We look at the division of 31990339 by 242 
Our goal is to divide 31990339 by 242.

Let's proceed to step 1:
When dividing 3 by 242, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 242

On to step 2:
The number 242 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 242

Going ahead to step 3:
When dividing 319 by 242, we get 1 with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 242 away from 319, we end up with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 242

Advancing to step 4:
If we divide 779 by 242, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 726 from 779 to get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 242

Going ahead to step 5:
530 divided by 242 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 132.0
The remainder is 46 after subtracting 484 from 530.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 242

Going ahead to step 6:
The number 242 fits into 463 1 times, leaving a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 1321.0
The remainder is 221 after subtracting 242 from 463.
Include the next digit (3) from the dividend after 221, then repeat: 2213 / 242

Step 7:
The number 242 fits into 2213 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 13219.0
Subtract 2178 from 2213 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 242

On to step 8:
When dividing 359 by 242, we get 1 with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 132191.0
Deduct 242 from 359 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
242 can be fit into 1170 4 times, resulting in a remainder of 202.
Put 4 as the next digit of the answer. 
Result so far: 132191.4
Subtract 968 from 1170 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
242 can be fit into 2020 8 times, resulting in a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 132191.48
If we take 1936 away from 2020, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
The number 242 fits into 840 3 times, leaving a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 132191.483
If we take 726 away from 840, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 12:
If we divide 1140 by 242, we get 4 and a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 132191.4834
If we take 968 away from 1140, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 13:
1720 divided by 242 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 132191.48347
The remainder is 26 after subtracting 1694 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 242 fits into 260 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 132191.483471
Subtract 242 from 260 to 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.

Going ahead to step 15:
If we divide 180 by 242, we get 0 and a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 132191.483471
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
242 can be fit into 1800 7 times, resulting in a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 132191.48347107
If we take 1694 away from 1800, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 132191.48347107 and a remainder of 1.06e-07.
