We look at the division of 161685 by 85 
We want to figure out the number of times 161685 can be divided by 85.

Step 1:
1 divided by 85 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 85

Let's proceed to step 2:
16 divided by 85 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 85

Let's proceed to step 3:
The number 85 fits into 161 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 85 from 161 to get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 85

Going ahead to step 4:
If we divide 766 by 85, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 765 from 766 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 85

Step 5:
When dividing 18 by 85, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 18 to get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 85

On to step 6:
185 divided by 85 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 1902.0
If we take 170 away from 185, we end up 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 7:
When dividing 150 by 85, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1902.1
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.

On to step 8:
85 goes into 650 7 times with a remainder of 55.
The next digit of our result is 7. 
Result so far: 1902.17
If we take 595 away from 650, we end up 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 9:
The number 85 fits into 550 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 1902.176
Subtracting 510 from 550 leaves us 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.

Step 10:
400 divided by 85 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1902.1764
If we subtract 340 from 400, we 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.

Let's proceed to step 11:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1902.17647
The remainder is 5 after subtracting 595 from 600.
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 12:
If we divide 50 by 85, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1902.17647
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.

Moving on to step 13:
500 divided by 85 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1902.1764705
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.

Moving on to step 14:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 1902.17647058
Subtracting 680 from 750 leaves us 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.

The final outcome is 1902.17647058, with a leftover of 7e-08.
