90120804 ÷ 357 
Let's see how many times 357 fits into 90120804.

Going ahead to step 1:
When dividing 9 by 357, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 357

Step 2:
90 divided by 357 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 357

Going ahead to step 3:
If we divide 901 by 357, we get 2 and a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 714 from 901 to get 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 357

On to step 4:
357 goes into 1872 5 times with a remainder of 87.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1785 from 1872 and we're left with 87.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 357

Let's proceed to step 5:
357 goes into 870 2 times with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we take 714 away from 870, we end up with 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 357

On to step 6:
When dividing 1568 by 357, we get 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 2524.0
If we subtract 1428 from 1568, we get 140.
Grab the next digit (0) from the dividend, add it to 140, then carry on: 1400 / 357

Let's proceed to step 7:
357 goes into 1400 3 times with a remainder of 329.
The number 3 becomes the next digit in our result. 
Result so far: 25243.0
Subtracting 1071 from 1400 leaves us with 329.
Fetch the next digit (4) from the dividend, attach it to 329 and continue: 3294 / 357

Step 8:
357 can be fit into 3294 9 times, resulting in a remainder of 81.
The next digit of our result is 9. 
Result so far: 252439.0
Subtract 3213 from 3294 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
When dividing 810 by 357, we get 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 252439.2
Subtracting 714 from 810 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
357 goes into 960 2 times with a remainder of 246.
The next digit of our result is 2. 
Result so far: 252439.22
Deduct 714 from 960 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final result is 252439.22 with a remainder of 0.246.
