We're dividing 90521413 by 357 
Our goal is to divide 90521413 by 357.

Moving on to step 1:
357 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 357

Let's proceed to step 2:
If we divide 90 by 357, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 357

Step 3:
If we divide 905 by 357, we get 2 and a remainder of 191.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 714 from 905 and we're left with 191.
Fetch the next digit (2) from the dividend, attach it to 191 and continue: 1912 / 357

Advancing to step 4:
357 can be fit into 1912 5 times, resulting in a remainder of 127.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1785 from 1912 to get 127.
Take the next digit (1) from the dividend and append it to 127, then repeat: 1271 / 357

Moving on to step 5:
If we divide 1271 by 357, we get 3 and a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 253.0
Subtract 1071 from 1271 to get 200.
Append the next digit (4) from the dividend to 200 and continue with: 2004 / 357

Advancing to step 6:
The number 357 fits into 2004 5 times, leaving a remainder of 219.
The number 5 becomes the next digit in our result. 
Result so far: 2535.0
The remainder is 219 after subtracting 1785 from 2004.
Include the next digit (1) from the dividend after 219, then repeat: 2191 / 357

Going ahead to step 7:
If we divide 2191 by 357, we get 6 and a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 25356.0
The remainder is 49 after subtracting 2142 from 2191.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 357

Going ahead to step 8:
357 can be fit into 493 1 times, resulting in a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 253561.0
Subtract 357 from 493 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 9:
357 goes into 1360 3 times with a remainder of 289.
The number 3 becomes the next digit in our result. 
Result so far: 253561.3
The remainder is 289 after subtracting 1071 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
2890 divided by 357 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 253561.38
Subtract 2856 from 2890 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
340 divided by 357 is 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 253561.38
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
357 goes into 3400 9 times with a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 253561.3809
If we subtract 3213 from 3400, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 13:
1870 divided by 357 is 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 253561.38095
Subtract 1785 from 1870 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 14:
357 can be fit into 850 2 times, resulting in a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 253561.380952
If we subtract 714 from 850, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 15:
1360 divided by 357 is 3 with a remainder of 289.
The next digit of our result is 3. 
Result so far: 253561.3809523
The remainder is 289 after subtracting 1071 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 16:
357 can be fit into 2890 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 253561.38095238
The remainder is 34 after subtracting 2856 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 253561.38095238, with a leftover of 3.4e-08.
