Let's divide 300145 by 81
We want to figure out the number of times 300145 can be divided by 81.

Let's proceed to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 81

Let's proceed to step 2:
30 divided by 81 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 81

On to step 3:
The number 81 fits into 300 3 times, leaving a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 243 from 300 leaves us with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 81

Let's proceed to step 4:
If we divide 571 by 81, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 567 from 571, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 81

Going ahead to step 5:
The number 81 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 370.0
If we subtract 0 from 44, we get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 81

Step 6:
The number 81 fits into 445 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 3705.0
If we subtract 405 from 445, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 3705.4
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
81 goes into 760 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 3705.49
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.

Step 9:
81 goes into 310 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 3705.493
If we take 243 away from 310, we end up with 67.
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 10:
670 divided by 81 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 3705.4938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 3705.49382
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.

Moving on to step 12:
81 can be fit into 580 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 3705.493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
If we divide 130 by 81, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 3705.4938271
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
490 divided by 81 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 3705.49382716
If we take 486 away from 490, we end up 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.

Our division results in 3705.49382716 with a remaining 4e-09.
