We're dividing 428966 by 85 
Our goal is to divide 428966 by 85.

Advancing to step 1:
4 divided by 85 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 85

On to step 2:
42 divided by 85 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 85

On to step 3:
If we divide 428 by 85, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we take 425 away from 428, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 85

Step 4:
The number 85 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 85

Step 5:
If we divide 396 by 85, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 504.0
Subtracting 340 from 396 leaves us with 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 85

Advancing to step 6:
85 goes into 566 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 5046.0
Deduct 510 from 566 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
If we divide 560 by 85, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5046.6
If we subtract 510 from 560, we 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.

Going ahead to step 8:
85 goes into 500 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 5046.65
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.

Advancing to step 9:
When dividing 750 by 85, we get 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 5046.658
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
When dividing 700 by 85, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 5046.6588
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 outcome is 5046.6588, with a leftover of 0.0002.
