We're dividing 87742225 by 531 
Let's see how many times 531 fits into 87742225.

Step 1:
531 can be fit into 8 0 times, resulting in 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 531

Moving on to step 2:
The number 531 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 531

Let's proceed to step 3:
531 goes into 877 1 times with a remainder of 346.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 531 from 877 and we're left with 346.
Append the next digit (4) from the dividend to 346 and continue with: 3464 / 531

On to step 4:
531 can be fit into 3464 6 times, resulting in a remainder of 278.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 278 after subtracting 3186 from 3464.
Append the next digit (2) from the dividend to 278 and continue with: 2782 / 531

Going ahead to step 5:
531 can be fit into 2782 5 times, resulting in a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we take 2655 away from 2782, we end up with 127.
Include the next digit (2) from the dividend after 127, then repeat: 1272 / 531

Step 6:
The number 531 fits into 1272 2 times, leaving a remainder of 210.
The next digit of our result is 2. 
Result so far: 1652.0
If we take 1062 away from 1272, we end up with 210.
Fetch the next digit (2) from the dividend, attach it to 210 and continue: 2102 / 531

On to step 7:
531 goes into 2102 3 times with a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 16523.0
Subtracting 1593 from 2102 leaves us with 509.
Grab the next digit (5) from the dividend, add it to 509, then carry on: 5095 / 531

Let's proceed to step 8:
5095 divided by 531 is 9 with a remainder of 316.
The next digit of our result is 9. 
Result so far: 165239.0
If we subtract 4779 from 5095, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 9:
531 goes into 3160 5 times with a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 165239.5
If we subtract 2655 from 3160, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 10:
The number 531 fits into 5050 9 times, leaving a remainder of 271.
The next digit of our result is 9. 
Result so far: 165239.59
Subtract 4779 from 5050 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 11:
531 can be fit into 2710 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 165239.595
The remainder is 55 after subtracting 2655 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
When dividing 550 by 531, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 165239.5951
If we take 531 away from 550, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 531 fits into 190 0 times, leaving a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 165239.5951
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
531 can be fit into 1900 3 times, resulting in a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 165239.595103
If we take 1593 away from 1900, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 15:
If we divide 3070 by 531, we get 5 and a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 165239.5951035
If we take 2655 away from 3070, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 16:
If we divide 4150 by 531, we get 7 and a remainder of 433.
The next digit of our result is 7. 
Result so far: 165239.59510357
Deduct 3717 from 4150 and we're left with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Our division results in 165239.59510357 with a remaining 4.33e-07.
