We look at the division of 42990284 by 110 
Let's see how many times 110 fits into 42990284.

Going ahead to step 1:
4 divided by 110 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 110

Going ahead to step 2:
When dividing 42 by 110, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 110

Going ahead to step 3:
If we divide 429 by 110, we get 3 and a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 330 from 429, we get 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 110

Let's proceed to step 4:
110 goes into 999 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 990 away from 999, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 110

Going ahead to step 5:
When dividing 90 by 110, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 390.0
If we subtract 0 from 90, we get 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 110

Going ahead to step 6:
When dividing 902 by 110, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 3908.0
Deduct 880 from 902 and we're left with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 110

Going ahead to step 7:
110 goes into 228 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 39082.0
Subtract 220 from 228 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 110

Let's proceed to step 8:
The number 110 fits into 84 0 times, leaving a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 390820.0
Subtracting 0 from 84 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.

On to step 9:
840 divided by 110 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 390820.7
If we take 770 away from 840, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 110 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 390820.76
If we subtract 660 from 700, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
110 can be fit into 400 3 times, resulting in a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 390820.763
Deduct 330 from 400 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
110 goes into 700 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 390820.7636
If we subtract 660 from 700, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 110 is 3 with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 390820.76363
Subtracting 330 from 400 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
The number 110 fits into 700 6 times, leaving a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 390820.763636
The remainder is 40 after subtracting 660 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
400 divided by 110 is 3 with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 390820.7636363
Deduct 330 from 400 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
110 can be fit into 700 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 390820.76363636
Deduct 660 from 700 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 390820.76363636 with a remainder of 4e-08.
