5599189 ÷ 138 
The aim is to understand the frequency of 138 in 5599189.

Let's proceed to step 1:
138 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 138

On to step 2:
138 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 138

Moving on to step 3:
138 goes into 559 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 552 from 559 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 138

Let's proceed to step 4:
The number 138 fits into 79 0 times, leaving a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 79 leaves us with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 138

Step 5:
791 divided by 138 is 5 with a remainder of 101.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Subtract 690 from 791 to get 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 138

On to step 6:
When dividing 1018 by 138, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 4057.0
Deduct 966 from 1018 and we're left with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 138

On to step 7:
When dividing 529 by 138, we get 3 with a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 40573.0
If we subtract 414 from 529, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 8:
138 can be fit into 1150 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 40573.8
Deduct 1104 from 1150 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
The number 138 fits into 460 3 times, leaving a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 40573.83
If we take 414 away from 460, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
The number 138 fits into 460 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 40573.833
The remainder is 46 after subtracting 414 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 40573.833 with a remaining 0.0046.
