Let's divide 684643 by 85
We want to divide 684643 by 85.

Let's proceed to step 1:
6 divided by 85 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 85

Step 2:
When dividing 68 by 85, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 85

Let's proceed to step 3:
684 divided by 85 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 680 from 684 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 85

Let's proceed to step 4:
When dividing 46 by 85, we get 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 46, we get 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 85

Going ahead to step 5:
The number 85 fits into 464 5 times, leaving a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
Subtracting 425 from 464 leaves us with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 85

Going ahead to step 6:
393 divided by 85 is 4 with a remainder of 53.
The next digit of our result is 4. 
Result so far: 8054.0
If we subtract 340 from 393, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
85 can be fit into 530 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 8054.6
Deduct 510 from 530 and we're left 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.

Let's proceed to step 8:
The number 85 fits into 200 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 8054.62
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 85, we get 3 and a remainder of 45.
The next digit of our result is 3. 
Result so far: 8054.623
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
450 divided by 85 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8054.6235
Subtracting 425 from 450 leaves us 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.

Going ahead to step 11:
If we divide 250 by 85, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 8054.62352
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
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: 8054.623529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
350 divided by 85 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 8054.6235294
Deduct 340 from 350 and we're left 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.

Let's proceed to step 14:
When dividing 100 by 85, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 8054.62352941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 8054.62352941, and the remainder is 1.5e-08.
