661769 divided by 85 
We want to divide 661769 by 85.

Step 1:
85 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 85

Advancing to step 2:
85 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 85

Going ahead 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.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 85

Advancing to step 4:
The number 85 fits into 667 7 times, leaving a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtract 595 from 667 to get 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 85

Step 5:
If we divide 726 by 85, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
The remainder is 46 after subtracting 680 from 726.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 85

Let's proceed to step 6:
85 can be fit into 469 5 times, resulting in a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 7785.0
The remainder is 44 after subtracting 425 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 85 fits into 440 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 7785.5
Deduct 425 from 440 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 7785.51
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
85 goes into 650 7 times with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 7785.517
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 85, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 7785.5176
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
85 goes into 400 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 7785.51764
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 85, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7785.517647
If we take 595 away from 600, we end up 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.

Let's proceed to step 13:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7785.517647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 85 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 7785.51764705
If we take 425 away from 500, we end up 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.

In conclusion, the division gives 7785.51764705 with a balance of 7.5e-08.
