We look at the division of 333978 by 81 
We're looking to find how many times 81 goes into 333978.

Advancing to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 81

Advancing to step 2:
81 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 81

Going ahead to step 3:
When dividing 333 by 81, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 324 away from 333, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 81

Step 4:
When dividing 99 by 81, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 81 from 99, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 81

Advancing to step 5:
When dividing 187 by 81, we get 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 412.0
Deduct 162 from 187 and we're left with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 81

On to step 6:
258 divided by 81 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 4123.0
Subtracting 243 from 258 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
81 goes into 150 1 times with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 4123.1
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
81 goes into 690 8 times with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 4123.18
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4123.185
If we subtract 405 from 420, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
If we divide 150 by 81, we get 1 and a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 4123.1851
If we take 81 away from 150, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
690 divided by 81 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 4123.18518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 81 fits into 420 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 4123.185185
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
81 goes into 150 1 times with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 4123.1851851
If we subtract 81 from 150, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
690 divided by 81 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 4123.18518518
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 4123.18518518, with a leftover of 4.2e-08.
