We're dividing 50172599 by 303 
The aim is to understand the frequency of 303 in 50172599.

Step 1:
303 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 303

Moving on to step 2:
If we divide 50 by 303, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 303

Moving on to step 3:
303 can be fit into 501 1 times, resulting in a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 303 from 501 and we're left with 198.
Grab the next digit (7) from the dividend, add it to 198, then carry on: 1987 / 303

Let's proceed to step 4:
303 goes into 1987 6 times with a remainder of 169.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 1818 from 1987 leaves us with 169.
Append the next digit (2) from the dividend to 169 and continue with: 1692 / 303

Going ahead to step 5:
The number 303 fits into 1692 5 times, leaving a remainder of 177.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we take 1515 away from 1692, we end up with 177.
Append the next digit (5) from the dividend to 177 and continue with: 1775 / 303

Step 6:
When dividing 1775 by 303, we get 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
If we take 1515 away from 1775, we end up with 260.
Bring next digit (9) of the dividend behind the 260 and repeat the process: 2609 / 303

Moving on to step 7:
2609 divided by 303 is 8 with a remainder of 185.
Write down 8 as next digit of the result. 
Result so far: 16558.0
If we take 2424 away from 2609, we end up with 185.
Include the next digit (9) from the dividend after 185, then repeat: 1859 / 303

Let's proceed to step 8:
303 goes into 1859 6 times with a remainder of 41.
The next digit of our result is 6. 
Result so far: 165586.0
The remainder is 41 after subtracting 1818 from 1859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
410 divided by 303 is 1 with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 165586.1
If we take 303 away from 410, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 10:
303 can be fit into 1070 3 times, resulting in a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 165586.13
Deduct 909 from 1070 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 11:
If we divide 1610 by 303, we get 5 and a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 165586.135
Subtracting 1515 from 1610 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 12:
The number 303 fits into 950 3 times, leaving a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 165586.1353
Deduct 909 from 950 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
The number 303 fits into 410 1 times, leaving a remainder of 107.
The next digit of our result is 1. 
Result so far: 165586.13531
If we subtract 303 from 410, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 14:
303 can be fit into 1070 3 times, resulting in a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 165586.135313
Subtract 909 from 1070 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 15:
303 can be fit into 1610 5 times, resulting in a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 165586.1353135
Subtracting 1515 from 1610 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 16:
When dividing 950 by 303, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 165586.13531353
The remainder is 41 after subtracting 909 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The quotient of the division is 165586.13531353, and the remainder is 4.1e-08.
