We're dividing 171408 by 87 
We want to divide 171408 by 87.

Advancing to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 87

On to step 2:
The number 87 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 87

Let's proceed to step 3:
If we divide 171 by 87, we get 1 and a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 87 away from 171, we end up with 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 87

Advancing to step 4:
87 can be fit into 844 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 783 from 844, we get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 87

Advancing to step 5:
The number 87 fits into 610 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Subtract 609 from 610 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 87

Let's proceed to step 6:
When dividing 18 by 87, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 1970.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
If we divide 180 by 87, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 1970.2
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 87, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1970.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 87 fits into 600 6 times, leaving a remainder of 78.
The next digit of our result is 6. 
Result so far: 1970.206
If we subtract 522 from 600, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
If we divide 780 by 87, we get 8 and a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 1970.2068
If we subtract 696 from 780, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
87 can be fit into 840 9 times, resulting in a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 1970.20689
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
When dividing 570 by 87, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 1970.206896
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
87 goes into 480 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1970.2068965
If we take 435 away from 480, we end up 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.

Going ahead to step 14:
87 can be fit into 450 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1970.20689655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 1970.20689655, and the remainder is 1.5e-08.
