81331848 divided by 812 
Our goal is to divide 81331848 by 812.

On to step 1:
812 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 812

Advancing to step 2:
812 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 812

Step 3:
If we divide 813 by 812, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 812 from 813 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 812

On to step 4:
If we divide 13 by 812, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 13, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 812

Moving on to step 5:
If we divide 131 by 812, we get 0 and a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 131 after subtracting 0 from 131.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 812

Advancing to step 6:
If we divide 1318 by 812, we get 1 and a remainder of 506.
The next digit of our result is 1. 
Result so far: 1001.0
If we subtract 812 from 1318, we get 506.
Append the next digit (4) from the dividend to 506 and continue with: 5064 / 812

Advancing to step 7:
The number 812 fits into 5064 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 10016.0
Subtracting 4872 from 5064 leaves us with 192.
Grab the next digit (8) from the dividend, add it to 192, then carry on: 1928 / 812

Moving on to step 8:
812 goes into 1928 2 times with a remainder of 304.
The next digit of our result is 2. 
Result so far: 100162.0
The remainder is 304 after subtracting 1624 from 1928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 9:
3040 divided by 812 is 3 with a remainder of 604.
The next digit of our result is 3. 
Result so far: 100162.3
If we take 2436 away from 3040, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 10:
When dividing 6040 by 812, we get 7 with a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 100162.37
Subtract 5684 from 6040 to 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.

Advancing to step 11:
812 goes into 3560 4 times with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 100162.374
Subtracting 3248 from 3560 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 12:
The number 812 fits into 3120 3 times, leaving a remainder of 684.
The number 3 becomes the next digit in our result. 
Result so far: 100162.3743
The remainder is 684 after subtracting 2436 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 13:
812 can be fit into 6840 8 times, resulting in a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 100162.37438
The remainder is 344 after subtracting 6496 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 14:
If we divide 3440 by 812, we get 4 and a remainder of 192.
The next digit of our result is 4. 
Result so far: 100162.374384
Deduct 3248 from 3440 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
When dividing 1920 by 812, we get 2 with a remainder of 296.
Write down 2 as next digit of the result. 
Result so far: 100162.3743842
Subtract 1624 from 1920 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 16:
812 can be fit into 2960 3 times, resulting in a remainder of 524.
The next digit of our result is 3. 
Result so far: 100162.37438423
If we take 2436 away from 2960, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final outcome is 100162.37438423, with a leftover of 5.24e-07.
