85787085 divided by 138 
The aim is to understand the frequency of 138 in 85787085.

Moving on to step 1:
138 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 138

On to step 2:
When dividing 85 by 138, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 138

On to step 3:
857 divided by 138 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 828 from 857 and we're left with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 138

Going ahead to step 4:
298 divided by 138 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
The remainder is 22 after subtracting 276 from 298.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 138

Moving on to step 5:
When dividing 227 by 138, we get 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 621.0
If we take 138 away from 227, we end up with 89.
Append the next digit (0) from the dividend to 89 and continue with: 890 / 138

Let's proceed to step 6:
If we divide 890 by 138, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 6216.0
Subtract 828 from 890 to get 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 138

Step 7:
The number 138 fits into 628 4 times, leaving a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 62164.0
Deduct 552 from 628 and we're left with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 138

Advancing to step 8:
If we divide 765 by 138, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 621645.0
Subtract 690 from 765 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
138 can be fit into 750 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 621645.5
If we take 690 away from 750, we end up 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.

Step 10:
If we divide 600 by 138, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 621645.54
If we subtract 552 from 600, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 138 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 621645.543
If we subtract 414 from 480, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
If we divide 660 by 138, we get 4 and a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 621645.5434
Deduct 552 from 660 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
When dividing 1080 by 138, we get 7 with a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 621645.54347
If we subtract 966 from 1080, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
If we divide 1140 by 138, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 621645.543478
Subtract 1104 from 1140 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 15:
The number 138 fits into 360 2 times, leaving a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 621645.5434782
Subtracting 276 from 360 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
138 can be fit into 840 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 621645.54347826
The remainder is 12 after subtracting 828 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 621645.54347826 with a remainder of 1.2e-08.
