We look at the division of 81846950 by 903 
The aim is to understand the frequency of 903 in 81846950.

Moving on to step 1:
If we divide 8 by 903, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 903

Step 2:
903 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 903

On to step 3:
If we divide 818 by 903, we get 0 and a remainder of 818.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 818, we end up with 818.
Bring next digit (4) of the dividend behind the 818 and repeat the process: 8184 / 903

Step 4:
If we divide 8184 by 903, we get 9 and a remainder of 57.
The next digit of our result is 9. 
Result so far: 9.0
If we take 8127 away from 8184, we end up with 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 903

Going ahead to step 5:
903 goes into 576 0 times with a remainder of 576.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we take 0 away from 576, we end up with 576.
Take the next digit (9) from the dividend and append it to 576, then repeat: 5769 / 903

Moving on to step 6:
903 goes into 5769 6 times with a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 906.0
If we take 5418 away from 5769, we end up with 351.
Include the next digit (5) from the dividend after 351, then repeat: 3515 / 903

Advancing to step 7:
903 can be fit into 3515 3 times, resulting in a remainder of 806.
Write down 3 as next digit of the result. 
Result so far: 9063.0
The remainder is 806 after subtracting 2709 from 3515.
Append the next digit (0) from the dividend to 806 and continue with: 8060 / 903

Step 8:
903 goes into 8060 8 times with a remainder of 836.
The next digit of our result is 8. 
Result so far: 90638.0
The remainder is 836 after subtracting 7224 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Advancing to step 9:
903 can be fit into 8360 9 times, resulting in a remainder of 233.
Put 9 as the next digit of the answer. 
Result so far: 90638.9
Deduct 8127 from 8360 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 10:
2330 divided by 903 is 2 with a remainder of 524.
The number 2 becomes the next digit in our result. 
Result so far: 90638.92
If we take 1806 away from 2330, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 11:
When dividing 5240 by 903, we get 5 with a remainder of 725.
Record the quotient 5 as the next digit in the result. 
Result so far: 90638.925
Subtract 4515 from 5240 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 12:
7250 divided by 903 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 90638.9258
Subtract 7224 from 7250 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
If we divide 260 by 903, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 90638.9258
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 14:
If we divide 2600 by 903, we get 2 and a remainder of 794.
Record the quotient 2 as the next digit in the result. 
Result so far: 90638.925802
The remainder is 794 after subtracting 1806 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Moving on to step 15:
The number 903 fits into 7940 8 times, leaving a remainder of 716.
Put 8 as the next digit of the answer. 
Result so far: 90638.9258028
Subtracting 7224 from 7940 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Advancing to step 16:
903 can be fit into 7160 7 times, resulting in a remainder of 839.
The number 7 becomes the next digit in our result. 
Result so far: 90638.92580287
Subtracting 6321 from 7160 leaves us with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

The final outcome is 90638.92580287, with a leftover of 8.39e-07.
