We're dividing 21216092 by 239 
We're looking to find how many times 239 goes into 21216092.

Going ahead to step 1:
When dividing 2 by 239, we get 0 with 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 239

Moving on to step 2:
If we divide 21 by 239, we get 0 and 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.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 239

Going ahead to step 3:
239 can be fit into 212 0 times, resulting in a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 239

On to step 4:
2121 divided by 239 is 8 with a remainder of 209.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 1912 from 2121, we get 209.
Grab the next digit (6) from the dividend, add it to 209, then carry on: 2096 / 239

Advancing to step 5:
239 can be fit into 2096 8 times, resulting in a remainder of 184.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 1912 from 2096 leaves us with 184.
Take the next digit (0) from the dividend and append it to 184, then repeat: 1840 / 239

Moving on to step 6:
The number 239 fits into 1840 7 times, leaving a remainder of 167.
The next digit of our result is 7. 
Result so far: 887.0
Deduct 1673 from 1840 and we're left with 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 239

Advancing to step 7:
239 goes into 1679 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 8877.0
The remainder is 6 after subtracting 1673 from 1679.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 239

Let's proceed to step 8:
When dividing 62 by 239, we get 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 88770.0
Deduct 0 from 62 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
239 goes into 620 2 times with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 88770.2
The remainder is 142 after subtracting 478 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 10:
239 can be fit into 1420 5 times, resulting in a remainder of 225.
The next digit of our result is 5. 
Result so far: 88770.25
Subtracting 1195 from 1420 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
2250 divided by 239 is 9 with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 88770.259
Subtracting 2151 from 2250 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 12:
239 can be fit into 990 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 88770.2594
Subtracting 956 from 990 leaves us 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.

Advancing to step 13:
239 goes into 340 1 times with a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 88770.25941
If we take 239 away from 340, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 14:
239 can be fit into 1010 4 times, resulting in a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 88770.259414
If we take 956 away from 1010, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 15:
239 can be fit into 540 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 88770.2594142
If we take 478 away from 540, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 16:
If we divide 620 by 239, we get 2 and a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 88770.25941422
Deduct 478 from 620 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The quotient of the division is 88770.25941422, and the remainder is 1.42e-07.
