in a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 4599.145
If we subtract 4945 from 5540, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 11:
989 can be fit into 5950 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 4599.1456
Deduct 5934 from 5950 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
If we divide 160 by 989, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 4599.1456
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 989, we get 1 and a remainder of 611.
Write down 1 as next digit of the result. 
Result so far: 4599.145601
Subtract 989 from 1600 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 14:
989 can be fit into 6110 6 times, resulting in a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 4599.1456016
If we subtract 5934 from 6110, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
989 goes into 1760 1 times with a remainder of 771.
The number 1 becomes the next digit in our result. 
Result so far: 4599.14560161
The remainder is 771 after subtracting 989 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

The final result is 4599.14560161 with a remainder of 7.71e-07.
