We look at the division of 612903 by 81 
Our goal is to divide 612903 by 81.

Going ahead to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 81

Advancing to step 2:
The number 81 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 81

On to step 3:
81 can be fit into 612 7 times, resulting in a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 567 away from 612, we end up with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 81

Moving on to step 4:
If we divide 459 by 81, we get 5 and a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 54 after subtracting 405 from 459.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 81

Advancing to step 5:
The number 81 fits into 540 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 756.0
If we subtract 486 from 540, we get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 81

Moving on to step 6:
81 goes into 543 6 times with a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 7566.0
The remainder is 57 after subtracting 486 from 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
When dividing 570 by 81, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7566.7
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
81 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7566.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 81 fits into 300 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 7566.703
If we take 243 away from 300, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
570 divided by 81 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7566.7037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 81 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 7566.7037
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
81 goes into 300 3 times with a remainder of 57.
The next digit of our result is 3. 
Result so far: 7566.703703
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
If we divide 570 by 81, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7566.7037037
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
If we divide 30 by 81, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7566.7037037
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 7566.7037037 with a remaining 3e-08.
