We look at the division of 12909039 by 348 
Our goal is to divide 12909039 by 348.

Step 1:
The number 348 fits into 1 0 times, leaving 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 / 348

Going ahead to step 2:
The number 348 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 348

Moving on to step 3:
129 divided by 348 is 0 with a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Take the next digit (0) from the dividend and append it to 129, then repeat: 1290 / 348

Let's proceed to step 4:
The number 348 fits into 1290 3 times, leaving a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1044 away from 1290, we end up with 246.
Append the next digit (9) from the dividend to 246 and continue with: 2469 / 348

Going ahead to step 5:
2469 divided by 348 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 2436 from 2469 to get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 348

Moving on to step 6:
When dividing 330 by 348, we get 0 with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 370.0
If we subtract 0 from 330, we get 330.
Fetch the next digit (3) from the dividend, attach it to 330 and continue: 3303 / 348

Step 7:
When dividing 3303 by 348, we get 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 3709.0
If we take 3132 away from 3303, we end up with 171.
Include the next digit (9) from the dividend after 171, then repeat: 1719 / 348

Moving on to step 8:
The number 348 fits into 1719 4 times, leaving a remainder of 327.
Put 4 as the next digit of the answer. 
Result so far: 37094.0
If we subtract 1392 from 1719, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
The number 348 fits into 3270 9 times, leaving a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 37094.9
Subtract 3132 from 3270 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 10:
When dividing 1380 by 348, we get 3 with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 37094.93
Deduct 1044 from 1380 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
The number 348 fits into 3360 9 times, leaving a remainder of 228.
Put 9 as the next digit of the answer. 
Result so far: 37094.939
If we take 3132 away from 3360, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
The number 348 fits into 2280 6 times, leaving a remainder of 192.
The next digit of our result is 6. 
Result so far: 37094.9396
Subtracting 2088 from 2280 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
1920 divided by 348 is 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 37094.93965
Subtracting 1740 from 1920 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
When dividing 1800 by 348, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 37094.939655
The remainder is 60 after subtracting 1740 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 37094.939655 with a balance of 6e-06.
