21096901 ÷ 381 
We want to divide 21096901 by 381.

Let's proceed to step 1:
381 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 381

Step 2:
When dividing 21 by 381, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 381

Moving on to step 3:
The number 381 fits into 210 0 times, leaving a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Take the next digit (9) from the dividend and append it to 210, then repeat: 2109 / 381

Moving on to step 4:
When dividing 2109 by 381, we get 5 with a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 1905 from 2109, we get 204.
Include the next digit (6) from the dividend after 204, then repeat: 2046 / 381

On to step 5:
381 can be fit into 2046 5 times, resulting in a remainder of 141.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 1905 from 2046 leaves us with 141.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 381

Moving on to step 6:
1419 divided by 381 is 3 with a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 553.0
Subtract 1143 from 1419 to get 276.
Include the next digit (0) from the dividend after 276, then repeat: 2760 / 381

Step 7:
381 goes into 2760 7 times with a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 5537.0
If we subtract 2667 from 2760, we get 93.
Bring next digit (1) of the dividend behind the 93 and repeat the process: 931 / 381

Going ahead to step 8:
381 can be fit into 931 2 times, resulting in a remainder of 169.
Use 2 as the next digit of our solution. 
Result so far: 55372.0
The remainder is 169 after subtracting 762 from 931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
381 goes into 1690 4 times with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 55372.4
Subtract 1524 from 1690 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 10:
If we divide 1660 by 381, we get 4 and a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 55372.44
The remainder is 136 after subtracting 1524 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 55372.44 with a remainder of 0.136.
