Let's divide 12863892 by 345
Our goal is to divide 12863892 by 345.

Going ahead to step 1:
If we divide 1 by 345, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 345

Moving on to step 2:
345 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 345

Advancing to step 3:
When dividing 128 by 345, we get 0 with a remainder of 128.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Grab the next digit (6) from the dividend, add it to 128, then carry on: 1286 / 345

Step 4:
1286 divided by 345 is 3 with a remainder of 251.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 251 after subtracting 1035 from 1286.
Fetch the next digit (3) from the dividend, attach it to 251 and continue: 2513 / 345

Step 5:
345 goes into 2513 7 times with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 2415 from 2513 and we're left with 98.
Grab the next digit (8) from the dividend, add it to 98, then carry on: 988 / 345

Advancing to step 6:
345 goes into 988 2 times with a remainder of 298.
Use 2 as the next digit of our solution. 
Result so far: 372.0
If we take 690 away from 988, we end up with 298.
Append the next digit (9) from the dividend to 298 and continue with: 2989 / 345

Going ahead to step 7:
When dividing 2989 by 345, we get 8 with a remainder of 229.
The next digit of our result is 8. 
Result so far: 3728.0
Subtract 2760 from 2989 to get 229.
Fetch the next digit (2) from the dividend, attach it to 229 and continue: 2292 / 345

Step 8:
345 goes into 2292 6 times with a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 37286.0
Subtract 2070 from 2292 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 9:
When dividing 2220 by 345, we get 6 with a remainder of 150.
Put 6 as the next digit of the answer. 
Result so far: 37286.6
Subtract 2070 from 2220 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
If we divide 1500 by 345, we get 4 and a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 37286.64
If we take 1380 away from 1500, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
The number 345 fits into 1200 3 times, leaving a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 37286.643
If we take 1035 away from 1200, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 12:
When dividing 1650 by 345, we get 4 with a remainder of 270.
Write down 4 as next digit of the result. 
Result so far: 37286.6434
The remainder is 270 after subtracting 1380 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
When dividing 2700 by 345, we get 7 with a remainder of 285.
The next digit of our result is 7. 
Result so far: 37286.64347
If we take 2415 away from 2700, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 14:
When dividing 2850 by 345, we get 8 with a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 37286.643478
If we subtract 2760 from 2850, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 15:
900 divided by 345 is 2 with a remainder of 210.
The number 2 becomes the next digit in our result. 
Result so far: 37286.6434782
Subtracting 690 from 900 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 16:
345 goes into 2100 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 37286.64347826
The remainder is 30 after subtracting 2070 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 37286.64347826 with a remainder of 3e-08.
