350003 divided by 81 
Our goal is to divide 350003 by 81.

Going ahead to step 1:
3 divided by 81 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 81

On to step 2:
When dividing 35 by 81, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 81

Moving on to step 3:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 324 away from 350, we end up with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 81

Going ahead to step 4:
260 divided by 81 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 243 from 260 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 81

Step 5:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 432.0
Subtract 162 from 170 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 81

Let's proceed to step 6:
When dividing 83 by 81, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4321.0
If we take 81 away from 83, we end up 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.

Moving on to step 7:
If we divide 20 by 81, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4321.0
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.

Moving on to step 8:
81 can be fit into 200 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 4321.02
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
81 goes into 380 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 4321.024
Subtracting 324 from 380 leaves us 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.

Going ahead to step 10:
81 goes into 560 6 times with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 4321.0246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
The number 81 fits into 740 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4321.02469
If we take 729 away from 740, we end up with 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 12:
When dividing 110 by 81, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 4321.024691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 81 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4321.0246913
Deduct 243 from 290 and we're left with 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 14:
470 divided by 81 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 4321.02469135
If we take 405 away from 470, we end up 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.

After the division, we end up with 4321.02469135 and a remainder of 6.5e-08.
