161780 ÷ 87 
We want to divide 161780 by 87.

Moving on to step 1:
87 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 87

Advancing to step 2:
87 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
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 / 87

Advancing to step 3:
87 can be fit into 161 1 times, resulting in a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 87 from 161, we get 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 87

On to step 4:
87 can be fit into 747 8 times, resulting in a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 51 after subtracting 696 from 747.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 87

On to step 5:
87 can be fit into 518 5 times, resulting in a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtracting 435 from 518 leaves us with 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 87

Advancing to step 6:
If we divide 830 by 87, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 1859.0
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
87 goes into 470 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1859.5
If we take 435 away from 470, we end up 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 8:
350 divided by 87 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1859.54
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 87 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1859.54
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
87 goes into 200 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 1859.5402
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
When dividing 260 by 87, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 1859.54022
Deduct 174 from 260 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 1859.54022 and a remainder of 8.6e-05.
