Let's divide 42521314 by 290
Our goal is to divide 42521314 by 290.

Advancing to step 1:
290 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 290

Advancing to step 2:
290 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
If we subtract 0 from 42, we get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 290

Advancing to step 3:
290 goes into 425 1 times with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 290 from 425, we get 135.
Bring next digit (2) of the dividend behind the 135 and repeat the process: 1352 / 290

Let's proceed to step 4:
290 can be fit into 1352 4 times, resulting in a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1160 from 1352 and we're left with 192.
Append the next digit (1) from the dividend to 192 and continue with: 1921 / 290

Step 5:
If we divide 1921 by 290, we get 6 and a remainder of 181.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtract 1740 from 1921 to get 181.
Include the next digit (3) from the dividend after 181, then repeat: 1813 / 290

Going ahead to step 6:
1813 divided by 290 is 6 with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 1466.0
Deduct 1740 from 1813 and we're left with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 290

Going ahead to step 7:
If we divide 731 by 290, we get 2 and a remainder of 151.
Write down 2 as next digit of the result. 
Result so far: 14662.0
Deduct 580 from 731 and we're left with 151.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 290

On to step 8:
The number 290 fits into 1514 5 times, leaving a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 146625.0
The remainder is 64 after subtracting 1450 from 1514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
If we divide 640 by 290, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 146625.2
If we subtract 580 from 640, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
The number 290 fits into 600 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 146625.22
Subtracting 580 from 600 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 146625.22 with a remainder of 0.02.
