We look at the division of 57158115 by 7 
We're looking to find how many times 7 goes into 57158115.

Advancing to step 1:
When dividing 5 by 7, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 7

Going ahead to step 2:
7 goes into 57 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 56 from 57 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 7

Advancing to step 3:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 7 away from 11, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

On to step 4:
45 divided by 7 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
If we take 42 away from 45, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 7

On to step 5:
7 can be fit into 38 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 8165.0
Deduct 35 from 38 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 7

Going ahead to step 6:
7 can be fit into 31 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 81654.0
Deduct 28 from 31 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 7

Step 7:
If we divide 31 by 7, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 816544.0
If we subtract 28 from 31, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 7

Let's proceed to step 8:
The number 7 fits into 35 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8165445.0
Subtract 35 from 35 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.

On to step 9:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8165445.0
Deduct 0 from 0 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.

On to step 10:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8165445.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8165445.0 with a balance of 0.0.
