7104270 ÷ 558 
We want to figure out the number of times 7104270 can be divided by 558.

Moving on to step 1:
The number 558 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 558

Let's proceed to step 2:
558 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 558

Moving on to step 3:
If we divide 710 by 558, we get 1 and a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 558 from 710, we get 152.
Bring next digit (4) of the dividend behind the 152 and repeat the process: 1524 / 558

Advancing to step 4:
558 goes into 1524 2 times with a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1116 from 1524, we get 408.
Take the next digit (2) from the dividend and append it to 408, then repeat: 4082 / 558

On to step 5:
When dividing 4082 by 558, we get 7 with a remainder of 176.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtract 3906 from 4082 to get 176.
Bring next digit (7) of the dividend behind the 176 and repeat the process: 1767 / 558

Let's proceed to step 6:
When dividing 1767 by 558, we get 3 with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 1273.0
Subtracting 1674 from 1767 leaves us with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 558

Let's proceed to step 7:
930 divided by 558 is 1 with a remainder of 372.
Write down 1 as next digit of the result. 
Result so far: 12731.0
If we subtract 558 from 930, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 8:
When dividing 3720 by 558, we get 6 with a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 12731.6
Deduct 3348 from 3720 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 9:
558 can be fit into 3720 6 times, resulting in a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 12731.66
The remainder is 372 after subtracting 3348 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 12731.66, with a leftover of 0.372.
