835 divided by 242 is 3 with a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Deduct 726 from 835 and we're left with 109.
Take the next digit (2) from the dividend and append it to 109, then repeat: 1092 / 242

Moving on to step 6:
When dividing 1092 by 242, we get 4 with a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 3734.0
If we subtract 968 from 1092, we get 124.
Bring next digit (2) of the dividend behind the 124 and repeat the process: 1242 / 242

Advancing to step 7:
1242 divided by 242 is 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 37345.0
The remainder is 32 after subtracting 1210 from 1242.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 242

Moving on to step 8:
When dividing 325 by 242, we get 1 with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 373451.0
Deduct 242 from 325 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
242 can be fit into 830 3 times, resulting in a remainder of 104.
Put 3 as the next digit of the answer. 
Result so far: 373451.3
The remainder is 104 after subtracting 726 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
When dividing 1040 by 242, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 373451.34
The remainder is 72 after subtracting 968 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
242 can be fit into 720 2 times, resulting in a remainder of 236.
The next digit of our result is 2. 
Result so far: 373451.342
If we take 484 away from 720, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 12:
242 goes into 2360 9 times with a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 373451.3429
If we subtract 2178 from 2360, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 13:
1820 divided by 242 is 7 with a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 373451.34297
If we take 1694 away from 1820, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 14:
242 goes into 1260 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 373451.342975
Subtracting 1210 from 1260 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
242 can be fit into 500 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 373451.3429752
If we take 484 away from 500, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
When dividing 160 by 242, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 373451.3429752
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 373451.3429752 with a remaining 1.6e-07.
