We look at the division of 73253582 by 138 
The aim is to understand the frequency of 138 in 73253582.

Step 1:
138 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 138

On to step 2:
73 divided by 138 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 138

Advancing to step 3:
When dividing 732 by 138, we get 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 690 from 732 to get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 138

Step 4:
The number 138 fits into 425 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 414 away from 425, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 138

Let's proceed to step 5:
113 divided by 138 is 0 with a remainder of 113.
Write down 0 as next digit of the result. 
Result so far: 530.0
If we take 0 away from 113, we end up with 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 138

Going ahead to step 6:
If we divide 1135 by 138, we get 8 and a remainder of 31.
The next digit of our result is 8. 
Result so far: 5308.0
The remainder is 31 after subtracting 1104 from 1135.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 138

On to step 7:
138 goes into 318 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 53082.0
If we take 276 away from 318, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 138

Advancing to step 8:
138 can be fit into 422 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 530823.0
Subtract 414 from 422 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 138, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 530823.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
138 can be fit into 800 5 times, resulting in a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 530823.05
If we subtract 690 from 800, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
1100 divided by 138 is 7 with a remainder of 134.
The next digit of our result is 7. 
Result so far: 530823.057
Subtract 966 from 1100 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 12:
138 goes into 1340 9 times with a remainder of 98.
The next digit of our result is 9. 
Result so far: 530823.0579
The remainder is 98 after subtracting 1242 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
The number 138 fits into 980 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 530823.05797
If we take 966 away from 980, we end up 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 14:
138 goes into 140 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 530823.057971
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
138 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 530823.057971
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
When dividing 200 by 138, we get 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 530823.05797101
Deduct 138 from 200 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 530823.05797101 and a remainder of 6.2e-08.
