We're dividing 21290113 by 443 
Let's see how many times 443 fits into 21290113.

Going ahead to step 1:
The number 443 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 443

Let's proceed to step 2:
443 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 443

Advancing to step 3:
When dividing 212 by 443, we get 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Include the next digit (9) from the dividend after 212, then repeat: 2129 / 443

Going ahead to step 4:
443 goes into 2129 4 times with a remainder of 357.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1772 from 2129 to get 357.
Bring next digit (0) of the dividend behind the 357 and repeat the process: 3570 / 443

Going ahead to step 5:
The number 443 fits into 3570 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 3544 from 3570 leaves us with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 443

Moving on to step 6:
If we divide 261 by 443, we get 0 and a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
Subtracting 0 from 261 leaves us with 261.
Take the next digit (1) from the dividend and append it to 261, then repeat: 2611 / 443

Going ahead to step 7:
When dividing 2611 by 443, we get 5 with a remainder of 396.
Record the quotient 5 as the next digit in the result. 
Result so far: 4805.0
If we subtract 2215 from 2611, we get 396.
Bring next digit (3) of the dividend behind the 396 and repeat the process: 3963 / 443

Advancing to step 8:
If we divide 3963 by 443, we get 8 and a remainder of 419.
Use 8 as the next digit of our solution. 
Result so far: 48058.0
Subtract 3544 from 3963 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
If we divide 4190 by 443, we get 9 and a remainder of 203.
Put 9 as the next digit of the answer. 
Result so far: 48058.9
The remainder is 203 after subtracting 3987 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 10:
443 can be fit into 2030 4 times, resulting in a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 48058.94
If we subtract 1772 from 2030, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 11:
When dividing 2580 by 443, we get 5 with a remainder of 365.
The next digit of our result is 5. 
Result so far: 48058.945
If we take 2215 away from 2580, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 12:
443 goes into 3650 8 times with a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 48058.9458
Deduct 3544 from 3650 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
443 goes into 1060 2 times with a remainder of 174.
The next digit of our result is 2. 
Result so far: 48058.94582
If we take 886 away from 1060, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 14:
If we divide 1740 by 443, we get 3 and a remainder of 411.
Record the quotient 3 as the next digit in the result. 
Result so far: 48058.945823
If we subtract 1329 from 1740, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Moving on to step 15:
443 goes into 4110 9 times with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 48058.9458239
Deduct 3987 from 4110 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 16:
If we divide 1230 by 443, we get 2 and a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 48058.94582392
The remainder is 344 after subtracting 886 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 48058.94582392 and a remainder of 3.44e-07.
