We're dividing 378089 by 81 
Our goal is to divide 378089 by 81.

Going ahead to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 81

On to 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
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 81

Let's proceed to step 3:
When dividing 378 by 81, we get 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 324 from 378, we get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 81

On to step 4:
The number 81 fits into 540 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 486 away from 540, we end up with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 81

Advancing to step 5:
548 divided by 81 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 466.0
The remainder is 62 after subtracting 486 from 548.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 81

Let's proceed to step 6:
629 divided by 81 is 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 4667.0
If we take 567 away from 629, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
When dividing 620 by 81, we get 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 4667.7
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 8:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4667.76
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
81 goes into 440 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4667.765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
81 goes into 350 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4667.7654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 4667.76543
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
When dividing 170 by 81, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4667.765432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 4667.765432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
81 goes into 800 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 4667.76543209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 4667.76543209 with a remainder of 7.1e-08.
