We're dividing 645325 by 85 
Let's see how many times 85 fits into 645325.

Step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 85

Moving on to step 2:
If we divide 64 by 85, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 85

Going ahead to step 3:
85 can be fit into 645 7 times, resulting in a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 50 after subtracting 595 from 645.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 85

Going ahead to step 4:
503 divided by 85 is 5 with a remainder of 78.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 425 from 503 and we're left with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 85

Let's proceed to step 5:
85 goes into 782 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 759.0
Deduct 765 from 782 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 85

Let's proceed to step 6:
85 can be fit into 175 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 7592.0
Subtract 170 from 175 to 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.

Step 7:
When dividing 50 by 85, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7592.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
When dividing 500 by 85, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 7592.05
The remainder is 75 after subtracting 425 from 500.
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 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 7592.058
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.

Advancing to step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 7592.0588
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 7592.0588, with a leftover of 0.0002.
