We look at the division of 21221041 by 39 
Let's see how many times 39 fits into 21221041.

Moving on to step 1:
2 divided by 39 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 39

Moving on to step 2:
39 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 39

Step 3:
The number 39 fits into 212 5 times, leaving a remainder of 17.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 17 after subtracting 195 from 212.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 39

Going ahead to step 4:
When dividing 172 by 39, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 156 from 172 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 39

Going ahead to step 5:
161 divided by 39 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 544.0
If we subtract 156 from 161, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 39

Let's proceed to step 6:
39 goes into 50 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 5441.0
If we take 39 away from 50, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 39

Let's proceed to step 7:
The number 39 fits into 114 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 54412.0
Deduct 78 from 114 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 39

On to step 8:
39 goes into 361 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 544129.0
Subtracting 351 from 361 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 39 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 544129.2
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
When dividing 220 by 39, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 544129.25
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
39 goes into 250 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 544129.256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 39 fits into 160 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 544129.2564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 544129.25641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
10 divided by 39 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 544129.25641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 544129.2564102
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 544129.25641025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 544129.25641025, and the remainder is 2.5e-08.
