178521 ÷ 87 
We're looking to find how many times 87 goes into 178521.

Advancing 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
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 87

Let's proceed to step 2:
87 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 87

Advancing to step 3:
178 divided by 87 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 4 after subtracting 174 from 178.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 87

Going ahead to step 4:
45 divided by 87 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 45 to get 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 87

Advancing to step 5:
87 can be fit into 452 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Deduct 435 from 452 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 87

Advancing to step 6:
87 can be fit into 171 1 times, resulting in a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 2051.0
Subtract 87 from 171 to 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.

Advancing to step 7:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 2051.9
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
The number 87 fits into 570 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 2051.96
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2051.965
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 10:
When dividing 450 by 87, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2051.9655
Subtract 435 from 450 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 2051.9655, with a leftover of 0.00015.
