Let's divide 663450 by 41
The aim is to understand the frequency of 41 in 663450.

Going ahead to step 1:
41 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 41

Advancing to step 2:
The number 41 fits into 66 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 41 from 66 leaves us with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 41

Advancing to step 3:
When dividing 253 by 41, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 7 after subtracting 246 from 253.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 41

Moving on to step 4:
If we divide 74 by 41, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 161.0
Deduct 41 from 74 and we're left with 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 41

Step 5:
41 can be fit into 335 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1618.0
The remainder is 7 after subtracting 328 from 335.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 41

Going ahead to step 6:
70 divided by 41 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 16181.0
Deduct 41 from 70 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 41 fits into 290 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 16181.7
If we subtract 287 from 290, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
If we divide 30 by 41, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 16181.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
41 can be fit into 300 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 16181.707
Deduct 287 from 300 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 41 fits into 130 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 16181.7073
If we subtract 123 from 130, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
41 can be fit into 70 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 16181.70731
The remainder is 29 after subtracting 41 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
290 divided by 41 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 16181.707317
Subtract 287 from 290 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
If we divide 30 by 41, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 16181.707317
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
If we divide 300 by 41, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 16181.70731707
Subtract 287 from 300 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 16181.70731707 with a remainder of 1.3e-08.
