38673090 ÷ 138 
The aim is to understand the frequency of 138 in 38673090.

Advancing to step 1:
If we divide 3 by 138, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 138

Advancing to step 2:
When dividing 38 by 138, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 138

Step 3:
When dividing 386 by 138, we get 2 with a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 276 from 386 leaves us with 110.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 138

Step 4:
138 goes into 1107 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 1104 away from 1107, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 138

Moving on to step 5:
When dividing 33 by 138, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 280.0
Subtract 0 from 33 to get 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 138

On to step 6:
330 divided by 138 is 2 with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 2802.0
If we subtract 276 from 330, we get 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 138

On to step 7:
The number 138 fits into 549 3 times, leaving a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 28023.0
If we take 414 away from 549, we end up with 135.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 138

Let's proceed to step 8:
If we divide 1350 by 138, we get 9 and a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 280239.0
If we take 1242 away from 1350, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
138 can be fit into 1080 7 times, resulting in a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 280239.7
Subtract 966 from 1080 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
If we divide 1140 by 138, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 280239.78
Subtracting 1104 from 1140 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
The number 138 fits into 360 2 times, leaving a remainder of 84.
The next digit of our result is 2. 
Result so far: 280239.782
Subtracting 276 from 360 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
If we divide 840 by 138, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 280239.7826
Deduct 828 from 840 and we're left 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 13:
120 divided by 138 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 280239.7826
If we take 0 away from 120, we end up 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.

Moving on to step 14:
1200 divided by 138 is 8 with a remainder of 96.
The next digit of our result is 8. 
Result so far: 280239.782608
Subtracting 1104 from 1200 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 15:
138 goes into 960 6 times with a remainder of 132.
The next digit of our result is 6. 
Result so far: 280239.7826086
If we subtract 828 from 960, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 16:
The number 138 fits into 1320 9 times, leaving a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 280239.78260869
If we subtract 1242 from 1320, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 280239.78260869 with a remaining 7.8e-08.
