21999408 ÷ 38 
We want to divide 21999408 by 38.

Step 1:
38 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
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 / 38

Advancing to step 2:
The number 38 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
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 / 38

Moving on to step 3:
The number 38 fits into 219 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 5.0
If we take 190 away from 219, we end up with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 38

Moving on to step 4:
If we divide 299 by 38, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 33 after subtracting 266 from 299.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 38

Going ahead to step 5:
38 goes into 339 8 times with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 578.0
If we take 304 away from 339, we end up with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 38

Advancing to step 6:
If we divide 354 by 38, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 5789.0
If we subtract 342 from 354, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 38

On to step 7:
When dividing 120 by 38, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 57893.0
Deduct 114 from 120 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 38

Advancing to step 8:
38 goes into 68 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 578931.0
The remainder is 30 after subtracting 38 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 578931.7
If we take 266 away from 300, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
38 goes into 340 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 578931.78
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
The number 38 fits into 360 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 578931.789
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 38 fits into 180 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 578931.7894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
The number 38 fits into 280 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 578931.78947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
38 can be fit into 140 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 578931.789473
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
When dividing 260 by 38, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 578931.7894736
If we subtract 228 from 260, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
320 divided by 38 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 578931.78947368
If we take 304 away from 320, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 578931.78947368 with a remaining 1.6e-08.
