21990548 ÷ 457 
Our goal is to divide 21990548 by 457.

Moving on to step 1:
The number 457 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 457

Going ahead to step 2:
If we divide 21 by 457, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 457

Step 3:
The number 457 fits into 219 0 times, leaving a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 457

Advancing to step 4:
457 can be fit into 2199 4 times, resulting in a remainder of 371.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1828 from 2199 and we're left with 371.
Take the next digit (0) from the dividend and append it to 371, then repeat: 3710 / 457

Going ahead to step 5:
3710 divided by 457 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 3656 from 3710 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 457

Let's proceed to step 6:
457 goes into 545 1 times with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 481.0
The remainder is 88 after subtracting 457 from 545.
Fetch the next digit (4) from the dividend, attach it to 88 and continue: 884 / 457

Going ahead to step 7:
When dividing 884 by 457, we get 1 with a remainder of 427.
The next digit of our result is 1. 
Result so far: 4811.0
If we take 457 away from 884, we end up with 427.
Include the next digit (8) from the dividend after 427, then repeat: 4278 / 457

Let's proceed to step 8:
If we divide 4278 by 457, we get 9 and a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 48119.0
Subtract 4113 from 4278 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 9:
457 can be fit into 1650 3 times, resulting in a remainder of 279.
The next digit of our result is 3. 
Result so far: 48119.3
If we take 1371 away from 1650, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 10:
When dividing 2790 by 457, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 48119.36
Subtract 2742 from 2790 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
457 goes into 480 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 48119.361
The remainder is 23 after subtracting 457 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 457, we get 0 and a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 48119.361
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
When dividing 2300 by 457, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 48119.36105
Subtracting 2285 from 2300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
150 divided by 457 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 48119.36105
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
If we divide 1500 by 457, we get 3 and a remainder of 129.
The next digit of our result is 3. 
Result so far: 48119.3610503
Subtract 1371 from 1500 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 16:
457 can be fit into 1290 2 times, resulting in a remainder of 376.
The next digit of our result is 2. 
Result so far: 48119.36105032
The remainder is 376 after subtracting 914 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 48119.36105032, and the remainder is 3.76e-07.
