We divide 21009901 by 541
We want to figure out the number of times 21009901 can be divided by 541.

Moving on to step 1:
If we divide 2 by 541, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 541

Let's proceed to step 2:
When dividing 21 by 541, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 541

Moving on to step 3:
The number 541 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 541

Going ahead to step 4:
The number 541 fits into 2100 3 times, leaving a remainder of 477.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1623 from 2100 leaves us with 477.
Take the next digit (9) from the dividend and append it to 477, then repeat: 4779 / 541

Moving on to step 5:
If we divide 4779 by 541, we get 8 and a remainder of 451.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 4328 from 4779 leaves us with 451.
Take the next digit (9) from the dividend and append it to 451, then repeat: 4519 / 541

Step 6:
541 goes into 4519 8 times with a remainder of 191.
Write down 8 as next digit of the result. 
Result so far: 388.0
Subtract 4328 from 4519 to get 191.
Grab the next digit (0) from the dividend, add it to 191, then carry on: 1910 / 541

Moving on to step 7:
If we divide 1910 by 541, we get 3 and a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 3883.0
Subtract 1623 from 1910 to get 287.
Append the next digit (1) from the dividend to 287 and continue with: 2871 / 541

Let's proceed to step 8:
541 can be fit into 2871 5 times, resulting in a remainder of 166.
The next digit of our result is 5. 
Result so far: 38835.0
Deduct 2705 from 2871 and we're left with 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 9:
When dividing 1660 by 541, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 38835.3
The remainder is 37 after subtracting 1623 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
The number 541 fits into 370 0 times, leaving a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 38835.3
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
The number 541 fits into 3700 6 times, leaving a remainder of 454.
The next digit of our result is 6. 
Result so far: 38835.306
Subtracting 3246 from 3700 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 12:
541 can be fit into 4540 8 times, resulting in a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 38835.3068
Subtracting 4328 from 4540 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
When dividing 2120 by 541, we get 3 with a remainder of 497.
Record the quotient 3 as the next digit in the result. 
Result so far: 38835.30683
If we take 1623 away from 2120, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 14:
If we divide 4970 by 541, we get 9 and a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 38835.306839
Subtracting 4869 from 4970 leaves us 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.

On to step 15:
1010 divided by 541 is 1 with a remainder of 469.
Record the quotient 1 as the next digit in the result. 
Result so far: 38835.3068391
Subtracting 541 from 1010 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

On to step 16:
The number 541 fits into 4690 8 times, leaving a remainder of 362.
Use 8 as the next digit of our solution. 
Result so far: 38835.30683918
Subtract 4328 from 4690 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The quotient of the division is 38835.30683918, and the remainder is 3.62e-07.
