21355378 divided by 749 
Let's see how many times 749 fits into 21355378.

Step 1:
If we divide 2 by 749, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 749

Going ahead to step 2:
749 can be fit into 21 0 times, resulting in 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 (3) from the dividend after 21, then repeat: 213 / 749

Going ahead to step 3:
749 can be fit into 213 0 times, resulting in a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Take the next digit (5) from the dividend and append it to 213, then repeat: 2135 / 749

Step 4:
When dividing 2135 by 749, we get 2 with a remainder of 637.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1498 from 2135 and we're left with 637.
Take the next digit (5) from the dividend and append it to 637, then repeat: 6375 / 749

On to step 5:
The number 749 fits into 6375 8 times, leaving a remainder of 383.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 5992 away from 6375, we end up with 383.
Bring next digit (3) of the dividend behind the 383 and repeat the process: 3833 / 749

Moving on to step 6:
749 goes into 3833 5 times with a remainder of 88.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
If we take 3745 away from 3833, we end up with 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 749

Advancing to step 7:
887 divided by 749 is 1 with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 2851.0
Subtracting 749 from 887 leaves us with 138.
Bring next digit (8) of the dividend behind the 138 and repeat the process: 1388 / 749

Going ahead to step 8:
749 can be fit into 1388 1 times, resulting in a remainder of 639.
Put 1 as the next digit of the answer. 
Result so far: 28511.0
If we take 749 away from 1388, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 9:
When dividing 6390 by 749, we get 8 with a remainder of 398.
Use 8 as the next digit of our solution. 
Result so far: 28511.8
The remainder is 398 after subtracting 5992 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 10:
The number 749 fits into 3980 5 times, leaving a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 28511.85
If we subtract 3745 from 3980, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 11:
749 can be fit into 2350 3 times, resulting in a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 28511.853
If we take 2247 away from 2350, 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.

Moving on to step 12:
When dividing 1030 by 749, we get 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 28511.8531
If we take 749 away from 1030, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 13:
2810 divided by 749 is 3 with a remainder of 563.
Write down 3 as next digit of the result. 
Result so far: 28511.85313
The remainder is 563 after subtracting 2247 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Step 14:
749 goes into 5630 7 times with a remainder of 387.
The next digit of our result is 7. 
Result so far: 28511.853137
Subtracting 5243 from 5630 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 15:
749 can be fit into 3870 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 28511.8531375
The remainder is 125 after subtracting 3745 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 16:
If we divide 1250 by 749, we get 1 and a remainder of 501.
The number 1 becomes the next digit in our result. 
Result so far: 28511.85313751
Subtract 749 from 1250 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Our division results in 28511.85313751 with a remaining 5.01e-07.
