We're dividing 73370619 by 81 
We want to divide 73370619 by 81.

Let's proceed to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 81

Going ahead to step 2:
73 divided by 81 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 81

Moving on to step 3:
The number 81 fits into 733 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 729 from 733, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 81

On to step 4:
The number 81 fits into 47 0 times, leaving a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 47, we get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 81

On to step 5:
The number 81 fits into 470 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 905.0
If we subtract 405 from 470, we get 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 81

Advancing to step 6:
81 can be fit into 656 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 9058.0
Deduct 648 from 656 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 81

Step 7:
If we divide 81 by 81, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 90581.0
If we take 81 away from 81, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 81

On to step 8:
9 divided by 81 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 905810.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 81, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 905810.1
Deduct 81 from 90 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
81 goes into 90 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 905810.11
Subtract 81 from 90 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 905810.11 with a remainder of 0.009.
