42782189 ÷ 403 
We want to divide 42782189 by 403.

Step 1:
403 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 403

On to step 2:
When dividing 42 by 403, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 403

Let's proceed to step 3:
If we divide 427 by 403, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 403 from 427 to get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 403

Step 4:
403 goes into 248 0 times with a remainder of 248.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 248 to get 248.
Append the next digit (2) from the dividend to 248 and continue with: 2482 / 403

Let's proceed to step 5:
When dividing 2482 by 403, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
The remainder is 64 after subtracting 2418 from 2482.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 403

Moving on to step 6:
641 divided by 403 is 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 1061.0
Subtract 403 from 641 to get 238.
Append the next digit (8) from the dividend to 238 and continue with: 2388 / 403

Advancing to step 7:
2388 divided by 403 is 5 with a remainder of 373.
The next digit of our result is 5. 
Result so far: 10615.0
If we subtract 2015 from 2388, we get 373.
Bring next digit (9) of the dividend behind the 373 and repeat the process: 3739 / 403

Going ahead to step 8:
The number 403 fits into 3739 9 times, leaving a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 106159.0
Subtract 3627 from 3739 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
403 goes into 1120 2 times with a remainder of 314.
Put 2 as the next digit of the answer. 
Result so far: 106159.2
Deduct 806 from 1120 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
3140 divided by 403 is 7 with a remainder of 319.
Write down 7 as next digit of the result. 
Result so far: 106159.27
If we subtract 2821 from 3140, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 11:
403 can be fit into 3190 7 times, resulting in a remainder of 369.
Write down 7 as next digit of the result. 
Result so far: 106159.277
If we subtract 2821 from 3190, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The quotient of the division is 106159.277, and the remainder is 0.0369.
