68083291 ÷ 448 
The aim is to understand the frequency of 448 in 68083291.

Moving on to step 1:
When dividing 6 by 448, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 448

Moving on to step 2:
448 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 448

Moving on to step 3:
When dividing 680 by 448, we get 1 with a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 448 from 680 and we're left with 232.
Bring next digit (8) of the dividend behind the 232 and repeat the process: 2328 / 448

On to step 4:
The number 448 fits into 2328 5 times, leaving a remainder of 88.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2240 away from 2328, we end up with 88.
Take the next digit (3) from the dividend and append it to 88, then repeat: 883 / 448

Advancing to step 5:
When dividing 883 by 448, we get 1 with a remainder of 435.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we subtract 448 from 883, we get 435.
Grab the next digit (2) from the dividend, add it to 435, then carry on: 4352 / 448

Moving on to step 6:
4352 divided by 448 is 9 with a remainder of 320.
Record the quotient 9 as the next digit in the result. 
Result so far: 1519.0
If we take 4032 away from 4352, we end up with 320.
Append the next digit (9) from the dividend to 320 and continue with: 3209 / 448

On to step 7:
3209 divided by 448 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 15197.0
The remainder is 73 after subtracting 3136 from 3209.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 448

Let's proceed to step 8:
If we divide 731 by 448, we get 1 and a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 151971.0
Subtract 448 from 731 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 9:
When dividing 2830 by 448, we get 6 with a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 151971.6
Subtract 2688 from 2830 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
When dividing 1420 by 448, we get 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 151971.63
If we take 1344 away from 1420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
448 goes into 760 1 times with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 151971.631
If we take 448 away from 760, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 12:
448 goes into 3120 6 times with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 151971.6316
If we take 2688 away from 3120, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 13:
448 can be fit into 4320 9 times, resulting in a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 151971.63169
Subtracting 4032 from 4320 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
448 can be fit into 2880 6 times, resulting in a remainder of 192.
The next digit of our result is 6. 
Result so far: 151971.631696
The remainder is 192 after subtracting 2688 from 2880.
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:
When dividing 1920 by 448, we get 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 151971.6316964
The remainder is 128 after subtracting 1792 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
448 can be fit into 1280 2 times, resulting in a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 151971.63169642
Subtracting 896 from 1280 leaves us 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.

After the division, we end up with 151971.63169642 and a remainder of 3.84e-07.
