We divide 531773 by 87
We want to figure out the number of times 531773 can be divided by 87.

On to step 1:
If we divide 5 by 87, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 87

Step 2:
87 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 87

Step 3:
If we divide 531 by 87, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 522 from 531 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 87

Step 4:
87 goes into 97 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 61.0
The remainder is 10 after subtracting 87 from 97.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 87

Step 5:
The number 87 fits into 107 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 611.0
If we take 87 away from 107, we end up with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 87

Step 6:
When dividing 203 by 87, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 6112.0
Deduct 174 from 203 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
The number 87 fits into 290 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 6112.3
Deduct 261 from 290 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
87 goes into 290 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 6112.33
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 6112.33 and a remainder of 0.029.
