We divide 15540 by 85
The aim is to understand the frequency of 85 in 15540.

Let's proceed to step 1:
When dividing 1 by 85, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 85

Advancing to step 2:
The number 85 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 85

On to step 3:
If we divide 155 by 85, we get 1 and a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 85 away from 155, we end up with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 85

Let's proceed to step 4:
The number 85 fits into 704 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 680 from 704 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 85

Moving on to step 5:
If we divide 240 by 85, we get 2 and a remainder of 70.
The next digit of our result is 2. 
Result so far: 182.0
If we take 170 away from 240, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
If we divide 700 by 85, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 182.8
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
85 goes into 200 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 182.82
Deduct 170 from 200 and we're left 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.

Moving on to step 8:
If we divide 300 by 85, we get 3 and a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 182.823
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 85, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 182.8235
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
If we divide 250 by 85, we get 2 and a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 182.82352
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
The number 85 fits into 800 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 182.823529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
When dividing 350 by 85, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 182.8235294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 85, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 182.82352941
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 182.82352941, and the remainder is 1.5e-08.
