We divide 425243 by 31
We want to divide 425243 by 31.

Going ahead to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 31

Let's proceed to step 2:
When dividing 42 by 31, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 31 from 42 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 31

Advancing to step 3:
When dividing 115 by 31, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 93 from 115 leaves us with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 31

Advancing to step 4:
31 can be fit into 222 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtracting 217 from 222 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 31

Let's proceed to step 5:
If we divide 54 by 31, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1371.0
Subtract 31 from 54 to get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 31

Advancing to step 6:
31 goes into 233 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 13717.0
Subtract 217 from 233 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.

Moving on to step 7:
31 goes into 160 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13717.5
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 31, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 13717.51
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
190 divided by 31 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13717.516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 31 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 13717.5161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 13717.51612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13717.516129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
10 divided by 31 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13717.516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13717.51612903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 13717.51612903 and a remainder of 7e-09.
