12948556 ÷ 10 
We want to figure out the number of times 12948556 can be divided by 10.

On to step 1:
10 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 10

Going ahead to step 2:
When dividing 12 by 10, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 10 from 12, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 10

Advancing to step 3:
If we divide 29 by 10, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 9 after subtracting 20 from 29.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 10

Going ahead to step 4:
10 can be fit into 94 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 4 after subtracting 90 from 94.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 10

Step 5:
10 goes into 48 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1294.0
The remainder is 8 after subtracting 40 from 48.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 10

Advancing to step 6:
10 can be fit into 85 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 12948.0
Subtract 80 from 85 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 10

Advancing to step 7:
If we divide 55 by 10, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 129485.0
If we take 50 away from 55, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 10

Going ahead to step 8:
When dividing 56 by 10, we get 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 1294855.0
Subtracting 50 from 56 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 10, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1294855.6
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1294855.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1294855.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1294855.6, with a leftover of 0.0.
