We divide 38449211 by 648
The aim is to understand the frequency of 648 in 38449211.

Step 1:
648 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 648

On to step 2:
38 divided by 648 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 648

Going ahead to step 3:
When dividing 384 by 648, we get 0 with a remainder of 384.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 384 to get 384.
Grab the next digit (4) from the dividend, add it to 384, then carry on: 3844 / 648

Moving on to step 4:
The number 648 fits into 3844 5 times, leaving a remainder of 604.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3240 from 3844 and we're left with 604.
Include the next digit (9) from the dividend after 604, then repeat: 6049 / 648

Let's proceed to step 5:
The number 648 fits into 6049 9 times, leaving a remainder of 217.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 5832 from 6049 leaves us with 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 648

Step 6:
When dividing 2172 by 648, we get 3 with a remainder of 228.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
The remainder is 228 after subtracting 1944 from 2172.
Fetch the next digit (1) from the dividend, attach it to 228 and continue: 2281 / 648

Advancing to step 7:
2281 divided by 648 is 3 with a remainder of 337.
Put 3 as the next digit of the answer. 
Result so far: 5933.0
Subtracting 1944 from 2281 leaves us with 337.
Include the next digit (1) from the dividend after 337, then repeat: 3371 / 648

Advancing to step 8:
When dividing 3371 by 648, we get 5 with a remainder of 131.
The next digit of our result is 5. 
Result so far: 59335.0
The remainder is 131 after subtracting 3240 from 3371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 9:
If we divide 1310 by 648, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 59335.2
Deduct 1296 from 1310 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
140 divided by 648 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 59335.2
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
If we divide 1400 by 648, we get 2 and a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 59335.202
Subtract 1296 from 1400 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 12:
When dividing 1040 by 648, we get 1 with a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 59335.2021
Subtracting 648 from 1040 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 13:
If we divide 3920 by 648, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 59335.20216
The remainder is 32 after subtracting 3888 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
648 can be fit into 320 0 times, resulting in a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 59335.20216
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
648 goes into 3200 4 times with a remainder of 608.
The number 4 becomes the next digit in our result. 
Result so far: 59335.2021604
If we subtract 2592 from 3200, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 16:
6080 divided by 648 is 9 with a remainder of 248.
Put 9 as the next digit of the answer. 
Result so far: 59335.20216049
If we subtract 5832 from 6080, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 59335.20216049 with a remaining 2.48e-07.
