We're dividing 64911326 by 138 
The aim is to understand the frequency of 138 in 64911326.

Advancing to step 1:
If we divide 6 by 138, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 138

On to step 2:
The number 138 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 138

Step 3:
If we divide 649 by 138, we get 4 and a remainder of 97.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 97 after subtracting 552 from 649.
Take the next digit (1) from the dividend and append it to 97, then repeat: 971 / 138

Going ahead to step 4:
If we divide 971 by 138, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 966 from 971 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 138

Moving on to step 5:
If we divide 51 by 138, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
If we subtract 0 from 51, we get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 138

Advancing to step 6:
138 goes into 513 3 times with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 4703.0
Deduct 414 from 513 and we're left with 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 138

Moving on to step 7:
When dividing 992 by 138, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 47037.0
Subtract 966 from 992 to get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 138

Let's proceed to step 8:
When dividing 266 by 138, we get 1 with a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 470371.0
Subtract 138 from 266 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
138 can be fit into 1280 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 470371.9
If we subtract 1242 from 1280, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
If we divide 380 by 138, we get 2 and a remainder of 104.
The next digit of our result is 2. 
Result so far: 470371.92
Subtract 276 from 380 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.

Let's proceed to step 11:
138 goes into 1040 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 470371.927
Subtracting 966 from 1040 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
The number 138 fits into 740 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 470371.9275
Subtracting 690 from 740 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
The number 138 fits into 500 3 times, leaving a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 470371.92753
If we take 414 away from 500, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 14:
If we divide 860 by 138, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 470371.927536
Deduct 828 from 860 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
The number 138 fits into 320 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 470371.9275362
Subtract 276 from 320 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 16:
138 goes into 440 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 470371.92753623
Subtract 414 from 440 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 470371.92753623 with a remaining 2.6e-08.
