We look at the division of 33064395 by 987 
The aim is to understand the frequency of 987 in 33064395.

Going ahead to step 1:
When dividing 3 by 987, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 987

On to step 2:
33 divided by 987 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 987

Step 3:
987 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 330 to get 330.
Append the next digit (6) from the dividend to 330 and continue with: 3306 / 987

Advancing to step 4:
The number 987 fits into 3306 3 times, leaving a remainder of 345.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2961 from 3306 leaves us with 345.
Append the next digit (4) from the dividend to 345 and continue with: 3454 / 987

Advancing to step 5:
987 can be fit into 3454 3 times, resulting in a remainder of 493.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 493 after subtracting 2961 from 3454.
Take the next digit (3) from the dividend and append it to 493, then repeat: 4933 / 987

Going ahead to step 6:
987 goes into 4933 4 times with a remainder of 985.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
Subtract 3948 from 4933 to get 985.
Take the next digit (9) from the dividend and append it to 985, then repeat: 9859 / 987

Let's proceed to step 7:
When dividing 9859 by 987, we get 9 with a remainder of 976.
Put 9 as the next digit of the answer. 
Result so far: 3349.0
Subtract 8883 from 9859 to get 976.
Fetch the next digit (5) from the dividend, attach it to 976 and continue: 9765 / 987

Let's proceed to step 8:
When dividing 9765 by 987, we get 9 with a remainder of 882.
Use 9 as the next digit of our solution. 
Result so far: 33499.0
If we take 8883 away from 9765, we end up with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

On to step 9:
8820 divided by 987 is 8 with a remainder of 924.
Write down 8 as next digit of the result. 
Result so far: 33499.8
If we subtract 7896 from 8820, we get 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

On to step 10:
The number 987 fits into 9240 9 times, leaving a remainder of 357.
The number 9 becomes the next digit in our result. 
Result so far: 33499.89
Deduct 8883 from 9240 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Let's proceed to step 11:
The number 987 fits into 3570 3 times, leaving a remainder of 609.
Put 3 as the next digit of the answer. 
Result so far: 33499.893
If we take 2961 away from 3570, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 12:
The number 987 fits into 6090 6 times, leaving a remainder of 168.
The next digit of our result is 6. 
Result so far: 33499.8936
If we take 5922 away from 6090, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 13:
The number 987 fits into 1680 1 times, leaving a remainder of 693.
The next digit of our result is 1. 
Result so far: 33499.89361
The remainder is 693 after subtracting 987 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Let's proceed to step 14:
If we divide 6930 by 987, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 33499.893617
If we subtract 6909 from 6930, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 15:
210 divided by 987 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 33499.893617
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 16:
The number 987 fits into 2100 2 times, leaving a remainder of 126.
The next digit of our result is 2. 
Result so far: 33499.89361702
Subtract 1974 from 2100 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 33499.89361702 with a remainder of 1.26e-07.
