We look at the division of 152225 by 74 
The aim is to understand the frequency of 74 in 152225.

Let's proceed to step 1:
When dividing 1 by 74, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 74

On to step 2:
74 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 74

Step 3:
If we divide 152 by 74, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 148 from 152 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 74

Advancing to step 4:
The number 74 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 74

Advancing to step 5:
74 goes into 422 5 times with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 370 from 422 leaves us with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 74

Going ahead to step 6:
The number 74 fits into 525 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 2057.0
Deduct 518 from 525 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 74, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 2057.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
74 goes into 700 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 2057.09
Subtracting 666 from 700 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
When dividing 340 by 74, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 2057.094
Subtract 296 from 340 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
If we divide 440 by 74, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 2057.0945
If we take 370 away from 440, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
The number 74 fits into 700 9 times, leaving a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 2057.09459
The remainder is 34 after subtracting 666 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
340 divided by 74 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 2057.094594
Subtract 296 from 340 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
If we divide 440 by 74, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 2057.0945945
The remainder is 70 after subtracting 370 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
74 can be fit into 700 9 times, resulting in a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 2057.09459459
Deduct 666 from 700 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 2057.09459459 and a remainder of 3.4e-08.
