Let's divide 646374 by 85
We're looking to find how many times 85 goes into 646374.

Going ahead 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 85

Moving on to step 2:
85 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 85

Advancing to step 3:
85 can be fit into 646 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 595 from 646 to get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 85

Moving on to step 4:
85 can be fit into 513 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 510 from 513 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 85

On to step 5:
85 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 760.0
If we take 0 away from 37, we end up with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 85

Going ahead to step 6:
When dividing 374 by 85, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 7604.0
The remainder is 34 after subtracting 340 from 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
The number 85 fits into 340 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 7604.4
Subtract 340 from 340 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 85, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7604.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 85 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7604.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 7604.4 with a balance of 0.0.
