128361 divided by 85 
The aim is to understand the frequency of 85 in 128361.

Step 1:
85 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 85

Step 2:
When dividing 12 by 85, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 85

Advancing to step 3:
128 divided by 85 is 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 85 away from 128, we end up with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 85

Step 4:
433 divided by 85 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 8 after subtracting 425 from 433.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 85

On to step 5:
85 goes into 86 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtract 85 from 86 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 85

Advancing to step 6:
85 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 1510.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 85, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1510.1
Deduct 85 from 110 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
When dividing 250 by 85, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 1510.12
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 1510.129
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
85 goes into 350 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1510.1294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 85, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1510.12941
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
When dividing 150 by 85, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1510.129411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 1510.129411, and the remainder is 6.5e-06.
