We're dividing 720662 by 85 
The aim is to understand the frequency of 85 in 720662.

Advancing to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 85

Advancing to step 2:
85 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 85

Going ahead to step 3:
When dividing 720 by 85, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 40 after subtracting 680 from 720.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 85

Going ahead to step 4:
The number 85 fits into 406 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 66 after subtracting 340 from 406.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 85

On to step 5:
If we divide 666 by 85, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 847.0
If we take 595 away from 666, we end up with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 85

On to step 6:
If we divide 712 by 85, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 8478.0
Deduct 680 from 712 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
85 goes into 320 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 8478.3
Subtracting 255 from 320 leaves us 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.

Moving on to step 8:
If we divide 650 by 85, we get 7 and a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 8478.37
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
85 can be fit into 550 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 8478.376
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 8478.3764
Subtracting 340 from 400 leaves us 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.

Moving on to step 11:
85 goes into 600 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 8478.37647
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 85, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8478.37647
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
If we divide 500 by 85, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8478.3764705
Subtract 425 from 500 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.

Let's proceed to step 14:
When dividing 750 by 85, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8478.37647058
If we take 680 away from 750, 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.

After the division, we end up with 8478.37647058 and a remainder of 7e-08.
