Let's divide 17255274 by 138
The aim is to understand the frequency of 138 in 17255274.

Going ahead to step 1:
When dividing 1 by 138, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 138

Let's proceed to step 2:
If we divide 17 by 138, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 138

Advancing to step 3:
The number 138 fits into 172 1 times, leaving a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 138 from 172 and we're left with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 138

Advancing to step 4:
345 divided by 138 is 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 276 away from 345, we end up with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 138

Advancing to step 5:
When dividing 695 by 138, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 5 after subtracting 690 from 695.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 138

Advancing to step 6:
If we divide 52 by 138, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 1250.0
The remainder is 52 after subtracting 0 from 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 138

Step 7:
The number 138 fits into 527 3 times, leaving a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 12503.0
The remainder is 113 after subtracting 414 from 527.
Fetch the next digit (4) from the dividend, attach it to 113 and continue: 1134 / 138

Let's proceed to step 8:
138 can be fit into 1134 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 125038.0
Subtracting 1104 from 1134 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
138 goes into 300 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 125038.2
Subtract 276 from 300 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
138 can be fit into 240 1 times, resulting in a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 125038.21
If we take 138 away from 240, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
If we divide 1020 by 138, we get 7 and a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 125038.217
Subtract 966 from 1020 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
When dividing 540 by 138, we get 3 with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 125038.2173
If we subtract 414 from 540, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 13:
138 can be fit into 1260 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 125038.21739
The remainder is 18 after subtracting 1242 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
If we divide 180 by 138, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 125038.217391
If we subtract 138 from 180, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 15:
138 can be fit into 420 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 125038.2173913
Subtract 414 from 420 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 16:
The number 138 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 125038.2173913
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 125038.2173913 and a remainder of 6e-08.
