We look at the division of 377831 by 81 
We're looking to find how many times 81 goes into 377831.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 81

Going ahead to step 2:
If we divide 37 by 81, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 81

Going ahead to step 3:
When dividing 377 by 81, we get 4 with a remainder of 53.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 324 from 377 and we're left with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 81

Let's proceed to step 4:
If we divide 538 by 81, we get 6 and a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 486 from 538, we get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 81

Step 5:
81 goes into 523 6 times with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Subtracting 486 from 523 leaves us with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 81

Moving on to step 6:
When dividing 371 by 81, we get 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4664.0
Subtract 324 from 371 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
81 goes into 470 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 4664.5
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
81 goes into 650 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4664.58
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
81 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 4664.58
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
81 goes into 200 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 4664.5802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 4664.58024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
81 goes into 560 6 times with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 4664.580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
740 divided by 81 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4664.5802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
81 goes into 110 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 4664.58024691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 4664.58024691 with a remaining 2.9e-08.
