81738383 ÷ 531 
Our goal is to divide 81738383 by 531.

Advancing to step 1:
531 can be fit into 8 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 531

Going ahead to step 2:
81 divided by 531 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 531

Advancing to step 3:
531 can be fit into 817 1 times, resulting in a remainder of 286.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 286 after subtracting 531 from 817.
Include the next digit (3) from the dividend after 286, then repeat: 2863 / 531

Advancing to step 4:
When dividing 2863 by 531, we get 5 with a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2655 from 2863, we get 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 531

Advancing to step 5:
2088 divided by 531 is 3 with a remainder of 495.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Deduct 1593 from 2088 and we're left with 495.
Include the next digit (3) from the dividend after 495, then repeat: 4953 / 531

Going ahead to step 6:
If we divide 4953 by 531, we get 9 and a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 1539.0
Deduct 4779 from 4953 and we're left with 174.
Append the next digit (8) from the dividend to 174 and continue with: 1748 / 531

On to step 7:
531 can be fit into 1748 3 times, resulting in a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 15393.0
Subtracting 1593 from 1748 leaves us with 155.
Include the next digit (3) from the dividend after 155, then repeat: 1553 / 531

Moving on to step 8:
531 can be fit into 1553 2 times, resulting in a remainder of 491.
Use 2 as the next digit of our solution. 
Result so far: 153932.0
Subtract 1062 from 1553 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Let's proceed to step 9:
If we divide 4910 by 531, we get 9 and a remainder of 131.
The next digit of our result is 9. 
Result so far: 153932.9
Deduct 4779 from 4910 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 10:
The number 531 fits into 1310 2 times, leaving a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 153932.92
If we subtract 1062 from 1310, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
2480 divided by 531 is 4 with a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 153932.924
If we subtract 2124 from 2480, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 12:
When dividing 3560 by 531, we get 6 with a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 153932.9246
If we take 3186 away from 3560, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 13:
The number 531 fits into 3740 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 153932.92467
The remainder is 23 after subtracting 3717 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
531 can be fit into 230 0 times, resulting in a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 153932.92467
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 15:
531 can be fit into 2300 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 153932.9246704
Deduct 2124 from 2300 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
The number 531 fits into 1760 3 times, leaving a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 153932.92467043
Deduct 1593 from 1760 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

In conclusion, the division gives 153932.92467043 with a balance of 1.67e-07.
