Let's divide 42158946 by 357
We want to divide 42158946 by 357.

Advancing to step 1:
357 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 357

Step 2:
357 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 357

Step 3:
When dividing 421 by 357, we get 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 357 from 421 leaves us with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 357

Let's proceed to step 4:
357 can be fit into 645 1 times, resulting in a remainder of 288.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 357 from 645 and we're left with 288.
Bring next digit (8) of the dividend behind the 288 and repeat the process: 2888 / 357

Going ahead to step 5:
2888 divided by 357 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtract 2856 from 2888 to get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 357

Going ahead to step 6:
329 divided by 357 is 0 with a remainder of 329.
Write down 0 as next digit of the result. 
Result so far: 1180.0
Deduct 0 from 329 and we're left with 329.
Append the next digit (4) from the dividend to 329 and continue with: 3294 / 357

Going ahead to step 7:
3294 divided by 357 is 9 with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 11809.0
Subtract 3213 from 3294 to get 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 357

Moving on to step 8:
The number 357 fits into 816 2 times, leaving a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 118092.0
If we subtract 714 from 816, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
357 can be fit into 1020 2 times, resulting in a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 118092.2
If we subtract 714 from 1020, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 10:
3060 divided by 357 is 8 with a remainder of 204.
The next digit of our result is 8. 
Result so far: 118092.28
Subtracting 2856 from 3060 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 11:
If we divide 2040 by 357, we get 5 and a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 118092.285
Subtracting 1785 from 2040 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 12:
If we divide 2550 by 357, we get 7 and a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 118092.2857
Subtracting 2499 from 2550 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
When dividing 510 by 357, we get 1 with a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 118092.28571
If we subtract 357 from 510, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 14:
The number 357 fits into 1530 4 times, leaving a remainder of 102.
The next digit of our result is 4. 
Result so far: 118092.285714
If we subtract 1428 from 1530, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
When dividing 1020 by 357, we get 2 with a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 118092.2857142
Deduct 714 from 1020 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 16:
When dividing 3060 by 357, we get 8 with a remainder of 204.
Record the quotient 8 as the next digit in the result. 
Result so far: 118092.28571428
Deduct 2856 from 3060 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 118092.28571428, with a leftover of 2.04e-07.
