We look at the division of 102377 by 31 
Let's see how many times 31 fits into 102377.

Step 1:
31 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 31

Going ahead to step 2:
10 divided by 31 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 31

Step 3:
31 can be fit into 102 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 93 away from 102, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 31

Going ahead to step 4:
93 divided by 31 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 0 after subtracting 93 from 93.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 31

On to step 5:
If we divide 7 by 31, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 31

Moving on to step 6:
77 divided by 31 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 3302.0
If we subtract 62 from 77, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 3302.4
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 31, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3302.48
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 31, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3302.483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 3302.4838
Deduct 248 from 270 and we're left 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.

Moving on to step 11:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3302.48387
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
When dividing 30 by 31, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3302.48387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
The number 31 fits into 300 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 3302.4838709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
If we divide 210 by 31, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3302.48387096
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 3302.48387096, with a leftover of 2.4e-08.
