Let's divide 661408 by 85
We're looking to find how many times 85 goes into 661408.

Advancing to step 1:
6 divided by 85 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 85

Step 2:
When dividing 66 by 85, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 85

Moving on to step 3:
The number 85 fits into 661 7 times, leaving a remainder of 66.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 66 after subtracting 595 from 661.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 85

Moving on to step 4:
The number 85 fits into 664 7 times, leaving a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we take 595 away from 664, we end up with 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 85

Going ahead to step 5:
690 divided by 85 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 778.0
The remainder is 10 after subtracting 680 from 690.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 85

On to step 6:
85 can be fit into 108 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 7781.0
If we subtract 85 from 108, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
85 goes into 230 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 7781.2
Subtract 170 from 230 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 85 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 7781.27
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7781.27
Deduct 0 from 50 and we're left 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 10:
85 goes into 500 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7781.2705
If we subtract 425 from 500, we get 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 11:
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: 7781.27058
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 12:
700 divided by 85 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 7781.270588
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.

Our division results in 7781.270588 with a remaining 2e-06.
