We look at the division of 15858474 by 357 
Let's see how many times 357 fits into 15858474.

Let's proceed to step 1:
357 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 357

Moving on to step 2:
When dividing 15 by 357, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 357

Moving on to step 3:
The number 357 fits into 158 0 times, leaving a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Bring next digit (5) of the dividend behind the 158 and repeat the process: 1585 / 357

On to step 4:
357 can be fit into 1585 4 times, resulting in a remainder of 157.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1428 from 1585 to get 157.
Include the next digit (8) from the dividend after 157, then repeat: 1578 / 357

Going ahead to step 5:
When dividing 1578 by 357, we get 4 with a remainder of 150.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 1428 from 1578, we get 150.
Bring next digit (4) of the dividend behind the 150 and repeat the process: 1504 / 357

Going ahead to step 6:
357 goes into 1504 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 444.0
If we take 1428 away from 1504, we end up with 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 357

Advancing to step 7:
357 can be fit into 767 2 times, resulting in a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 4442.0
The remainder is 53 after subtracting 714 from 767.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 357

Moving on to step 8:
357 goes into 534 1 times with a remainder of 177.
Put 1 as the next digit of the answer. 
Result so far: 44421.0
If we take 357 away from 534, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 9:
1770 divided by 357 is 4 with a remainder of 342.
Write down 4 as next digit of the result. 
Result so far: 44421.4
Deduct 1428 from 1770 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 10:
3420 divided by 357 is 9 with a remainder of 207.
The number 9 becomes the next digit in our result. 
Result so far: 44421.49
Subtracting 3213 from 3420 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 11:
The number 357 fits into 2070 5 times, leaving a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 44421.495
Deduct 1785 from 2070 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 12:
If we divide 2850 by 357, we get 7 and a remainder of 351.
The next digit of our result is 7. 
Result so far: 44421.4957
Subtracting 2499 from 2850 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
357 can be fit into 3510 9 times, resulting in a remainder of 297.
Put 9 as the next digit of the answer. 
Result so far: 44421.49579
Subtracting 3213 from 3510 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 14:
If we divide 2970 by 357, we get 8 and a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 44421.495798
Deduct 2856 from 2970 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 15:
When dividing 1140 by 357, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 44421.4957983
If we subtract 1071 from 1140, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 16:
357 can be fit into 690 1 times, resulting in a remainder of 333.
Record the quotient 1 as the next digit in the result. 
Result so far: 44421.49579831
Subtracting 357 from 690 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

The final outcome is 44421.49579831, with a leftover of 3.33e-07.
