278152 ÷ 81 
We want to figure out the number of times 278152 can be divided by 81.

Step 1:
81 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 81

Moving on to step 2:
81 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 81

Let's proceed to step 3:
When dividing 278 by 81, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 243 from 278 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 81

Advancing to step 4:
81 goes into 351 4 times with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 324 from 351 leaves us with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 81

Let's proceed to step 5:
If we divide 275 by 81, we get 3 and a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
Deduct 243 from 275 and we're left with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 81

Step 6:
81 goes into 322 3 times with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 3433.0
Subtracting 243 from 322 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
81 can be fit into 790 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 3433.9
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 8:
When dividing 610 by 81, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 3433.97
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
81 goes into 430 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3433.975
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
81 can be fit into 250 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3433.9753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
If we divide 70 by 81, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 3433.9753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
When dividing 700 by 81, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 3433.975308
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
When dividing 520 by 81, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 3433.9753086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3433.97530864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3433.97530864, with a leftover of 1.6e-08.
