We look at the division of 13215420 by 549 
We're looking to find how many times 549 goes into 13215420.

Advancing to step 1:
If we divide 1 by 549, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 549

Advancing to step 2:
The number 549 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 549

Let's proceed to step 3:
549 goes into 132 0 times with a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 132 to get 132.
Include the next digit (1) from the dividend after 132, then repeat: 1321 / 549

Advancing to step 4:
The number 549 fits into 1321 2 times, leaving a remainder of 223.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1098 from 1321 to get 223.
Append the next digit (5) from the dividend to 223 and continue with: 2235 / 549

On to step 5:
549 goes into 2235 4 times with a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 39 after subtracting 2196 from 2235.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 549

Moving on to step 6:
394 divided by 549 is 0 with a remainder of 394.
Use 0 as the next digit of our solution. 
Result so far: 240.0
Deduct 0 from 394 and we're left with 394.
Bring next digit (2) of the dividend behind the 394 and repeat the process: 3942 / 549

Moving on to step 7:
549 can be fit into 3942 7 times, resulting in a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 2407.0
If we subtract 3843 from 3942, we get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 549

Advancing to step 8:
549 can be fit into 990 1 times, resulting in a remainder of 441.
The next digit of our result is 1. 
Result so far: 24071.0
If we take 549 away from 990, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 9:
When dividing 4410 by 549, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 24071.8
Deduct 4392 from 4410 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 549, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 24071.8
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
If we divide 1800 by 549, we get 3 and a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 24071.803
Subtracting 1647 from 1800 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 12:
549 can be fit into 1530 2 times, resulting in a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 24071.8032
The remainder is 432 after subtracting 1098 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 13:
The number 549 fits into 4320 7 times, leaving a remainder of 477.
Use 7 as the next digit of our solution. 
Result so far: 24071.80327
The remainder is 477 after subtracting 3843 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 14:
The number 549 fits into 4770 8 times, leaving a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 24071.803278
If we subtract 4392 from 4770, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 15:
When dividing 3780 by 549, we get 6 with a remainder of 486.
Record the quotient 6 as the next digit in the result. 
Result so far: 24071.8032786
If we subtract 3294 from 3780, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 16:
If we divide 4860 by 549, we get 8 and a remainder of 468.
Record the quotient 8 as the next digit in the result. 
Result so far: 24071.80327868
If we take 4392 away from 4860, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final result is 24071.80327868 with a remainder of 4.68e-07.
