42085569 ÷ 549 
We want to figure out the number of times 42085569 can be divided by 549.

On to step 1:
If we divide 4 by 549, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 549

Step 2:
42 divided by 549 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 549

Advancing to step 3:
549 can be fit into 420 0 times, resulting in a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Include the next digit (8) from the dividend after 420, then repeat: 4208 / 549

Step 4:
The number 549 fits into 4208 7 times, leaving a remainder of 365.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 3843 from 4208 to get 365.
Append the next digit (5) from the dividend to 365 and continue with: 3655 / 549

Step 5:
3655 divided by 549 is 6 with a remainder of 361.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 3294 from 3655 and we're left with 361.
Take the next digit (5) from the dividend and append it to 361, then repeat: 3615 / 549

Advancing to step 6:
549 goes into 3615 6 times with a remainder of 321.
Put 6 as the next digit of the answer. 
Result so far: 766.0
The remainder is 321 after subtracting 3294 from 3615.
Take the next digit (6) from the dividend and append it to 321, then repeat: 3216 / 549

Let's proceed to step 7:
When dividing 3216 by 549, we get 5 with a remainder of 471.
The next digit of our result is 5. 
Result so far: 7665.0
If we take 2745 away from 3216, we end up with 471.
Take the next digit (9) from the dividend and append it to 471, then repeat: 4719 / 549

Step 8:
4719 divided by 549 is 8 with a remainder of 327.
Use 8 as the next digit of our solution. 
Result so far: 76658.0
If we subtract 4392 from 4719, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
3270 divided by 549 is 5 with a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 76658.5
The remainder is 525 after subtracting 2745 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 10:
5250 divided by 549 is 9 with a remainder of 309.
The next digit of our result is 9. 
Result so far: 76658.59
The remainder is 309 after subtracting 4941 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 11:
If we divide 3090 by 549, we get 5 and a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 76658.595
Subtract 2745 from 3090 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 12:
The number 549 fits into 3450 6 times, leaving a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 76658.5956
If we take 3294 away from 3450, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
549 goes into 1560 2 times with a remainder of 462.
Use 2 as the next digit of our solution. 
Result so far: 76658.59562
Deduct 1098 from 1560 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 14:
549 can be fit into 4620 8 times, resulting in a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 76658.595628
Deduct 4392 from 4620 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 15:
2280 divided by 549 is 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 76658.5956284
Subtracting 2196 from 2280 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 16:
When dividing 840 by 549, we get 1 with a remainder of 291.
The next digit of our result is 1. 
Result so far: 76658.59562841
If we take 549 away from 840, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

In conclusion, the division gives 76658.59562841 with a balance of 2.91e-07.
