21293 ÷ 88 
We're looking to find how many times 88 goes into 21293.

Advancing to step 1:
If we divide 2 by 88, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 88

On to step 2:
If we divide 21 by 88, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 88

On to step 3:
88 goes into 212 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 2.0
If we take 176 away from 212, we end up with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 88

On to step 4:
The number 88 fits into 369 4 times, leaving a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 352 from 369 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 88

Going ahead to step 5:
The number 88 fits into 173 1 times, leaving a remainder of 85.
The next digit of our result is 1. 
Result so far: 241.0
If we take 88 away from 173, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 6:
88 goes into 850 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 241.9
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
The number 88 fits into 580 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 241.96
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
If we divide 520 by 88, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 241.965
The remainder is 80 after subtracting 440 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
When dividing 800 by 88, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 241.9659
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 88 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 241.9659
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
When dividing 800 by 88, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 241.965909
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
The number 88 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 241.965909
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 88 fits into 800 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 241.96590909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 241.96590909, and the remainder is 8e-09.
