We look at the division of 93850041 by 648 
The aim is to understand the frequency of 648 in 93850041.

Advancing to step 1:
648 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 648

Let's proceed to step 2:
When dividing 93 by 648, we get 0 with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 648

Step 3:
If we divide 938 by 648, we get 1 and a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 648 from 938 to get 290.
Take the next digit (5) from the dividend and append it to 290, then repeat: 2905 / 648

Let's proceed to step 4:
648 goes into 2905 4 times with a remainder of 313.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2592 from 2905, we get 313.
Grab the next digit (0) from the dividend, add it to 313, then carry on: 3130 / 648

On to step 5:
When dividing 3130 by 648, we get 4 with a remainder of 538.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Deduct 2592 from 3130 and we're left with 538.
Fetch the next digit (0) from the dividend, attach it to 538 and continue: 5380 / 648

Going ahead to step 6:
648 can be fit into 5380 8 times, resulting in a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 1448.0
The remainder is 196 after subtracting 5184 from 5380.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 648

Moving on to step 7:
If we divide 1964 by 648, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 14483.0
Subtracting 1944 from 1964 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 648

Moving on to step 8:
648 goes into 201 0 times with a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 144830.0
If we subtract 0 from 201, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
If we divide 2010 by 648, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 144830.3
Deduct 1944 from 2010 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
If we divide 660 by 648, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 144830.31
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
648 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 144830.31
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
If we divide 1200 by 648, we get 1 and a remainder of 552.
Put 1 as the next digit of the answer. 
Result so far: 144830.3101
Subtracting 648 from 1200 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 13:
5520 divided by 648 is 8 with a remainder of 336.
The next digit of our result is 8. 
Result so far: 144830.31018
If we take 5184 away from 5520, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 14:
If we divide 3360 by 648, we get 5 and a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 144830.310185
Deduct 3240 from 3360 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
1200 divided by 648 is 1 with a remainder of 552.
Record the quotient 1 as the next digit in the result. 
Result so far: 144830.3101851
Subtract 648 from 1200 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 16:
648 goes into 5520 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 144830.31018518
Subtract 5184 from 5520 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 144830.31018518 with a remaining 3.36e-07.
