68599478 ÷ 448 
The aim is to understand the frequency of 448 in 68599478.

On to step 1:
448 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 448

On to step 2:
448 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 448

Step 3:
The number 448 fits into 685 1 times, leaving a remainder of 237.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 237 after subtracting 448 from 685.
Fetch the next digit (9) from the dividend, attach it to 237 and continue: 2379 / 448

Moving on to step 4:
448 can be fit into 2379 5 times, resulting in a remainder of 139.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2240 from 2379 and we're left with 139.
Fetch the next digit (9) from the dividend, attach it to 139 and continue: 1399 / 448

Advancing to step 5:
The number 448 fits into 1399 3 times, leaving a remainder of 55.
The next digit of our result is 3. 
Result so far: 153.0
If we take 1344 away from 1399, we end up with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 448

On to step 6:
554 divided by 448 is 1 with a remainder of 106.
Record the quotient 1 as the next digit in the result. 
Result so far: 1531.0
If we take 448 away from 554, we end up with 106.
Take the next digit (7) from the dividend and append it to 106, then repeat: 1067 / 448

Moving on to step 7:
1067 divided by 448 is 2 with a remainder of 171.
The number 2 becomes the next digit in our result. 
Result so far: 15312.0
If we take 896 away from 1067, we end up with 171.
Grab the next digit (8) from the dividend, add it to 171, then carry on: 1718 / 448

Let's proceed to step 8:
1718 divided by 448 is 3 with a remainder of 374.
The next digit of our result is 3. 
Result so far: 153123.0
If we take 1344 away from 1718, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 9:
The number 448 fits into 3740 8 times, leaving a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 153123.8
The remainder is 156 after subtracting 3584 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
1560 divided by 448 is 3 with a remainder of 216.
The next digit of our result is 3. 
Result so far: 153123.83
Deduct 1344 from 1560 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 11:
When dividing 2160 by 448, we get 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 153123.834
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.

Step 12:
448 can be fit into 3680 8 times, resulting in a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 153123.8348
Subtracting 3584 from 3680 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
When dividing 960 by 448, we get 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 153123.83482
If we take 896 away from 960, we end up 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 14:
The number 448 fits into 640 1 times, leaving a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 153123.834821
The remainder is 192 after subtracting 448 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
The number 448 fits into 1920 4 times, leaving a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 153123.8348214
Deduct 1792 from 1920 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
When dividing 1280 by 448, we get 2 with a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 153123.83482142
Deduct 896 from 1280 and we're left 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.

The quotient of the division is 153123.83482142, and the remainder is 3.84e-07.
