Let's divide 315428 by 81
We want to figure out the number of times 315428 can be divided by 81.

Advancing to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 81

Going ahead to step 2:
31 divided by 81 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 81

Let's proceed to step 3:
When dividing 315 by 81, we get 3 with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 72 after subtracting 243 from 315.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 81

Moving on to step 4:
When dividing 724 by 81, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 648 away from 724, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 81

Let's proceed to step 5:
When dividing 762 by 81, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 389.0
If we take 729 away from 762, we end up with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 81

Step 6:
81 can be fit into 338 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3894.0
If we subtract 324 from 338, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
81 can be fit into 140 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 3894.1
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
81 can be fit into 590 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 3894.17
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
The number 81 fits into 230 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 3894.172
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.

Moving on to step 10:
81 can be fit into 680 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 3894.1728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
320 divided by 81 is 3 with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 3894.17283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
When dividing 770 by 81, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 3894.172839
Subtracting 729 from 770 leaves us 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.

Advancing to step 13:
When dividing 410 by 81, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3894.1728395
If we take 405 away from 410, we end up 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.

Going ahead to step 14:
50 divided by 81 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 3894.1728395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 3894.1728395 with a remainder of 5e-08.
