We're dividing 68663620 by 903 
The aim is to understand the frequency of 903 in 68663620.

Advancing to step 1:
The number 903 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 903

Going ahead to step 2:
903 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 903

Moving on to step 3:
The number 903 fits into 686 0 times, leaving a remainder of 686.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 686 after subtracting 0 from 686.
Grab the next digit (6) from the dividend, add it to 686, then carry on: 6866 / 903

Going ahead to step 4:
When dividing 6866 by 903, we get 7 with a remainder of 545.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6321 from 6866 to get 545.
Append the next digit (3) from the dividend to 545 and continue with: 5453 / 903

Step 5:
903 goes into 5453 6 times with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we take 5418 away from 5453, we end up with 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 903

On to step 6:
903 can be fit into 356 0 times, resulting in a remainder of 356.
Write down 0 as next digit of the result. 
Result so far: 760.0
If we subtract 0 from 356, we get 356.
Fetch the next digit (2) from the dividend, attach it to 356 and continue: 3562 / 903

Moving on to step 7:
If we divide 3562 by 903, we get 3 and a remainder of 853.
Write down 3 as next digit of the result. 
Result so far: 7603.0
Subtract 2709 from 3562 to get 853.
Bring next digit (0) of the dividend behind the 853 and repeat the process: 8530 / 903

Advancing to step 8:
The number 903 fits into 8530 9 times, leaving a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 76039.0
Subtract 8127 from 8530 to get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 9:
When dividing 4030 by 903, we get 4 with a remainder of 418.
Use 4 as the next digit of our solution. 
Result so far: 76039.4
The remainder is 418 after subtracting 3612 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
If we divide 4180 by 903, we get 4 and a remainder of 568.
Use 4 as the next digit of our solution. 
Result so far: 76039.44
If we take 3612 away from 4180, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 76039.44 with a remainder of 0.568.
