We look at the division of 42565100 by 310 
We want to divide 42565100 by 310.

Going ahead to step 1:
When dividing 4 by 310, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 310

Going ahead to step 2:
42 divided by 310 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 310

Moving on to step 3:
310 goes into 425 1 times with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 310 from 425 and we're left with 115.
Append the next digit (6) from the dividend to 115 and continue with: 1156 / 310

Let's proceed to step 4:
If we divide 1156 by 310, we get 3 and a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 930 from 1156 and we're left with 226.
Grab the next digit (5) from the dividend, add it to 226, then carry on: 2265 / 310

Let's proceed to step 5:
2265 divided by 310 is 7 with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 2170 from 2265 to get 95.
Append the next digit (1) from the dividend to 95 and continue with: 951 / 310

On to step 6:
310 can be fit into 951 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 1373.0
The remainder is 21 after subtracting 930 from 951.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 310

On to step 7:
310 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 13730.0
Subtract 0 from 210 to get 210.
Fetch the next digit (0) from the dividend, attach it to 210 and continue: 2100 / 310

Moving on to step 8:
The number 310 fits into 2100 6 times, leaving a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 137306.0
Deduct 1860 from 2100 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.

On to step 9:
2400 divided by 310 is 7 with a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 137306.7
Deduct 2170 from 2400 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
If we divide 2300 by 310, we get 7 and a remainder of 130.
The next digit of our result is 7. 
Result so far: 137306.77
If we subtract 2170 from 2300, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 137306.77 with a remainder of 0.13.
