We're dividing 45341837 by 903 
The aim is to understand the frequency of 903 in 45341837.

Moving on to step 1:
903 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 903

Let's proceed to step 2:
When dividing 45 by 903, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 903

Let's proceed to step 3:
The number 903 fits into 453 0 times, leaving a remainder of 453.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 453 leaves us with 453.
Take the next digit (4) from the dividend and append it to 453, then repeat: 4534 / 903

Moving on to step 4:
When dividing 4534 by 903, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 19 after subtracting 4515 from 4534.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 903

Going ahead to step 5:
903 can be fit into 191 0 times, resulting in a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 191 to get 191.
Fetch the next digit (8) from the dividend, attach it to 191 and continue: 1918 / 903

Moving on to step 6:
The number 903 fits into 1918 2 times, leaving a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 502.0
If we subtract 1806 from 1918, we get 112.
Append the next digit (3) from the dividend to 112 and continue with: 1123 / 903

Let's proceed to step 7:
903 can be fit into 1123 1 times, resulting in a remainder of 220.
The next digit of our result is 1. 
Result so far: 5021.0
If we take 903 away from 1123, we end up with 220.
Include the next digit (7) from the dividend after 220, then repeat: 2207 / 903

Moving on to step 8:
When dividing 2207 by 903, we get 2 with a remainder of 401.
Use 2 as the next digit of our solution. 
Result so far: 50212.0
Subtract 1806 from 2207 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 9:
If we divide 4010 by 903, we get 4 and a remainder of 398.
The number 4 becomes the next digit in our result. 
Result so far: 50212.4
If we subtract 3612 from 4010, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 10:
When dividing 3980 by 903, we get 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 50212.44
The remainder is 368 after subtracting 3612 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 50212.44 with a remainder of 0.368.
