We look at the division of 89775377 by 303 
The aim is to understand the frequency of 303 in 89775377.

Let's proceed to step 1:
The number 303 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 303

Moving on to step 2:
303 can be fit into 89 0 times, resulting in a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 303

Going ahead to step 3:
If we divide 897 by 303, we get 2 and a remainder of 291.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 606 from 897 leaves us with 291.
Bring next digit (7) of the dividend behind the 291 and repeat the process: 2917 / 303

Step 4:
303 can be fit into 2917 9 times, resulting in a remainder of 190.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 2727 from 2917 and we're left with 190.
Take the next digit (5) from the dividend and append it to 190, then repeat: 1905 / 303

Moving on to step 5:
When dividing 1905 by 303, we get 6 with a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 296.0
Deduct 1818 from 1905 and we're left with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 303

Moving on to step 6:
When dividing 873 by 303, we get 2 with a remainder of 267.
The next digit of our result is 2. 
Result so far: 2962.0
Subtracting 606 from 873 leaves us with 267.
Include the next digit (7) from the dividend after 267, then repeat: 2677 / 303

On to step 7:
The number 303 fits into 2677 8 times, leaving a remainder of 253.
The number 8 becomes the next digit in our result. 
Result so far: 29628.0
Deduct 2424 from 2677 and we're left with 253.
Bring next digit (7) of the dividend behind the 253 and repeat the process: 2537 / 303

Advancing to step 8:
When dividing 2537 by 303, we get 8 with a remainder of 113.
Put 8 as the next digit of the answer. 
Result so far: 296288.0
Subtract 2424 from 2537 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
When dividing 1130 by 303, we get 3 with a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 296288.3
Subtract 909 from 1130 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 10:
303 can be fit into 2210 7 times, resulting in a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 296288.37
Subtracting 2121 from 2210 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
890 divided by 303 is 2 with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 296288.372
If we take 606 away from 890, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 12:
303 goes into 2840 9 times with a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 296288.3729
If we subtract 2727 from 2840, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 13:
If we divide 1130 by 303, we get 3 and a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 296288.37293
If we take 909 away from 1130, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 14:
When dividing 2210 by 303, we get 7 with a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 296288.372937
If we take 2121 away from 2210, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 15:
If we divide 890 by 303, we get 2 and a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 296288.3729372
Subtracting 606 from 890 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 16:
When dividing 2840 by 303, we get 9 with a remainder of 113.
The next digit of our result is 9. 
Result so far: 296288.37293729
If we take 2727 away from 2840, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The quotient of the division is 296288.37293729, and the remainder is 1.13e-07.
