We look at the division of 12922517 by 448 
The aim is to understand the frequency of 448 in 12922517.

Step 1:
1 divided by 448 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 448

Advancing to step 2:
The number 448 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 448

Moving on to step 3:
When dividing 129 by 448, we get 0 with a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Fetch the next digit (2) from the dividend, attach it to 129 and continue: 1292 / 448

Step 4:
1292 divided by 448 is 2 with a remainder of 396.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 896 from 1292, we get 396.
Bring next digit (2) of the dividend behind the 396 and repeat the process: 3962 / 448

Going ahead to step 5:
If we divide 3962 by 448, we get 8 and a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 3584 from 3962 to get 378.
Bring next digit (5) of the dividend behind the 378 and repeat the process: 3785 / 448

Advancing to step 6:
3785 divided by 448 is 8 with a remainder of 201.
Use 8 as the next digit of our solution. 
Result so far: 288.0
If we take 3584 away from 3785, we end up with 201.
Grab the next digit (1) from the dividend, add it to 201, then carry on: 2011 / 448

Going ahead to step 7:
If we divide 2011 by 448, we get 4 and a remainder of 219.
Put 4 as the next digit of the answer. 
Result so far: 2884.0
If we take 1792 away from 2011, we end up with 219.
Fetch the next digit (7) from the dividend, attach it to 219 and continue: 2197 / 448

Step 8:
2197 divided by 448 is 4 with a remainder of 405.
Put 4 as the next digit of the answer. 
Result so far: 28844.0
If we subtract 1792 from 2197, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 9:
If we divide 4050 by 448, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 28844.9
If we take 4032 away from 4050, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 448, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 28844.9
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
If we divide 1800 by 448, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 28844.904
Deduct 1792 from 1800 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 12:
If we divide 80 by 448, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 28844.904
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
448 goes into 800 1 times with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 28844.90401
Subtract 448 from 800 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
If we divide 3520 by 448, we get 7 and a remainder of 384.
The number 7 becomes the next digit in our result. 
Result so far: 28844.904017
If we take 3136 away from 3520, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 15:
If we divide 3840 by 448, we get 8 and a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 28844.9040178
Deduct 3584 from 3840 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 16:
When dividing 2560 by 448, we get 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 28844.90401785
Deduct 2240 from 2560 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.

The quotient of the division is 28844.90401785, and the remainder is 3.2e-07.
