We're dividing 33873512 by 203 
The aim is to understand the frequency of 203 in 33873512.

Moving on to step 1:
If we divide 3 by 203, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 203

Going ahead to step 2:
The number 203 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 203

Going ahead to step 3:
When dividing 338 by 203, we get 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 203 from 338, we get 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 203

Step 4:
1357 divided by 203 is 6 with a remainder of 139.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 139 after subtracting 1218 from 1357.
Include the next digit (3) from the dividend after 139, then repeat: 1393 / 203

Let's proceed to step 5:
1393 divided by 203 is 6 with a remainder of 175.
Use 6 as the next digit of our solution. 
Result so far: 166.0
The remainder is 175 after subtracting 1218 from 1393.
Take the next digit (5) from the dividend and append it to 175, then repeat: 1755 / 203

Step 6:
1755 divided by 203 is 8 with a remainder of 131.
Use 8 as the next digit of our solution. 
Result so far: 1668.0
Subtract 1624 from 1755 to get 131.
Bring next digit (1) of the dividend behind the 131 and repeat the process: 1311 / 203

Let's proceed to step 7:
When dividing 1311 by 203, we get 6 with a remainder of 93.
Put 6 as the next digit of the answer. 
Result so far: 16686.0
Subtract 1218 from 1311 to get 93.
Include the next digit (2) from the dividend after 93, then repeat: 932 / 203

Let's proceed to step 8:
203 goes into 932 4 times with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 166864.0
The remainder is 120 after subtracting 812 from 932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
203 goes into 1200 5 times with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 166864.5
If we take 1015 away from 1200, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 10:
203 goes into 1850 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 166864.59
Subtract 1827 from 1850 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
203 goes into 230 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 166864.591
The remainder is 27 after subtracting 203 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
203 goes into 270 1 times with a remainder of 67.
The next digit of our result is 1. 
Result so far: 166864.5911
Subtracting 203 from 270 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 166864.5911 and a remainder of 0.00067.
