We divide 42607664 by 138
The aim is to understand the frequency of 138 in 42607664.

Going ahead to step 1:
If we divide 4 by 138, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 138

On to step 2:
The number 138 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 138

Moving on to step 3:
138 can be fit into 426 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 12 after subtracting 414 from 426.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 138

Let's proceed to step 4:
When dividing 120 by 138, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 120 to get 120.
Fetch the next digit (7) from the dividend, attach it to 120 and continue: 1207 / 138

On to step 5:
138 can be fit into 1207 8 times, resulting in a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
Deduct 1104 from 1207 and we're left with 103.
Fetch the next digit (6) from the dividend, attach it to 103 and continue: 1036 / 138

Going ahead to step 6:
1036 divided by 138 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 3087.0
Subtracting 966 from 1036 leaves us with 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 138

Moving on to step 7:
When dividing 706 by 138, we get 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 30875.0
If we subtract 690 from 706, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 138

Moving on to step 8:
If we divide 164 by 138, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 308751.0
Subtracting 138 from 164 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
138 goes into 260 1 times with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 308751.1
Subtract 138 from 260 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
If we divide 1220 by 138, we get 8 and a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 308751.18
The remainder is 116 after subtracting 1104 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
138 goes into 1160 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 308751.188
Subtracting 1104 from 1160 leaves us 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.

The final outcome is 308751.188, with a leftover of 0.0056.
