We're dividing 81599274 by 531 
Let's see how many times 531 fits into 81599274.

Moving on to step 1:
8 divided by 531 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 531

Advancing to step 2:
531 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 531

Let's proceed to step 3:
815 divided by 531 is 1 with a remainder of 284.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 531 from 815 to get 284.
Bring next digit (9) of the dividend behind the 284 and repeat the process: 2849 / 531

On to step 4:
531 goes into 2849 5 times with a remainder of 194.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2655 away from 2849, we end up with 194.
Take the next digit (9) from the dividend and append it to 194, then repeat: 1949 / 531

On to step 5:
If we divide 1949 by 531, we get 3 and a remainder of 356.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we subtract 1593 from 1949, we get 356.
Include the next digit (2) from the dividend after 356, then repeat: 3562 / 531

Advancing to step 6:
3562 divided by 531 is 6 with a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 1536.0
Deduct 3186 from 3562 and we're left with 376.
Fetch the next digit (7) from the dividend, attach it to 376 and continue: 3767 / 531

Moving on to step 7:
The number 531 fits into 3767 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 15367.0
Deduct 3717 from 3767 and we're left with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 531

On to step 8:
If we divide 504 by 531, we get 0 and a remainder of 504.
The next digit of our result is 0. 
Result so far: 153670.0
Subtracting 0 from 504 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 9:
The number 531 fits into 5040 9 times, leaving a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 153670.9
Deduct 4779 from 5040 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 10:
If we divide 2610 by 531, we get 4 and a remainder of 486.
Put 4 as the next digit of the answer. 
Result so far: 153670.94
Deduct 2124 from 2610 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 11:
4860 divided by 531 is 9 with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 153670.949
If we take 4779 away from 4860, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
If we divide 810 by 531, we get 1 and a remainder of 279.
Use 1 as the next digit of our solution. 
Result so far: 153670.9491
If we subtract 531 from 810, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 13:
531 can be fit into 2790 5 times, resulting in a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 153670.94915
Subtracting 2655 from 2790 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 14:
The number 531 fits into 1350 2 times, leaving a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 153670.949152
Subtract 1062 from 1350 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
The number 531 fits into 2880 5 times, leaving a remainder of 225.
The next digit of our result is 5. 
Result so far: 153670.9491525
Subtract 2655 from 2880 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 16:
When dividing 2250 by 531, we get 4 with a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 153670.94915254
If we subtract 2124 from 2250, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 153670.94915254, with a leftover of 1.26e-07.
