We're dividing 378816 by 81 
Our goal is to divide 378816 by 81.

Moving on to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 81

Step 2:
The number 81 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 81

Let's proceed to step 3:
When dividing 378 by 81, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 324 from 378 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 81

Step 4:
If we divide 548 by 81, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 486 from 548, we get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 81

On to step 5:
81 can be fit into 621 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 467.0
Subtract 567 from 621 to get 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 81

On to step 6:
546 divided by 81 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 4676.0
Subtracting 486 from 546 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 81, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 4676.7
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
81 can be fit into 330 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4676.74
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
81 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4676.74
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
81 goes into 600 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 4676.7407
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
The number 81 fits into 330 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4676.74074
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4676.74074
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
If we divide 600 by 81, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 4676.7407407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 14:
81 goes into 330 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4676.74074074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4676.74074074 with a remainder of 6e-09.
