We're dividing 81946439 by 764 
We want to divide 81946439 by 764.

Let's proceed to step 1:
The number 764 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 764

Step 2:
When dividing 81 by 764, we get 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.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 764

Advancing to step 3:
764 goes into 819 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 764 from 819 and we're left with 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 764

Going ahead to step 4:
The number 764 fits into 554 0 times, leaving a remainder of 554.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 554 and we're left with 554.
Grab the next digit (6) from the dividend, add it to 554, then carry on: 5546 / 764

Step 5:
The number 764 fits into 5546 7 times, leaving a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 198 after subtracting 5348 from 5546.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 764

Step 6:
When dividing 1984 by 764, we get 2 with a remainder of 456.
Record the quotient 2 as the next digit in the result. 
Result so far: 1072.0
If we take 1528 away from 1984, we end up with 456.
Take the next digit (3) from the dividend and append it to 456, then repeat: 4563 / 764

Going ahead to step 7:
The number 764 fits into 4563 5 times, leaving a remainder of 743.
The next digit of our result is 5. 
Result so far: 10725.0
Subtract 3820 from 4563 to get 743.
Bring next digit (9) of the dividend behind the 743 and repeat the process: 7439 / 764

Step 8:
The number 764 fits into 7439 9 times, leaving a remainder of 563.
Put 9 as the next digit of the answer. 
Result so far: 107259.0
Subtract 6876 from 7439 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 9:
If we divide 5630 by 764, we get 7 and a remainder of 282.
Put 7 as the next digit of the answer. 
Result so far: 107259.7
If we take 5348 away from 5630, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
When dividing 2820 by 764, we get 3 with a remainder of 528.
Write down 3 as next digit of the result. 
Result so far: 107259.73
If we take 2292 away from 2820, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 11:
764 goes into 5280 6 times with a remainder of 696.
Write down 6 as next digit of the result. 
Result so far: 107259.736
Subtract 4584 from 5280 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 12:
If we divide 6960 by 764, we get 9 and a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 107259.7369
Subtracting 6876 from 6960 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 13:
The number 764 fits into 840 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 107259.73691
The remainder is 76 after subtracting 764 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
The number 764 fits into 760 0 times, leaving a remainder of 760.
Use 0 as the next digit of our solution. 
Result so far: 107259.73691
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
The number 764 fits into 7600 9 times, leaving a remainder of 724.
Use 9 as the next digit of our solution. 
Result so far: 107259.7369109
If we subtract 6876 from 7600, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Moving on to step 16:
7240 divided by 764 is 9 with a remainder of 364.
Use 9 as the next digit of our solution. 
Result so far: 107259.73691099
If we take 6876 away from 7240, we end up 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.

In conclusion, the division gives 107259.73691099 with a balance of 3.64e-07.
