We look at the division of 30936603 by 148 
The aim is to understand the frequency of 148 in 30936603.

Moving on to step 1:
The number 148 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 148

Going ahead to step 2:
When dividing 30 by 148, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 148

Step 3:
309 divided by 148 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 296 from 309, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 148

Let's proceed to step 4:
133 divided by 148 is 0 with a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 133, we end up with 133.
Include the next digit (6) from the dividend after 133, then repeat: 1336 / 148

On to step 5:
If we divide 1336 by 148, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we take 1332 away from 1336, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 148

Advancing to step 6:
148 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 2090.0
The remainder is 46 after subtracting 0 from 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 148

On to step 7:
148 goes into 460 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 20903.0
The remainder is 16 after subtracting 444 from 460.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 148

On to step 8:
If we divide 163 by 148, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 209031.0
If we subtract 148 from 163, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
If we divide 150 by 148, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 209031.1
The remainder is 2 after subtracting 148 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 148 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 209031.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 148, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 209031.101
Deduct 148 from 200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 148, we get 3 and a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 209031.1013
If we subtract 444 from 520, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
148 can be fit into 760 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 209031.10135
If we subtract 740 from 760, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
200 divided by 148 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 209031.101351
Subtracting 148 from 200 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 15:
If we divide 520 by 148, we get 3 and a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 209031.1013513
Subtracting 444 from 520 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 16:
148 goes into 760 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 209031.10135135
Subtracting 740 from 760 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 209031.10135135 with a remainder of 2e-08.
