We look at the division of 13146875 by 137 
The aim is to understand the frequency of 137 in 13146875.

Moving on to step 1:
137 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 137

Step 2:
137 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 137

On to step 3:
The number 137 fits into 131 0 times, leaving a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Fetch the next digit (4) from the dividend, attach it to 131 and continue: 1314 / 137

Moving on to step 4:
If we divide 1314 by 137, we get 9 and a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 81 after subtracting 1233 from 1314.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 137

Going ahead to step 5:
137 goes into 816 5 times with a remainder of 131.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 131 after subtracting 685 from 816.
Bring next digit (8) of the dividend behind the 131 and repeat the process: 1318 / 137

Advancing to step 6:
137 can be fit into 1318 9 times, resulting in a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 959.0
Subtracting 1233 from 1318 leaves us with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 137

Moving on to step 7:
The number 137 fits into 857 6 times, leaving a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 9596.0
Subtracting 822 from 857 leaves us with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 137

On to step 8:
137 can be fit into 355 2 times, resulting in a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 95962.0
Subtracting 274 from 355 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
The number 137 fits into 810 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 95962.5
Subtracting 685 from 810 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
When dividing 1250 by 137, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 95962.59
If we subtract 1233 from 1250, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
When dividing 170 by 137, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 95962.591
Subtracting 137 from 170 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
137 goes into 330 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 95962.5912
If we take 274 away from 330, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
137 goes into 560 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 95962.59124
Deduct 548 from 560 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.

Step 14:
137 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 95962.59124
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
If we divide 1200 by 137, we get 8 and a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 95962.5912408
If we subtract 1096 from 1200, we 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.

On to step 16:
The number 137 fits into 1040 7 times, leaving a remainder of 81.
The next digit of our result is 7. 
Result so far: 95962.59124087
If we take 959 away from 1040, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 95962.59124087, with a leftover of 8.1e-08.
