We're dividing 73710394 by 903 
The aim is to understand the frequency of 903 in 73710394.

Step 1:
7 divided by 903 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 903

Advancing to step 2:
903 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 903

Advancing to step 3:
The number 903 fits into 737 0 times, leaving a remainder of 737.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 737, we get 737.
Take the next digit (1) from the dividend and append it to 737, then repeat: 7371 / 903

On to step 4:
The number 903 fits into 7371 8 times, leaving a remainder of 147.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 7224 from 7371, we get 147.
Append the next digit (0) from the dividend to 147 and continue with: 1470 / 903

On to step 5:
The number 903 fits into 1470 1 times, leaving a remainder of 567.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtracting 903 from 1470 leaves us with 567.
Fetch the next digit (3) from the dividend, attach it to 567 and continue: 5673 / 903

Moving on to step 6:
When dividing 5673 by 903, we get 6 with a remainder of 255.
The number 6 becomes the next digit in our result. 
Result so far: 816.0
Deduct 5418 from 5673 and we're left with 255.
Grab the next digit (9) from the dividend, add it to 255, then carry on: 2559 / 903

Step 7:
When dividing 2559 by 903, we get 2 with a remainder of 753.
Record the quotient 2 as the next digit in the result. 
Result so far: 8162.0
Subtract 1806 from 2559 to get 753.
Fetch the next digit (4) from the dividend, attach it to 753 and continue: 7534 / 903

Going ahead to step 8:
The number 903 fits into 7534 8 times, leaving a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 81628.0
Deduct 7224 from 7534 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 9:
903 can be fit into 3100 3 times, resulting in a remainder of 391.
The next digit of our result is 3. 
Result so far: 81628.3
The remainder is 391 after subtracting 2709 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 10:
If we divide 3910 by 903, we get 4 and a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 81628.34
Subtracting 3612 from 3910 leaves us 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 11:
When dividing 2980 by 903, we get 3 with a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 81628.343
Subtract 2709 from 2980 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 12:
The number 903 fits into 2710 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 81628.3433
If we take 2709 away from 2710, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 81628.3433, with a leftover of 1e-05.
