Let's divide 743512 by 81
We want to figure out the number of times 743512 can be divided 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 subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 81

Let's proceed to step 2:
81 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 81

Advancing to step 3:
If we divide 743 by 81, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 729 from 743 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 81

Step 4:
81 goes into 145 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 81 from 145 to get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 81

Going ahead to step 5:
641 divided by 81 is 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 917.0
If we subtract 567 from 641, we get 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 81

Moving on to step 6:
If we divide 742 by 81, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 9179.0
Subtracting 729 from 742 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 81, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 9179.1
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
81 goes into 490 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9179.16
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
81 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9179.16
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 9179.1604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9179.16049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
310 divided by 81 is 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 9179.160493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 9179.1604938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 9179.16049382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 9179.16049382 with a remaining 5.8e-08.
