We divide 667985 by 85
The aim is to understand the frequency of 85 in 667985.

Moving on to step 1:
6 divided by 85 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 85

On to step 2:
When dividing 66 by 85, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 85

Step 3:
When dividing 667 by 85, we get 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 595 from 667 and we're left with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 85

Let's proceed to step 4:
If we divide 729 by 85, we get 8 and a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 680 from 729 and we're left with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 85

Step 5:
498 divided by 85 is 5 with a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
Subtract 425 from 498 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 85

On to step 6:
If we divide 735 by 85, we get 8 and a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 7858.0
Subtract 680 from 735 to 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.

Moving on to step 7:
If we divide 550 by 85, we get 6 and a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 7858.6
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 85, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 7858.64
Deduct 340 from 400 and we're left 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.

Let's proceed to step 9:
When dividing 600 by 85, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 7858.647
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7858.647
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7858.64705
If we take 425 away from 500, we end up with 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 12:
If we divide 750 by 85, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 7858.647058
Subtracting 680 from 750 leaves us 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.

Let's proceed to step 13:
700 divided by 85 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 7858.6470588
Subtracting 680 from 700 leaves us 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.

The final outcome is 7858.6470588, with a leftover of 2e-07.
