121963 divided by 31 
Our goal is to divide 121963 by 31.

On to step 1:
1 divided by 31 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 31

Moving on to step 2:
When dividing 12 by 31, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 31

Going ahead to step 3:
121 divided by 31 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 3.0
If we take 93 away from 121, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 31

On to step 4:
If we divide 289 by 31, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 279 from 289 leaves us with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 31

Let's proceed to step 5:
If we divide 106 by 31, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 393.0
If we take 93 away from 106, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 31

Step 6:
If we divide 133 by 31, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 3934.0
The remainder is 9 after subtracting 124 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 31, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 3934.2
Subtract 62 from 90 to get 28.
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 8:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3934.29
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 31 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3934.29
If we subtract 0 from 10, we get 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 10:
When dividing 100 by 31, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3934.2903
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.

Let's proceed to step 11:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3934.29032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 3934.290322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 3934.290322 with a remainder of 1.8e-06.
