We look at the division of 351242 by 49 
We want to figure out the number of times 351242 can be divided by 49.

Let's proceed to step 1:
49 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 49

Let's proceed to step 2:
49 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 49

On to step 3:
351 divided by 49 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 343 from 351 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 49

Moving on to step 4:
49 goes into 82 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 33 after subtracting 49 from 82.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 49

Moving on to step 5:
When dividing 334 by 49, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 716.0
Subtracting 294 from 334 leaves us with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 49

Step 6:
49 can be fit into 402 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 7168.0
Subtract 392 from 402 to 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.

On to step 7:
When dividing 100 by 49, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 7168.2
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 49, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7168.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
49 goes into 200 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 7168.204
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
When dividing 40 by 49, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7168.204
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 49, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 7168.20408
Subtract 392 from 400 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.

Going ahead to step 12:
49 can be fit into 80 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 7168.204081
The remainder is 31 after subtracting 49 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
49 can be fit into 310 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 7168.2040816
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
The number 49 fits into 160 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 7168.20408163
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 7168.20408163 with a remainder of 1.3e-08.
