We look at the division of 77994587 by 449 
The aim is to understand the frequency of 449 in 77994587.

Going ahead to step 1:
The number 449 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 449

Moving on to step 2:
77 divided by 449 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 449

Going ahead to step 3:
The number 449 fits into 779 1 times, leaving a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 449 away from 779, we end up with 330.
Include the next digit (9) from the dividend after 330, then repeat: 3309 / 449

Step 4:
If we divide 3309 by 449, we get 7 and a remainder of 166.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 166 after subtracting 3143 from 3309.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 449

Moving on to step 5:
If we divide 1664 by 449, we get 3 and a remainder of 317.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Subtract 1347 from 1664 to get 317.
Grab the next digit (5) from the dividend, add it to 317, then carry on: 3175 / 449

Let's proceed to step 6:
If we divide 3175 by 449, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1737.0
Subtracting 3143 from 3175 leaves us with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 449

Step 7:
The number 449 fits into 328 0 times, leaving a remainder of 328.
Write down 0 as next digit of the result. 
Result so far: 17370.0
Subtracting 0 from 328 leaves us with 328.
Take the next digit (7) from the dividend and append it to 328, then repeat: 3287 / 449

Let's proceed to step 8:
3287 divided by 449 is 7 with a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 173707.0
If we subtract 3143 from 3287, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 9:
If we divide 1440 by 449, we get 3 and a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 173707.3
Subtract 1347 from 1440 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 10:
449 can be fit into 930 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 173707.32
Subtracting 898 from 930 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
449 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 173707.32
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 449, we get 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 173707.3207
Subtracting 3143 from 3200 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
When dividing 570 by 449, we get 1 with a remainder of 121.
Write down 1 as next digit of the result. 
Result so far: 173707.32071
If we subtract 449 from 570, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 14:
If we divide 1210 by 449, we get 2 and a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 173707.320712
The remainder is 312 after subtracting 898 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 15:
3120 divided by 449 is 6 with a remainder of 426.
Put 6 as the next digit of the answer. 
Result so far: 173707.3207126
The remainder is 426 after subtracting 2694 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 16:
449 can be fit into 4260 9 times, resulting in a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 173707.32071269
If we subtract 4041 from 4260, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Our division results in 173707.32071269 with a remaining 2.19e-07.
