We divide 52751437 by 648
The aim is to understand the frequency of 648 in 52751437.

Advancing 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
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 648

Step 2:
When dividing 52 by 648, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 648

Going ahead to step 3:
If we divide 527 by 648, we get 0 and a remainder of 527.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 527 after subtracting 0 from 527.
Take the next digit (5) from the dividend and append it to 527, then repeat: 5275 / 648

Step 4:
648 goes into 5275 8 times with a remainder of 91.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 5184 from 5275 to get 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 648

Let's proceed to step 5:
If we divide 911 by 648, we get 1 and a remainder of 263.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 648 from 911, we get 263.
Bring next digit (4) of the dividend behind the 263 and repeat the process: 2634 / 648

Going ahead to step 6:
When dividing 2634 by 648, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 814.0
Deduct 2592 from 2634 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 648

Going ahead to step 7:
If we divide 423 by 648, we get 0 and a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 8140.0
Deduct 0 from 423 and we're left with 423.
Append the next digit (7) from the dividend to 423 and continue with: 4237 / 648

Advancing to step 8:
When dividing 4237 by 648, we get 6 with a remainder of 349.
Put 6 as the next digit of the answer. 
Result so far: 81406.0
The remainder is 349 after subtracting 3888 from 4237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 9:
If we divide 3490 by 648, we get 5 and a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 81406.5
If we subtract 3240 from 3490, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
When dividing 2500 by 648, we get 3 with a remainder of 556.
The next digit of our result is 3. 
Result so far: 81406.53
Subtracting 1944 from 2500 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 11:
648 can be fit into 5560 8 times, resulting in a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 81406.538
Deduct 5184 from 5560 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 12:
648 can be fit into 3760 5 times, resulting in a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 81406.5385
Subtract 3240 from 3760 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
648 can be fit into 5200 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 81406.53858
The remainder is 16 after subtracting 5184 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 648, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 81406.53858
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
1600 divided by 648 is 2 with a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 81406.5385802
Subtract 1296 from 1600 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
3040 divided by 648 is 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 81406.53858024
If we subtract 2592 from 3040, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Our division results in 81406.53858024 with a remaining 4.48e-07.
