Let's divide 51546511 by 303
The aim is to understand the frequency of 303 in 51546511.

Let's proceed to step 1:
The number 303 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 303

Going ahead to step 2:
51 divided by 303 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 303

Advancing to step 3:
303 goes into 515 1 times with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 303 away from 515, we end up with 212.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 303

Moving on to step 4:
When dividing 2124 by 303, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2121 from 2124, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 303

Going ahead to step 5:
The number 303 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 170.0
Subtract 0 from 36 to get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 303

Going ahead to step 6:
When dividing 365 by 303, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 1701.0
The remainder is 62 after subtracting 303 from 365.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 303

Moving on to step 7:
621 divided by 303 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 17012.0
Subtracting 606 from 621 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 303

Step 8:
303 goes into 151 0 times with a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 170120.0
Subtract 0 from 151 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 9:
When dividing 1510 by 303, we get 4 with a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 170120.4
Deduct 1212 from 1510 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 10:
2980 divided by 303 is 9 with a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 170120.49
Subtracting 2727 from 2980 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 11:
2530 divided by 303 is 8 with a remainder of 106.
The next digit of our result is 8. 
Result so far: 170120.498
Deduct 2424 from 2530 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
303 goes into 1060 3 times with a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 170120.4983
If we subtract 909 from 1060, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 13:
The number 303 fits into 1510 4 times, leaving a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 170120.49834
Subtract 1212 from 1510 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 14:
303 can be fit into 2980 9 times, resulting in a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 170120.498349
Deduct 2727 from 2980 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 15:
2530 divided by 303 is 8 with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 170120.4983498
Subtract 2424 from 2530 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 16:
303 goes into 1060 3 times with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 170120.49834983
If we subtract 909 from 1060, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 170120.49834983, with a leftover of 1.51e-07.
