640956 ÷ 85 
We want to divide 640956 by 85.

Advancing to step 1:
6 divided by 85 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 85

Step 2:
85 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 85

On to step 3:
640 divided by 85 is 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 45 after subtracting 595 from 640.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 85

On to step 4:
If we divide 459 by 85, we get 5 and a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 425 from 459 leaves us with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 85

Moving on to step 5:
85 goes into 345 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 754.0
The remainder is 5 after subtracting 340 from 345.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 85

Going ahead to step 6:
When dividing 56 by 85, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 7540.0
Subtract 0 from 56 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
85 goes into 560 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 7540.6
If we take 510 away from 560, we end up 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.

Going ahead to step 8:
If we divide 500 by 85, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 7540.65
Deduct 425 from 500 and we're left 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 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 7540.658
The remainder is 70 after subtracting 680 from 750.
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.
Write down 8 as next digit of the result. 
Result so far: 7540.6588
The remainder is 20 after subtracting 680 from 700.
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 result is 7540.6588 with a remainder of 0.0002.
