Let's divide 26613089 by 987
The aim is to understand the frequency of 987 in 26613089.

Advancing to step 1:
The number 987 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 987

Advancing to step 2:
The number 987 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 987

Step 3:
987 can be fit into 266 0 times, resulting in a remainder of 266.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 266 leaves us with 266.
Fetch the next digit (1) from the dividend, attach it to 266 and continue: 2661 / 987

Advancing to step 4:
When dividing 2661 by 987, we get 2 with a remainder of 687.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1974 from 2661 to get 687.
Include the next digit (3) from the dividend after 687, then repeat: 6873 / 987

Step 5:
6873 divided by 987 is 6 with a remainder of 951.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 5922 from 6873 leaves us with 951.
Include the next digit (0) from the dividend after 951, then repeat: 9510 / 987

Moving on to step 6:
987 can be fit into 9510 9 times, resulting in a remainder of 627.
Use 9 as the next digit of our solution. 
Result so far: 269.0
Subtract 8883 from 9510 to get 627.
Fetch the next digit (8) from the dividend, attach it to 627 and continue: 6278 / 987

Advancing to step 7:
987 can be fit into 6278 6 times, resulting in a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 2696.0
Subtracting 5922 from 6278 leaves us with 356.
Append the next digit (9) from the dividend to 356 and continue with: 3569 / 987

On to step 8:
The number 987 fits into 3569 3 times, leaving a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 26963.0
Subtract 2961 from 3569 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 9:
987 can be fit into 6080 6 times, resulting in a remainder of 158.
The next digit of our result is 6. 
Result so far: 26963.6
The remainder is 158 after subtracting 5922 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
987 can be fit into 1580 1 times, resulting in a remainder of 593.
Use 1 as the next digit of our solution. 
Result so far: 26963.61
Subtract 987 from 1580 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Moving on to step 11:
5930 divided by 987 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 26963.616
Deduct 5922 from 5930 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
987 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 26963.616
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
987 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 26963.616
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 26963.616 with a remaining 0.0008.
