We look at the division of 348431 by 81 
We're looking to find how many times 81 goes into 348431.

On to step 1:
3 divided by 81 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 81

Step 2:
81 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 81

Going ahead to step 3:
When dividing 348 by 81, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 324 from 348, we get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 81

Moving on to step 4:
If we divide 244 by 81, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 243 away from 244, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 81

Let's proceed to step 5:
If we divide 13 by 81, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 430.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 81

Advancing to step 6:
131 divided by 81 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 4301.0
If we take 81 away from 131, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
500 divided by 81 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4301.6
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
81 can be fit into 140 1 times, resulting in a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 4301.61
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 81, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 4301.617
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
81 can be fit into 230 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 4301.6172
Deduct 162 from 230 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
680 divided by 81 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 4301.61728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
When dividing 320 by 81, we get 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 4301.617283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 13:
The number 81 fits into 770 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4301.6172839
The remainder is 41 after subtracting 729 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
If we divide 410 by 81, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4301.61728395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 4301.61728395, with a leftover of 5e-09.
