We're dividing 54334173 by 81 
Let's see how many times 81 fits into 54334173.

On to step 1:
5 divided by 81 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 81

Going ahead to step 2:
If we divide 54 by 81, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 81

Going ahead to step 3:
81 can be fit into 543 6 times, resulting in a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 57 after subtracting 486 from 543.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 81

On to step 4:
573 divided by 81 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we take 567 away from 573, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 81

Step 5:
81 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 670.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 81

Advancing to step 6:
If we divide 641 by 81, we get 7 and a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 6707.0
Subtracting 567 from 641 leaves us with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 81

Advancing to step 7:
The number 81 fits into 747 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 67079.0
Subtracting 729 from 747 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 81

Let's proceed to step 8:
183 divided by 81 is 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 670792.0
If we take 162 away from 183, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
81 goes into 210 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 670792.2
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 81, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 670792.25
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
81 goes into 750 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 670792.259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 670792.2592
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
81 goes into 480 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 670792.25925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
81 goes into 750 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 670792.259259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 15:
81 goes into 210 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 670792.2592592
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
480 divided by 81 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 670792.25925925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 670792.25925925, with a leftover of 7.5e-08.
