We divide 137900 by 102
The aim is to understand the frequency of 102 in 137900.

Let's proceed to step 1:
102 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 102

Step 2:
102 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 102

Going ahead to step 3:
The number 102 fits into 137 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 102 from 137 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 102

Going ahead to step 4:
102 goes into 359 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 306 from 359 to get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 102

Moving on to step 5:
When dividing 530 by 102, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 510 from 530 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 102

Let's proceed to step 6:
When dividing 200 by 102, we get 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 1351.0
Subtracting 102 from 200 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 7:
102 can be fit into 980 9 times, resulting in a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 1351.9
If we subtract 918 from 980, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
When dividing 620 by 102, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1351.96
The remainder is 8 after subtracting 612 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
102 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1351.96
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
When dividing 800 by 102, we get 7 with a remainder of 86.
Use 7 as the next digit of our solution. 
Result so far: 1351.9607
If we subtract 714 from 800, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
102 goes into 860 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 1351.96078
Deduct 816 from 860 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 102 fits into 440 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1351.960784
Deduct 408 from 440 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.

Going ahead to step 13:
320 divided by 102 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1351.9607843
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 102 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1351.96078431
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 1351.96078431, with a leftover of 3.8e-08.
