Let's divide 376444 by 15
The aim is to understand the frequency of 15 in 376444.

Let's proceed to step 1:
15 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 15

Going ahead to step 2:
15 goes into 37 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 7 after subtracting 30 from 37.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 15

Going ahead to step 3:
The number 15 fits into 76 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 75 from 76, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 15

Advancing to step 4:
The number 15 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 15

Advancing to step 5:
When dividing 144 by 15, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 2509.0
Subtracting 135 from 144 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 15

Moving on to step 6:
If we divide 94 by 15, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 25096.0
If we take 90 away from 94, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 15, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 25096.2
If we take 30 away from 40, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 25096.26
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 25096.266
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 25096.266, and the remainder is 0.001.
