81264503 divided by 345 
We want to divide 81264503 by 345.

Let's proceed to step 1:
The number 345 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 345

Moving on to step 2:
If we divide 81 by 345, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 345

Moving on to step 3:
When dividing 812 by 345, we get 2 with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 690 from 812 leaves us with 122.
Bring next digit (6) of the dividend behind the 122 and repeat the process: 1226 / 345

Going ahead to step 4:
The number 345 fits into 1226 3 times, leaving a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 1035 from 1226 leaves us with 191.
Fetch the next digit (4) from the dividend, attach it to 191 and continue: 1914 / 345

On to step 5:
1914 divided by 345 is 5 with a remainder of 189.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
Subtracting 1725 from 1914 leaves us with 189.
Include the next digit (5) from the dividend after 189, then repeat: 1895 / 345

Advancing to step 6:
345 goes into 1895 5 times with a remainder of 170.
The next digit of our result is 5. 
Result so far: 2355.0
If we subtract 1725 from 1895, we get 170.
Include the next digit (0) from the dividend after 170, then repeat: 1700 / 345

Step 7:
When dividing 1700 by 345, we get 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 23554.0
Deduct 1380 from 1700 and we're left with 320.
Append the next digit (3) from the dividend to 320 and continue with: 3203 / 345

On to step 8:
345 goes into 3203 9 times with a remainder of 98.
The next digit of our result is 9. 
Result so far: 235549.0
If we subtract 3105 from 3203, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
980 divided by 345 is 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 235549.2
Deduct 690 from 980 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
When dividing 2900 by 345, we get 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 235549.28
Deduct 2760 from 2900 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
When dividing 1400 by 345, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 235549.284
If we subtract 1380 from 1400, we 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.

Going ahead to step 12:
If we divide 200 by 345, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 235549.284
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
When dividing 2000 by 345, we get 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 235549.28405
The remainder is 275 after subtracting 1725 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 14:
The number 345 fits into 2750 7 times, leaving a remainder of 335.
Use 7 as the next digit of our solution. 
Result so far: 235549.284057
Subtract 2415 from 2750 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 15:
345 can be fit into 3350 9 times, resulting in a remainder of 245.
The next digit of our result is 9. 
Result so far: 235549.2840579
If we subtract 3105 from 3350, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 16:
If we divide 2450 by 345, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 235549.28405797
Deduct 2415 from 2450 and we're left 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.

The final result is 235549.28405797 with a remainder of 3.5e-08.
