We look at the division of 42235990 by 320 
Let's see how many times 320 fits into 42235990.

Moving on to step 1:
4 divided by 320 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 320

Moving on to step 2:
320 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 320

Moving on to step 3:
If we divide 422 by 320, we get 1 and a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 320 from 422 to get 102.
Append the next digit (3) from the dividend to 102 and continue with: 1023 / 320

Let's proceed to step 4:
320 can be fit into 1023 3 times, resulting in a remainder of 63.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 960 from 1023 to get 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 320

Going ahead to step 5:
635 divided by 320 is 1 with a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
The remainder is 315 after subtracting 320 from 635.
Include the next digit (9) from the dividend after 315, then repeat: 3159 / 320

Step 6:
3159 divided by 320 is 9 with a remainder of 279.
Write down 9 as next digit of the result. 
Result so far: 1319.0
Subtract 2880 from 3159 to get 279.
Include the next digit (9) from the dividend after 279, then repeat: 2799 / 320

Advancing to step 7:
320 goes into 2799 8 times with a remainder of 239.
Record the quotient 8 as the next digit in the result. 
Result so far: 13198.0
If we subtract 2560 from 2799, we get 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 320

Let's proceed to step 8:
320 can be fit into 2390 7 times, resulting in a remainder of 150.
The next digit of our result is 7. 
Result so far: 131987.0
Deduct 2240 from 2390 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
1500 divided by 320 is 4 with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 131987.4
If we subtract 1280 from 1500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
The number 320 fits into 2200 6 times, leaving a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 131987.46
Subtracting 1920 from 2200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
When dividing 2800 by 320, we get 8 with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 131987.468
Deduct 2560 from 2800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
The number 320 fits into 2400 7 times, leaving a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 131987.4687
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 131987.46875
Subtracting 1600 from 1600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 320, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 131987.46875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
0 divided by 320 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 131987.46875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 131987.46875, and the remainder is 0.0.
