64254780 divided by 448 
The aim is to understand the frequency of 448 in 64254780.

Let's proceed to step 1:
448 goes into 6 0 times with 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 (4) from the dividend to 6 and continue with: 64 / 448

Step 2:
448 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 448

Moving on to step 3:
The number 448 fits into 642 1 times, leaving a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 448 from 642 to get 194.
Fetch the next digit (5) from the dividend, attach it to 194 and continue: 1945 / 448

Let's proceed to step 4:
If we divide 1945 by 448, we get 4 and a remainder of 153.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1792 from 1945 to get 153.
Bring next digit (4) of the dividend behind the 153 and repeat the process: 1534 / 448

Let's proceed to step 5:
448 goes into 1534 3 times with a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 143.0
Deduct 1344 from 1534 and we're left with 190.
Fetch the next digit (7) from the dividend, attach it to 190 and continue: 1907 / 448

Advancing to step 6:
The number 448 fits into 1907 4 times, leaving a remainder of 115.
Put 4 as the next digit of the answer. 
Result so far: 1434.0
The remainder is 115 after subtracting 1792 from 1907.
Grab the next digit (8) from the dividend, add it to 115, then carry on: 1158 / 448

Let's proceed to step 7:
When dividing 1158 by 448, we get 2 with a remainder of 262.
Write down 2 as next digit of the result. 
Result so far: 14342.0
The remainder is 262 after subtracting 896 from 1158.
Include the next digit (0) from the dividend after 262, then repeat: 2620 / 448

Going ahead to step 8:
2620 divided by 448 is 5 with a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 143425.0
Deduct 2240 from 2620 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
448 can be fit into 3800 8 times, resulting in a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 143425.8
If we subtract 3584 from 3800, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
448 can be fit into 2160 4 times, resulting in a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 143425.84
Subtracting 1792 from 2160 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
3680 divided by 448 is 8 with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 143425.848
Subtract 3584 from 3680 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 12:
When dividing 960 by 448, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 143425.8482
Subtracting 896 from 960 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
When dividing 640 by 448, we get 1 with a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 143425.84821
If we subtract 448 from 640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 14:
If we divide 1920 by 448, we get 4 and a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 143425.848214
If we subtract 1792 from 1920, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
When dividing 1280 by 448, we get 2 with a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 143425.8482142
Subtract 896 from 1280 to get 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 16:
3840 divided by 448 is 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 143425.84821428
The remainder is 256 after subtracting 3584 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 143425.84821428 and a remainder of 2.56e-07.
