We look at the division of 60041903 by 449 
The aim is to understand the frequency of 449 in 60041903.

Going ahead to step 1:
The number 449 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 449

On to step 2:
The number 449 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 449

Moving on to step 3:
449 goes into 600 1 times with a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 449 from 600 and we're left with 151.
Bring next digit (4) of the dividend behind the 151 and repeat the process: 1514 / 449

On to step 4:
The number 449 fits into 1514 3 times, leaving a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1347 from 1514 to get 167.
Fetch the next digit (1) from the dividend, attach it to 167 and continue: 1671 / 449

Going ahead to step 5:
449 goes into 1671 3 times with a remainder of 324.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we subtract 1347 from 1671, we get 324.
Bring next digit (9) of the dividend behind the 324 and repeat the process: 3249 / 449

On to step 6:
If we divide 3249 by 449, we get 7 and a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
If we subtract 3143 from 3249, we get 106.
Include the next digit (0) from the dividend after 106, then repeat: 1060 / 449

On to step 7:
449 goes into 1060 2 times with a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 13372.0
If we subtract 898 from 1060, we get 162.
Take the next digit (3) from the dividend and append it to 162, then repeat: 1623 / 449

Let's proceed to step 8:
When dividing 1623 by 449, we get 3 with a remainder of 276.
Record the quotient 3 as the next digit in the result. 
Result so far: 133723.0
Subtract 1347 from 1623 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 9:
If we divide 2760 by 449, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 133723.6
The remainder is 66 after subtracting 2694 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
The number 449 fits into 660 1 times, leaving a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 133723.61
Deduct 449 from 660 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 11:
449 can be fit into 2110 4 times, resulting in a remainder of 314.
The next digit of our result is 4. 
Result so far: 133723.614
Subtracting 1796 from 2110 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
If we divide 3140 by 449, we get 6 and a remainder of 446.
Use 6 as the next digit of our solution. 
Result so far: 133723.6146
The remainder is 446 after subtracting 2694 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 13:
If we divide 4460 by 449, we get 9 and a remainder of 419.
The number 9 becomes the next digit in our result. 
Result so far: 133723.61469
If we take 4041 away from 4460, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 14:
When dividing 4190 by 449, we get 9 with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 133723.614699
Deduct 4041 from 4190 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 133723.614699 with a remainder of 1.49e-05.
