We divide 10257012 by 345
We want to divide 10257012 by 345.

Advancing to step 1:
The number 345 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 345

Going ahead to step 2:
The number 345 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 345

On to step 3:
102 divided by 345 is 0 with a remainder of 102.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 102 to get 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 345

Moving on to step 4:
1025 divided by 345 is 2 with a remainder of 335.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 335 after subtracting 690 from 1025.
Include the next digit (7) from the dividend after 335, then repeat: 3357 / 345

Going ahead to step 5:
The number 345 fits into 3357 9 times, leaving a remainder of 252.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 252 after subtracting 3105 from 3357.
Bring next digit (0) of the dividend behind the 252 and repeat the process: 2520 / 345

Going ahead to step 6:
345 can be fit into 2520 7 times, resulting in a remainder of 105.
Put 7 as the next digit of the answer. 
Result so far: 297.0
The remainder is 105 after subtracting 2415 from 2520.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 345

Going ahead to step 7:
When dividing 1051 by 345, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 2973.0
Subtracting 1035 from 1051 leaves us with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 345

Going ahead to step 8:
345 can be fit into 162 0 times, resulting in a remainder of 162.
Write down 0 as next digit of the result. 
Result so far: 29730.0
Subtracting 0 from 162 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
1620 divided by 345 is 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 29730.4
If we subtract 1380 from 1620, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
345 can be fit into 2400 6 times, resulting in a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 29730.46
Deduct 2070 from 2400 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 11:
345 can be fit into 3300 9 times, resulting in a remainder of 195.
Put 9 as the next digit of the answer. 
Result so far: 29730.469
The remainder is 195 after subtracting 3105 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 12:
The number 345 fits into 1950 5 times, leaving a remainder of 225.
The next digit of our result is 5. 
Result so far: 29730.4695
If we subtract 1725 from 1950, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 13:
If we divide 2250 by 345, we get 6 and a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 29730.46956
Subtract 2070 from 2250 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
The number 345 fits into 1800 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 29730.469565
Deduct 1725 from 1800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
When dividing 750 by 345, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 29730.4695652
The remainder is 60 after subtracting 690 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
When dividing 600 by 345, we get 1 with a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 29730.46956521
The remainder is 255 after subtracting 345 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 29730.46956521 with a remainder of 2.55e-07.
