Let's divide 671589 by 85
We want to divide 671589 by 85.

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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 85

Moving on to step 2:
The number 85 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 85

Let's proceed to step 3:
671 divided by 85 is 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 7.0
If we take 595 away from 671, we end up with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 85

Moving on to step 4:
If we divide 765 by 85, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 765 from 765, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 85

Let's proceed to step 5:
If we divide 8 by 85, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 790.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 85

On to step 6:
If we divide 89 by 85, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 7901.0
Deduct 85 from 89 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 85 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7901.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 85, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 7901.04
Subtracting 340 from 400 leaves us 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 9:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7901.047
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.

On to step 10:
If we divide 50 by 85, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7901.047
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
When dividing 500 by 85, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7901.04705
The remainder is 75 after subtracting 425 from 500.
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 12:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 7901.047058
Subtract 680 from 750 to 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.

Let's proceed to step 13:
85 goes into 700 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 7901.0470588
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.

The final result is 7901.0470588 with a remainder of 2e-07.
