We look at the division of 21965486 by 442 
Let's see how many times 442 fits into 21965486.

On to step 1:
When dividing 2 by 442, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 442

Going ahead to step 2:
21 divided by 442 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 442

Moving on to step 3:
If we divide 219 by 442, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Take the next digit (6) from the dividend and append it to 219, then repeat: 2196 / 442

Let's proceed to step 4:
When dividing 2196 by 442, we get 4 with a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 1768 from 2196, we get 428.
Append the next digit (5) from the dividend to 428 and continue with: 4285 / 442

On to step 5:
4285 divided by 442 is 9 with a remainder of 307.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 3978 from 4285, we get 307.
Fetch the next digit (4) from the dividend, attach it to 307 and continue: 3074 / 442

Moving on to step 6:
3074 divided by 442 is 6 with a remainder of 422.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
Subtract 2652 from 3074 to get 422.
Bring next digit (8) of the dividend behind the 422 and repeat the process: 4228 / 442

Step 7:
If we divide 4228 by 442, we get 9 and a remainder of 250.
Use 9 as the next digit of our solution. 
Result so far: 4969.0
If we take 3978 away from 4228, we end up with 250.
Grab the next digit (6) from the dividend, add it to 250, then carry on: 2506 / 442

Step 8:
The number 442 fits into 2506 5 times, leaving a remainder of 296.
Use 5 as the next digit of our solution. 
Result so far: 49695.0
Subtracting 2210 from 2506 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 9:
442 can be fit into 2960 6 times, resulting in a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 49695.6
The remainder is 308 after subtracting 2652 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 10:
The number 442 fits into 3080 6 times, leaving a remainder of 428.
Write down 6 as next digit of the result. 
Result so far: 49695.66
Deduct 2652 from 3080 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final result is 49695.66 with a remainder of 0.428.
