We're dividing 425848 by 31 
We want to figure out the number of times 425848 can be divided by 31.

Step 1:
4 divided by 31 is 0 with a remainder of 4.
The number 0 becomes the next digit in our 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

On to step 2:
When dividing 42 by 31, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 31 away from 42, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 31

Step 3:
If we divide 115 by 31, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 93 away from 115, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 31

Going ahead to step 4:
The number 31 fits into 228 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 137.0
Subtract 217 from 228 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 31

Step 5:
The number 31 fits into 114 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 1373.0
Deduct 93 from 114 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 31

On to step 6:
31 can be fit into 218 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 13737.0
If we take 217 away from 218, we end up 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.

Going ahead to step 7:
31 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13737.0
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.

Going ahead to step 8:
The number 31 fits into 100 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 13737.03
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 13737.032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 13737.0322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 13737.0322 and a remainder of 0.00018.
