42590334 divided by 503 
We want to divide 42590334 by 503.

Moving on to step 1:
If we divide 4 by 503, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 503

Going ahead to step 2:
If we divide 42 by 503, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 503

Moving on to step 3:
The number 503 fits into 425 0 times, leaving a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Include the next digit (9) from the dividend after 425, then repeat: 4259 / 503

Going ahead to step 4:
The number 503 fits into 4259 8 times, leaving a remainder of 235.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 4024 from 4259 and we're left with 235.
Append the next digit (0) from the dividend to 235 and continue with: 2350 / 503

Advancing to step 5:
503 can be fit into 2350 4 times, resulting in a remainder of 338.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 2012 away from 2350, we end up with 338.
Grab the next digit (3) from the dividend, add it to 338, then carry on: 3383 / 503

Let's proceed to step 6:
The number 503 fits into 3383 6 times, leaving a remainder of 365.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
Deduct 3018 from 3383 and we're left with 365.
Include the next digit (3) from the dividend after 365, then repeat: 3653 / 503

Let's proceed to step 7:
3653 divided by 503 is 7 with a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 8467.0
If we subtract 3521 from 3653, we get 132.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 503

Let's proceed to step 8:
503 can be fit into 1324 2 times, resulting in a remainder of 318.
Write down 2 as next digit of the result. 
Result so far: 84672.0
Deduct 1006 from 1324 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
When dividing 3180 by 503, we get 6 with a remainder of 162.
The number 6 becomes the next digit in our result. 
Result so far: 84672.6
If we take 3018 away from 3180, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 10:
If we divide 1620 by 503, we get 3 and a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 84672.63
The remainder is 111 after subtracting 1509 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 11:
503 can be fit into 1110 2 times, resulting in a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 84672.632
Subtracting 1006 from 1110 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 12:
503 goes into 1040 2 times with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 84672.6322
Deduct 1006 from 1040 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 84672.6322 with a balance of 0.00034.
