We look at the division of 25166771 by 357 
Let's see how many times 357 fits into 25166771.

Step 1:
357 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 357

Advancing to step 2:
If we divide 25 by 357, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 357

On to step 3:
357 can be fit into 251 0 times, resulting in a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 251 to get 251.
Fetch the next digit (6) from the dividend, attach it to 251 and continue: 2516 / 357

Advancing to step 4:
If we divide 2516 by 357, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 2499 away from 2516, we end up with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 357

On to step 5:
The number 357 fits into 176 0 times, leaving a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 176 and we're left with 176.
Bring next digit (7) of the dividend behind the 176 and repeat the process: 1767 / 357

Step 6:
The number 357 fits into 1767 4 times, leaving a remainder of 339.
Record the quotient 4 as the next digit in the result. 
Result so far: 704.0
The remainder is 339 after subtracting 1428 from 1767.
Grab the next digit (7) from the dividend, add it to 339, then carry on: 3397 / 357

Let's proceed to step 7:
The number 357 fits into 3397 9 times, leaving a remainder of 184.
The next digit of our result is 9. 
Result so far: 7049.0
The remainder is 184 after subtracting 3213 from 3397.
Include the next digit (1) from the dividend after 184, then repeat: 1841 / 357

Moving on to step 8:
If we divide 1841 by 357, we get 5 and a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 70495.0
If we take 1785 away from 1841, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 357 is 1 with a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 70495.1
If we subtract 357 from 560, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 10:
When dividing 2030 by 357, we get 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 70495.15
Subtracting 1785 from 2030 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 11:
If we divide 2450 by 357, we get 6 and a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 70495.156
If we take 2142 away from 2450, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 12:
357 goes into 3080 8 times with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 70495.1568
Subtracting 2856 from 3080 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 13:
357 can be fit into 2240 6 times, resulting in a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 70495.15686
Deduct 2142 from 2240 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 14:
980 divided by 357 is 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 70495.156862
If we take 714 away from 980, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 15:
2660 divided by 357 is 7 with a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 70495.1568627
The remainder is 161 after subtracting 2499 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 16:
1610 divided by 357 is 4 with a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 70495.15686274
Subtract 1428 from 1610 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 70495.15686274, with a leftover of 1.82e-07.
