We're dividing 51718524 by 203 
The aim is to understand the frequency of 203 in 51718524.

Step 1:
203 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 203

Let's proceed to step 2:
203 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 203

Going ahead to step 3:
203 goes into 517 2 times with a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 406 from 517 to get 111.
Bring next digit (1) of the dividend behind the 111 and repeat the process: 1111 / 203

Step 4:
203 goes into 1111 5 times with a remainder of 96.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 1015 from 1111, we get 96.
Take the next digit (8) from the dividend and append it to 96, then repeat: 968 / 203

On to step 5:
The number 203 fits into 968 4 times, leaving a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Deduct 812 from 968 and we're left with 156.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 203

On to step 6:
203 goes into 1565 7 times with a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 2547.0
Subtract 1421 from 1565 to get 144.
Append the next digit (2) from the dividend to 144 and continue with: 1442 / 203

On to step 7:
The number 203 fits into 1442 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 25477.0
If we subtract 1421 from 1442, we get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 203

Advancing to step 8:
When dividing 214 by 203, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 254771.0
If we subtract 203 from 214, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 203, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 254771.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
1100 divided by 203 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 254771.05
Subtracting 1015 from 1100 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
The number 203 fits into 850 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 254771.054
If we take 812 away from 850, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
203 goes into 380 1 times with a remainder of 177.
Put 1 as the next digit of the answer. 
Result so far: 254771.0541
Subtracting 203 from 380 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 13:
When dividing 1770 by 203, we get 8 with a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 254771.05418
If we take 1624 away from 1770, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 14:
The number 203 fits into 1460 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 254771.054187
Deduct 1421 from 1460 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 15:
The number 203 fits into 390 1 times, leaving a remainder of 187.
The next digit of our result is 1. 
Result so far: 254771.0541871
Deduct 203 from 390 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 16:
203 can be fit into 1870 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 254771.05418719
If we take 1827 away from 1870, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 254771.05418719, with a leftover of 4.3e-08.
