42815187 ÷ 557 
Our goal is to divide 42815187 by 557.

Let's proceed to step 1:
The number 557 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 557

Going ahead to step 2:
42 divided by 557 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 557

Moving on to step 3:
When dividing 428 by 557, we get 0 with a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 428 leaves us with 428.
Grab the next digit (1) from the dividend, add it to 428, then carry on: 4281 / 557

Advancing to step 4:
When dividing 4281 by 557, we get 7 with a remainder of 382.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 382 after subtracting 3899 from 4281.
Take the next digit (5) from the dividend and append it to 382, then repeat: 3825 / 557

On to step 5:
If we divide 3825 by 557, we get 6 and a remainder of 483.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 3342 from 3825, we get 483.
Grab the next digit (1) from the dividend, add it to 483, then carry on: 4831 / 557

Let's proceed to step 6:
The number 557 fits into 4831 8 times, leaving a remainder of 375.
The next digit of our result is 8. 
Result so far: 768.0
Subtracting 4456 from 4831 leaves us with 375.
Take the next digit (8) from the dividend and append it to 375, then repeat: 3758 / 557

Let's proceed to step 7:
557 goes into 3758 6 times with a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 7686.0
Subtract 3342 from 3758 to get 416.
Append the next digit (7) from the dividend to 416 and continue with: 4167 / 557

On to step 8:
557 can be fit into 4167 7 times, resulting in a remainder of 268.
Use 7 as the next digit of our solution. 
Result so far: 76867.0
Subtracting 3899 from 4167 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 9:
2680 divided by 557 is 4 with a remainder of 452.
Write down 4 as next digit of the result. 
Result so far: 76867.4
Subtracting 2228 from 2680 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
The number 557 fits into 4520 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 76867.48
Subtracting 4456 from 4520 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 557, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 76867.481
Subtracting 557 from 640 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
The number 557 fits into 830 1 times, leaving a remainder of 273.
The next digit of our result is 1. 
Result so far: 76867.4811
Subtract 557 from 830 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The quotient of the division is 76867.4811, and the remainder is 0.00273.
