We look at the division of 21798167 by 442 
We're looking to find how many times 442 goes into 21798167.

Moving on to step 1:
442 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 442

Going ahead to step 2:
The number 442 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 442

On to step 3:
217 divided by 442 is 0 with a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Append the next digit (9) from the dividend to 217 and continue with: 2179 / 442

Advancing to step 4:
442 goes into 2179 4 times with a remainder of 411.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1768 away from 2179, we end up with 411.
Append the next digit (8) from the dividend to 411 and continue with: 4118 / 442

Let's proceed to step 5:
If we divide 4118 by 442, we get 9 and a remainder of 140.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 3978 from 4118 and we're left with 140.
Include the next digit (1) from the dividend after 140, then repeat: 1401 / 442

Advancing to step 6:
442 goes into 1401 3 times with a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
Subtracting 1326 from 1401 leaves us with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 442

Let's proceed to step 7:
When dividing 756 by 442, we get 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 4931.0
Subtract 442 from 756 to get 314.
Grab the next digit (7) from the dividend, add it to 314, then carry on: 3147 / 442

On to step 8:
If we divide 3147 by 442, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 49317.0
If we take 3094 away from 3147, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
442 can be fit into 530 1 times, resulting in a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 49317.1
Subtracting 442 from 530 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
442 goes into 880 1 times with a remainder of 438.
The number 1 becomes the next digit in our result. 
Result so far: 49317.11
Subtracting 442 from 880 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The quotient of the division is 49317.11, and the remainder is 0.438.
