We divide 161809 by 86
We're looking to find how many times 86 goes into 161809.

Advancing to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 86

Going ahead to step 2:
If we divide 16 by 86, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 86

Going ahead to step 3:
86 can be fit into 161 1 times, resulting in a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 161 to get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 86

Let's proceed to step 4:
If we divide 758 by 86, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 688 away from 758, we end up with 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 86

Moving on to step 5:
If we divide 700 by 86, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 688 from 700 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 86

Advancing to step 6:
129 divided by 86 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1881.0
Subtracting 86 from 129 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
When dividing 430 by 86, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1881.5
Subtracting 430 from 430 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
86 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1881.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
86 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1881.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1881.5 with a remainder of 0.0.
