80042981 ÷ 557 
We want to figure out the number of times 80042981 can be divided by 557.

Advancing to step 1:
The number 557 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 557

Advancing to step 2:
80 divided by 557 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 557

Going ahead to step 3:
557 goes into 800 1 times with a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 243 after subtracting 557 from 800.
Take the next digit (4) from the dividend and append it to 243, then repeat: 2434 / 557

Advancing to step 4:
The number 557 fits into 2434 4 times, leaving a remainder of 206.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2228 from 2434, we get 206.
Grab the next digit (2) from the dividend, add it to 206, then carry on: 2062 / 557

Going ahead to step 5:
2062 divided by 557 is 3 with a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Deduct 1671 from 2062 and we're left with 391.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 557

On to step 6:
557 can be fit into 3919 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1437.0
Deduct 3899 from 3919 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 557

On to step 7:
557 can be fit into 208 0 times, resulting in a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 14370.0
Subtract 0 from 208 to get 208.
Take the next digit (1) from the dividend and append it to 208, then repeat: 2081 / 557

Step 8:
557 can be fit into 2081 3 times, resulting in a remainder of 410.
Write down 3 as next digit of the result. 
Result so far: 143703.0
The remainder is 410 after subtracting 1671 from 2081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 9:
The number 557 fits into 4100 7 times, leaving a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 143703.7
If we take 3899 away from 4100, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 10:
2010 divided by 557 is 3 with a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 143703.73
If we take 1671 away from 2010, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 11:
557 can be fit into 3390 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 143703.736
Deduct 3342 from 3390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
The number 557 fits into 480 0 times, leaving a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 143703.736
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
When dividing 4800 by 557, we get 8 with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 143703.73608
Subtract 4456 from 4800 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 14:
557 can be fit into 3440 6 times, resulting in a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 143703.736086
Subtracting 3342 from 3440 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 15:
557 can be fit into 980 1 times, resulting in a remainder of 423.
The next digit of our result is 1. 
Result so far: 143703.7360861
Deduct 557 from 980 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 16:
4230 divided by 557 is 7 with a remainder of 331.
Write down 7 as next digit of the result. 
Result so far: 143703.73608617
The remainder is 331 after subtracting 3899 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Our division results in 143703.73608617 with a remaining 3.31e-07.
