We look at the division of 300689 by 85 
Let's see how many times 85 fits into 300689.

Going ahead to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 85

Advancing to step 2:
30 divided by 85 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 85

Moving on to step 3:
300 divided by 85 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 255 from 300 leaves us with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 85

Let's proceed to step 4:
85 goes into 456 5 times with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 425 from 456 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 85

Moving on to step 5:
When dividing 318 by 85, we get 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 353.0
Subtract 255 from 318 to get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 85

On to step 6:
The number 85 fits into 639 7 times, leaving a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 3537.0
Subtracting 595 from 639 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
When dividing 440 by 85, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3537.5
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.

Step 8:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 3537.51
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.

Let's proceed to step 9:
If we divide 650 by 85, we get 7 and a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 3537.517
Deduct 595 from 650 and we're left with 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:
If we divide 550 by 85, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 3537.5176
If we take 510 away from 550, we end up with 40.
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.
Write down 4 as next digit of the result. 
Result so far: 3537.51764
Subtract 340 from 400 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 12:
85 goes into 600 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 3537.517647
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.

Advancing to step 13:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 3537.517647
If we subtract 0 from 50, 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.

Step 14:
85 goes into 500 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 3537.51764705
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.

The final result is 3537.51764705 with a remainder of 7.5e-08.
