We divide 61102599 by 449
The aim is to understand the frequency of 449 in 61102599.

Moving on to step 1:
If we divide 6 by 449, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 449

Advancing to step 2:
When dividing 61 by 449, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 449

Let's proceed to step 3:
If we divide 611 by 449, we get 1 and a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 449 from 611 leaves us with 162.
Take the next digit (0) from the dividend and append it to 162, then repeat: 1620 / 449

Going ahead to step 4:
When dividing 1620 by 449, we get 3 with a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 273 after subtracting 1347 from 1620.
Grab the next digit (2) from the dividend, add it to 273, then carry on: 2732 / 449

On to step 5:
449 goes into 2732 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
The remainder is 38 after subtracting 2694 from 2732.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 449

Step 6:
385 divided by 449 is 0 with a remainder of 385.
The next digit of our result is 0. 
Result so far: 1360.0
Subtracting 0 from 385 leaves us with 385.
Grab the next digit (9) from the dividend, add it to 385, then carry on: 3859 / 449

Advancing to step 7:
3859 divided by 449 is 8 with a remainder of 267.
The next digit of our result is 8. 
Result so far: 13608.0
The remainder is 267 after subtracting 3592 from 3859.
Take the next digit (9) from the dividend and append it to 267, then repeat: 2679 / 449

Advancing to step 8:
The number 449 fits into 2679 5 times, leaving a remainder of 434.
The number 5 becomes the next digit in our result. 
Result so far: 136085.0
If we take 2245 away from 2679, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 9:
When dividing 4340 by 449, we get 9 with a remainder of 299.
The next digit of our result is 9. 
Result so far: 136085.9
The remainder is 299 after subtracting 4041 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 10:
2990 divided by 449 is 6 with a remainder of 296.
The next digit of our result is 6. 
Result so far: 136085.96
If we take 2694 away from 2990, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
The number 449 fits into 2960 6 times, leaving a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 136085.966
Subtract 2694 from 2960 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final outcome is 136085.966, with a leftover of 0.0266.
