801186 ÷ 87 
We're looking to find how many times 87 goes into 801186.

On to step 1:
87 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 87

Step 2:
80 divided by 87 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 87

Let's proceed to step 3:
87 goes into 801 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 18 after subtracting 783 from 801.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 87

Advancing to step 4:
If we divide 181 by 87, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we take 174 away from 181, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 87

Moving on to step 5:
The number 87 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 920.0
If we take 0 away from 78, we end up with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 87

Let's proceed to step 6:
If we divide 786 by 87, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9209.0
Deduct 783 from 786 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
87 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9209.0
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.

Let's proceed to step 8:
The number 87 fits into 300 3 times, leaving a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 9209.03
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 9209.034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 87 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 9209.0344
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 9209.0344 with a remainder of 0.00072.
