55525656 divided by 138 
The aim is to understand the frequency of 138 in 55525656.

Let's proceed to step 1:
When dividing 5 by 138, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 138

Advancing to step 2:
When dividing 55 by 138, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 138

Advancing to step 3:
When dividing 555 by 138, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 552 from 555 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 138

Going ahead to step 4:
When dividing 32 by 138, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 32, we end up with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 138

Going ahead to step 5:
138 can be fit into 325 2 times, resulting in a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 402.0
Subtracting 276 from 325 leaves us with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 138

Moving on to step 6:
If we divide 496 by 138, we get 3 and a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 4023.0
Subtracting 414 from 496 leaves us with 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 138

Step 7:
825 divided by 138 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 40235.0
If we subtract 690 from 825, we get 135.
Grab the next digit (6) from the dividend, add it to 135, then carry on: 1356 / 138

Let's proceed to step 8:
1356 divided by 138 is 9 with a remainder of 114.
Write down 9 as next digit of the result. 
Result so far: 402359.0
The remainder is 114 after subtracting 1242 from 1356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
1140 divided by 138 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 402359.8
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.

Advancing to step 10:
360 divided by 138 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 402359.82
If we subtract 276 from 360, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
138 can be fit into 840 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 402359.826
If we take 828 away from 840, we end up 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.

Moving on to step 12:
138 goes into 120 0 times with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 402359.826
If we subtract 0 from 120, we 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.

Going ahead to step 13:
138 can be fit into 1200 8 times, resulting in a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 402359.82608
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.

On to step 14:
138 can be fit into 960 6 times, resulting in a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 402359.826086
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 15:
The number 138 fits into 1320 9 times, leaving a remainder of 78.
The next digit of our result is 9. 
Result so far: 402359.8260869
Subtract 1242 from 1320 to 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.

Advancing to step 16:
138 goes into 780 5 times with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 402359.82608695
If we take 690 away from 780, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 402359.82608695 and a remainder of 9e-08.
