We divide 674198 by 15
The aim is to understand the frequency of 15 in 674198.

Step 1:
6 divided by 15 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Moving on to step 2:
If we divide 67 by 15, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 60 from 67, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 15

Moving on to step 3:
15 can be fit into 74 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 44.0
Subtract 60 from 74 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 15

Going ahead to step 4:
15 goes into 141 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 449.0
Subtract 135 from 141 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 15

On to step 5:
69 divided by 15 is 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4494.0
Subtract 60 from 69 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 15

Step 6:
The number 15 fits into 98 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 44946.0
Deduct 90 from 98 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 15 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 44946.5
Subtract 75 from 80 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 44946.53
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 44946.533
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 44946.533, and the remainder is 0.0005.
