We're dividing 137199 by 31 
Let's see how many times 31 fits into 137199.

Going ahead to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 31

Going ahead to step 2:
If we divide 13 by 31, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 31

Going ahead to step 3:
When dividing 137 by 31, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 124 from 137 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 31

Let's proceed to step 4:
The number 31 fits into 131 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 124 from 131 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 31

Step 5:
The number 31 fits into 79 2 times, leaving a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
Subtract 62 from 79 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 31

Advancing to step 6:
When dividing 179 by 31, we get 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 4425.0
If we take 155 away from 179, we end up with 24.
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 7:
When dividing 240 by 31, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 4425.7
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.

Moving on to step 8:
31 goes into 230 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 4425.77
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 4425.77 with a remaining 0.013.
