We look at the division of 375389 by 81 
We want to figure out the number of times 375389 can be divided by 81.

Moving on to step 1:
3 divided by 81 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 81

Going ahead to step 2:
81 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 81

Let's proceed to step 3:
When dividing 375 by 81, we get 4 with a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 324 from 375 to get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 81

Step 4:
When dividing 513 by 81, we get 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 486 away from 513, we end up with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 81

Advancing to step 5:
81 can be fit into 278 3 times, resulting in a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
Deduct 243 from 278 and we're left with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 81

Moving on to step 6:
The number 81 fits into 359 4 times, leaving a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4634.0
Subtracting 324 from 359 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
81 goes into 350 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4634.4
If we subtract 324 from 350, we 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 8:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 4634.43
Subtract 243 from 260 to 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 9:
If we divide 170 by 81, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4634.432
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4634.432
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 81 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 4634.43209
Subtract 729 from 800 to 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.

Moving on to step 12:
81 goes into 710 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 4634.432098
If we take 648 away from 710, 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.

On to step 13:
The number 81 fits into 620 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 4634.4320987
Deduct 567 from 620 and we're left 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.

Moving on to step 14:
If we divide 530 by 81, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 4634.43209876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 4634.43209876 and a remainder of 4.4e-08.
