We divide 42426839 by 31
We want to figure out the number of times 42426839 can be divided by 31.

Let's proceed to step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 31

Going ahead to step 2:
31 can be fit into 42 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 31 from 42, we get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 31

Step 3:
31 can be fit into 114 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 93 away from 114, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 31

Advancing to step 4:
If we divide 212 by 31, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 186 from 212, we get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 31

Step 5:
If we divide 266 by 31, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Deduct 248 from 266 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 31

Moving on to step 6:
188 divided by 31 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 13686.0
Subtracting 186 from 188 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 31

Going ahead to step 7:
31 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 136860.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 31

Going ahead to step 8:
31 can be fit into 239 7 times, resulting in a remainder of 22.
The next digit of our result is 7. 
Result so far: 1368607.0
If we take 217 away from 239, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
31 goes into 220 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1368607.7
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1368607.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
If we divide 300 by 31, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1368607.709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1368607.7096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 1368607.70967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
If we divide 230 by 31, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1368607.709677
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 1368607.709677 and a remainder of 1.3e-06.
