310028 ÷ 81 
We want to divide 310028 by 81.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 81

On to step 2:
The number 81 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 81

Advancing to step 3:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 243 from 310, we get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 81

Step 4:
When dividing 670 by 81, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 648 away from 670, we end up with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 81

Advancing to step 5:
222 divided by 81 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 382.0
If we subtract 162 from 222, we get 60.
Include the next digit (8) from the dividend after 60, then repeat: 608 / 81

Let's proceed to step 6:
81 can be fit into 608 7 times, resulting in a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 3827.0
If we take 567 away from 608, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
If we divide 410 by 81, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3827.5
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 81, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3827.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
500 divided by 81 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 3827.506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
81 goes into 140 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 3827.5061
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 11:
590 divided by 81 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 3827.50617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
The number 81 fits into 230 2 times, leaving a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 3827.506172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 3827.5061728
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
81 goes into 320 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 3827.50617283
Subtracting 243 from 320 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

In conclusion, the division gives 3827.50617283 with a balance of 7.7e-08.
