81303680 divided by 524 
Our goal is to divide 81303680 by 524.

Step 1:
8 divided by 524 is 0 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.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 524

Let's proceed to step 2:
The number 524 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 524

Moving on to step 3:
813 divided by 524 is 1 with a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 524 from 813 and we're left with 289.
Take the next digit (0) from the dividend and append it to 289, then repeat: 2890 / 524

Moving on to step 4:
The number 524 fits into 2890 5 times, leaving a remainder of 270.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2620 from 2890 and we're left with 270.
Bring next digit (3) of the dividend behind the 270 and repeat the process: 2703 / 524

Let's proceed to step 5:
524 can be fit into 2703 5 times, resulting in a remainder of 83.
Write down 5 as next digit of the result. 
Result so far: 155.0
Subtract 2620 from 2703 to get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 524

Let's proceed to step 6:
524 can be fit into 836 1 times, resulting in a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1551.0
The remainder is 312 after subtracting 524 from 836.
Include the next digit (8) from the dividend after 312, then repeat: 3128 / 524

Moving on to step 7:
524 goes into 3128 5 times with a remainder of 508.
Put 5 as the next digit of the answer. 
Result so far: 15515.0
Subtracting 2620 from 3128 leaves us with 508.
Fetch the next digit (0) from the dividend, attach it to 508 and continue: 5080 / 524

Advancing to step 8:
When dividing 5080 by 524, we get 9 with a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 155159.0
Subtracting 4716 from 5080 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 9:
524 goes into 3640 6 times with a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 155159.6
Subtract 3144 from 3640 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 10:
524 goes into 4960 9 times with a remainder of 244.
Use 9 as the next digit of our solution. 
Result so far: 155159.69
The remainder is 244 after subtracting 4716 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
2440 divided by 524 is 4 with a remainder of 344.
Use 4 as the next digit of our solution. 
Result so far: 155159.694
If we take 2096 away from 2440, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 12:
524 goes into 3440 6 times with a remainder of 296.
The next digit of our result is 6. 
Result so far: 155159.6946
The remainder is 296 after subtracting 3144 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 13:
524 can be fit into 2960 5 times, resulting in a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 155159.69465
Deduct 2620 from 2960 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 14:
3400 divided by 524 is 6 with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 155159.694656
If we subtract 3144 from 3400, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
524 can be fit into 2560 4 times, resulting in a remainder of 464.
Write down 4 as next digit of the result. 
Result so far: 155159.6946564
Subtracting 2096 from 2560 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 16:
524 can be fit into 4640 8 times, resulting in a remainder of 448.
The next digit of our result is 8. 
Result so far: 155159.69465648
If we subtract 4192 from 4640, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 155159.69465648, with a leftover of 4.48e-07.
