21588879 ÷ 748 
Our goal is to divide 21588879 by 748.

Advancing to step 1:
The number 748 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our 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 / 748

Let's proceed to step 2:
748 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 748

Moving on to step 3:
748 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Take the next digit (8) from the dividend and append it to 215, then repeat: 2158 / 748

On to step 4:
748 can be fit into 2158 2 times, resulting in a remainder of 662.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1496 from 2158 leaves us with 662.
Grab the next digit (8) from the dividend, add it to 662, then carry on: 6628 / 748

Moving on to step 5:
If we divide 6628 by 748, we get 8 and a remainder of 644.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 644 after subtracting 5984 from 6628.
Fetch the next digit (8) from the dividend, attach it to 644 and continue: 6448 / 748

Going ahead to step 6:
748 can be fit into 6448 8 times, resulting in a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 288.0
Deduct 5984 from 6448 and we're left with 464.
Grab the next digit (7) from the dividend, add it to 464, then carry on: 4647 / 748

Advancing to step 7:
4647 divided by 748 is 6 with a remainder of 159.
Put 6 as the next digit of the answer. 
Result so far: 2886.0
The remainder is 159 after subtracting 4488 from 4647.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 748

Going ahead to step 8:
When dividing 1599 by 748, we get 2 with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 28862.0
If we take 1496 away from 1599, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
The number 748 fits into 1030 1 times, leaving a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 28862.1
If we take 748 away from 1030, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 10:
2820 divided by 748 is 3 with a remainder of 576.
Write down 3 as next digit of the result. 
Result so far: 28862.13
If we take 2244 away from 2820, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 11:
When dividing 5760 by 748, we get 7 with a remainder of 524.
The next digit of our result is 7. 
Result so far: 28862.137
The remainder is 524 after subtracting 5236 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 12:
748 goes into 5240 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 28862.1377
If we take 5236 away from 5240, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 28862.1377 with a balance of 4e-05.
