42488 divided by 31 
Our goal is to divide 42488 by 31.

Step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 31

Let's proceed to step 2:
If we divide 42 by 31, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 31 away from 42, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 31

On to step 3:
When dividing 114 by 31, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 93 from 114 leaves us with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 31

Going ahead to step 4:
When dividing 218 by 31, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 217 away from 218, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 31

On to step 5:
When dividing 18 by 31, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 1370.0
Deduct 0 from 18 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 6:
If we divide 180 by 31, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1370.5
If we take 155 away from 180, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 31, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1370.58
If we subtract 248 from 250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 31 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1370.58
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 31 fits into 200 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 1370.5806
If we take 186 away from 200, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
When dividing 140 by 31, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1370.58064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 31, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1370.580645
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1370.5806451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
If we divide 190 by 31, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1370.58064516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 1370.58064516 with a remainder of 4e-09.
