6128858 ÷ 357 
Our goal is to divide 6128858 by 357.

Let's proceed to step 1:
357 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 357

On to step 2:
357 goes into 61 0 times with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 357

On to step 3:
The number 357 fits into 612 1 times, leaving a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 255 after subtracting 357 from 612.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 357

Advancing to step 4:
If we divide 2558 by 357, we get 7 and a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 2499 from 2558 to get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 357

Let's proceed to step 5:
357 goes into 598 1 times with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 171.0
If we take 357 away from 598, we end up with 241.
Bring next digit (5) of the dividend behind the 241 and repeat the process: 2415 / 357

On to step 6:
If we divide 2415 by 357, we get 6 and a remainder of 273.
Write down 6 as next digit of the result. 
Result so far: 1716.0
Subtracting 2142 from 2415 leaves us with 273.
Bring next digit (8) of the dividend behind the 273 and repeat the process: 2738 / 357

On to step 7:
357 goes into 2738 7 times with a remainder of 239.
The next digit of our result is 7. 
Result so far: 17167.0
Deduct 2499 from 2738 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 8:
When dividing 2390 by 357, we get 6 with a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 17167.6
Subtract 2142 from 2390 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
357 goes into 2480 6 times with a remainder of 338.
Use 6 as the next digit of our solution. 
Result so far: 17167.66
Subtracting 2142 from 2480 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final outcome is 17167.66, with a leftover of 0.338.
