52058665 ÷ 648 
The aim is to understand the frequency of 648 in 52058665.

Going ahead to step 1:
648 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 648

Going ahead to step 2:
The number 648 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 648

Step 3:
648 can be fit into 520 0 times, resulting in a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 520, we end up with 520.
Take the next digit (5) from the dividend and append it to 520, then repeat: 5205 / 648

Going ahead to step 4:
The number 648 fits into 5205 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 21 after subtracting 5184 from 5205.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 648

Going ahead to step 5:
If we divide 218 by 648, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 218 and we're left with 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 648

Advancing to step 6:
648 can be fit into 2186 3 times, resulting in a remainder of 242.
Record the quotient 3 as the next digit in the result. 
Result so far: 803.0
Subtract 1944 from 2186 to get 242.
Append the next digit (6) from the dividend to 242 and continue with: 2426 / 648

Step 7:
If we divide 2426 by 648, we get 3 and a remainder of 482.
The next digit of our result is 3. 
Result so far: 8033.0
Deduct 1944 from 2426 and we're left with 482.
Grab the next digit (5) from the dividend, add it to 482, then carry on: 4825 / 648

Going ahead to step 8:
The number 648 fits into 4825 7 times, leaving a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 80337.0
If we take 4536 away from 4825, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
2890 divided by 648 is 4 with a remainder of 298.
Write down 4 as next digit of the result. 
Result so far: 80337.4
If we take 2592 away from 2890, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 10:
648 goes into 2980 4 times with a remainder of 388.
The next digit of our result is 4. 
Result so far: 80337.44
If we take 2592 away from 2980, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 80337.44 with a remaining 0.388.
