We're dividing 738349 by 538 
The aim is to understand the frequency of 538 in 738349.

Advancing to step 1:
When dividing 7 by 538, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 538

Going ahead to step 2:
When dividing 73 by 538, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 538

On to step 3:
738 divided by 538 is 1 with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 538 from 738, we get 200.
Take the next digit (3) from the dividend and append it to 200, then repeat: 2003 / 538

Going ahead to step 4:
538 goes into 2003 3 times with a remainder of 389.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1614 from 2003 leaves us with 389.
Fetch the next digit (4) from the dividend, attach it to 389 and continue: 3894 / 538

Advancing to step 5:
The number 538 fits into 3894 7 times, leaving a remainder of 128.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Subtract 3766 from 3894 to get 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 538

Going ahead to step 6:
538 can be fit into 1289 2 times, resulting in a remainder of 213.
The number 2 becomes the next digit in our result. 
Result so far: 1372.0
Subtract 1076 from 1289 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 7:
If we divide 2130 by 538, we get 3 and a remainder of 516.
The number 3 becomes the next digit in our result. 
Result so far: 1372.3
If we subtract 1614 from 2130, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 8:
5160 divided by 538 is 9 with a remainder of 318.
Use 9 as the next digit of our solution. 
Result so far: 1372.39
If we take 4842 away from 5160, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 9:
538 can be fit into 3180 5 times, resulting in a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 1372.395
Subtracting 2690 from 3180 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
The number 538 fits into 4900 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 1372.3959
Subtract 4842 from 4900 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
538 goes into 580 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1372.39591
Subtracting 538 from 580 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
The number 538 fits into 420 0 times, leaving a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 1372.39591
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 13:
The number 538 fits into 4200 7 times, leaving a remainder of 434.
Record the quotient 7 as the next digit in the result. 
Result so far: 1372.3959107
Subtract 3766 from 4200 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 14:
When dividing 4340 by 538, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 1372.39591078
If we take 4304 away from 4340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 1372.39591078 and a remainder of 3.6e-08.
