We look at the division of 61207 by 85 
The aim is to understand the frequency of 85 in 61207.

Let's proceed to step 1:
When dividing 6 by 85, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 85

On to step 2:
If we divide 61 by 85, we get 0 and a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 85

On to step 3:
612 divided by 85 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 17 after subtracting 595 from 612.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 85

On to step 4:
When dividing 170 by 85, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 170 from 170 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 85

Step 5:
85 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 720.0
The remainder is 7 after subtracting 0 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
85 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 720.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
85 goes into 700 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 720.08
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.

Advancing to step 8:
When dividing 200 by 85, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 720.082
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 85, we get 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 720.0823
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
When dividing 450 by 85, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 720.08235
Subtracting 425 from 450 leaves us 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.

Step 11:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 720.082352
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.

Let's proceed to step 12:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 720.0823529
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.

Going ahead to step 13:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 720.08235294
Deduct 340 from 350 and we're left 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.

After the division, we end up with 720.08235294 and a remainder of 1e-08.
