We divide 644494 by 85
We want to divide 644494 by 85.

Step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 85

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
Subtract 0 from 64 to get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 85

Step 3:
The number 85 fits into 644 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 595 from 644 leaves us with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 85

Let's proceed to step 4:
If we divide 494 by 85, we get 5 and a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 425 from 494 leaves us with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 85

Let's proceed to step 5:
85 goes into 699 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 758.0
If we take 680 away from 699, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 85

Going ahead to step 6:
If we divide 194 by 85, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7582.0
If we subtract 170 from 194, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
85 goes into 240 2 times with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 7582.2
If we subtract 170 from 240, we 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 8:
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: 7582.28
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 85, we get 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 7582.282
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 85, we get 3 and a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 7582.2823
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
450 divided by 85 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7582.28235
Deduct 425 from 450 and we're left 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.

Advancing to step 12:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 7582.282352
If we take 170 away from 250, we end up 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.

On to step 13:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 7582.2823529
Subtracting 765 from 800 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
350 divided by 85 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 7582.28235294
If we take 340 away from 350, we end up 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.

The final result is 7582.28235294 with a remainder of 1e-08.
