We divide 76131712 by 81
Our goal is to divide 76131712 by 81.

Moving on to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 81

On to step 2:
When dividing 76 by 81, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 81

Advancing to step 3:
81 can be fit into 761 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 729 from 761 to get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 81

On to step 4:
323 divided by 81 is 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 93.0
The remainder is 80 after subtracting 243 from 323.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 81

Advancing to step 5:
81 can be fit into 801 9 times, resulting in a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 939.0
Deduct 729 from 801 and we're left with 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 81

Going ahead to step 6:
If we divide 727 by 81, we get 8 and a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 9398.0
Subtract 648 from 727 to get 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 81

Advancing to step 7:
81 goes into 791 9 times with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 93989.0
Deduct 729 from 791 and we're left with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 81

Step 8:
If we divide 622 by 81, we get 7 and a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 939897.0
Deduct 567 from 622 and we're left with 55.
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 9:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 939897.6
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
When dividing 640 by 81, we get 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 939897.67
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 939897.679
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
When dividing 10 by 81, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 939897.679
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
81 can be fit into 100 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 939897.67901
Deduct 81 from 100 and we're left 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.

Advancing to step 14:
81 goes into 190 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 939897.679012
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 15:
81 goes into 280 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 939897.6790123
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 16:
81 goes into 370 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 939897.67901234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 939897.67901234, with a leftover of 4.6e-08.
