We're dividing 189690 by 87 
We want to figure out the number of times 189690 can be divided by 87.

Moving on to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 87

Going ahead to step 2:
If we divide 18 by 87, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 87

Let's proceed to step 3:
87 goes into 189 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 174 from 189 to get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 87

Step 4:
When dividing 156 by 87, we get 1 with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 87 from 156 to get 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 87

Let's proceed to step 5:
87 goes into 699 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we take 696 away from 699, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 87

Let's proceed to step 6:
When dividing 30 by 87, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2180.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
The number 87 fits into 300 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 2180.3
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 2180.34
Subtracting 348 from 390 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 2180.344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 2180.344 with a remaining 0.0072.
