We look at the division of 431786 by 85 
Let's see how many times 85 fits into 431786.

Going ahead to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 85

On to step 2:
85 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 85

Advancing to step 3:
If we divide 431 by 85, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 425 away from 431, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 85

Step 4:
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: 50.0
If we take 0 away from 67, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 85

Going ahead to step 5:
The number 85 fits into 678 7 times, leaving a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 507.0
Subtracting 595 from 678 leaves us with 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 85

Step 6:
836 divided by 85 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 5079.0
Deduct 765 from 836 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
When dividing 710 by 85, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 5079.8
Deduct 680 from 710 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
85 can be fit into 300 3 times, resulting in a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 5079.83
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
85 can be fit into 450 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5079.835
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
When dividing 250 by 85, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 5079.8352
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 5079.83529
Subtracting 765 from 800 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
85 goes into 350 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 5079.835294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 5079.8352941
Subtracting 85 from 100 leaves us 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.

Step 14:
150 divided by 85 is 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 5079.83529411
Subtracting 85 from 150 leaves us 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.

Our division results in 5079.83529411 with a remaining 6.5e-08.
