Let's divide 66320804 by 549
We want to divide 66320804 by 549.

On to step 1:
When dividing 6 by 549, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 549

Going ahead to step 2:
549 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 549

Going ahead to step 3:
The number 549 fits into 663 1 times, leaving a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 114 after subtracting 549 from 663.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 549

Advancing to step 4:
The number 549 fits into 1142 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1098 from 1142, we get 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 549

Step 5:
440 divided by 549 is 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 440, we get 440.
Bring next digit (8) of the dividend behind the 440 and repeat the process: 4408 / 549

Moving on to step 6:
If we divide 4408 by 549, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1208.0
The remainder is 16 after subtracting 4392 from 4408.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 549

Moving on to step 7:
The number 549 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 12080.0
Deduct 0 from 160 and we're left with 160.
Take the next digit (4) from the dividend and append it to 160, then repeat: 1604 / 549

Advancing to step 8:
When dividing 1604 by 549, we get 2 with a remainder of 506.
Write down 2 as next digit of the result. 
Result so far: 120802.0
Subtract 1098 from 1604 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 9:
549 can be fit into 5060 9 times, resulting in a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 120802.9
Deduct 4941 from 5060 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 10:
When dividing 1190 by 549, we get 2 with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 120802.92
The remainder is 92 after subtracting 1098 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
If we divide 920 by 549, we get 1 and a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 120802.921
If we take 549 away from 920, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 12:
549 can be fit into 3710 6 times, resulting in a remainder of 416.
The next digit of our result is 6. 
Result so far: 120802.9216
If we take 3294 away from 3710, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
549 goes into 4160 7 times with a remainder of 317.
The next digit of our result is 7. 
Result so far: 120802.92167
Subtract 3843 from 4160 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 14:
3170 divided by 549 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 120802.921675
If we subtract 2745 from 3170, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 15:
The number 549 fits into 4250 7 times, leaving a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 120802.9216757
If we subtract 3843 from 4250, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 16:
When dividing 4070 by 549, we get 7 with a remainder of 227.
Put 7 as the next digit of the answer. 
Result so far: 120802.92167577
The remainder is 227 after subtracting 3843 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final outcome is 120802.92167577, with a leftover of 2.27e-07.
