We look at the division of 10933628 by 538 
The aim is to understand the frequency of 538 in 10933628.

Going ahead to step 1:
If we divide 1 by 538, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 538

On to step 2:
When dividing 10 by 538, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 538

Going ahead to step 3:
109 divided by 538 is 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 109 leaves us with 109.
Bring next digit (3) of the dividend behind the 109 and repeat the process: 1093 / 538

Going ahead to step 4:
538 goes into 1093 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1076 away from 1093, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 538

Let's proceed to step 5:
When dividing 173 by 538, we get 0 with a remainder of 173.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 173 to get 173.
Grab the next digit (6) from the dividend, add it to 173, then carry on: 1736 / 538

On to step 6:
538 goes into 1736 3 times with a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Deduct 1614 from 1736 and we're left with 122.
Include the next digit (2) from the dividend after 122, then repeat: 1222 / 538

Step 7:
The number 538 fits into 1222 2 times, leaving a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 2032.0
Subtracting 1076 from 1222 leaves us with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 538

Advancing to step 8:
538 goes into 1468 2 times with a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 20322.0
Subtract 1076 from 1468 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 9:
If we divide 3920 by 538, we get 7 and a remainder of 154.
Write down 7 as next digit of the result. 
Result so far: 20322.7
If we subtract 3766 from 3920, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 10:
If we divide 1540 by 538, we get 2 and a remainder of 464.
Use 2 as the next digit of our solution. 
Result so far: 20322.72
If we take 1076 away from 1540, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 11:
If we divide 4640 by 538, we get 8 and a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 20322.728
If we subtract 4304 from 4640, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
538 goes into 3360 6 times with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 20322.7286
The remainder is 132 after subtracting 3228 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 13:
538 can be fit into 1320 2 times, resulting in a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 20322.72862
Subtracting 1076 from 1320 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 14:
If we divide 2440 by 538, we get 4 and a remainder of 288.
The next digit of our result is 4. 
Result so far: 20322.728624
Deduct 2152 from 2440 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 15:
If we divide 2880 by 538, we get 5 and a remainder of 190.
The next digit of our result is 5. 
Result so far: 20322.7286245
Deduct 2690 from 2880 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
The number 538 fits into 1900 3 times, leaving a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 20322.72862453
Subtract 1614 from 1900 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final outcome is 20322.72862453, with a leftover of 2.86e-07.
