We look at the division of 340390 by 49 
We want to figure out the number of times 340390 can be divided by 49.

On to step 1:
When dividing 3 by 49, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 49

Let's proceed to step 2:
The number 49 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 49

On to step 3:
49 can be fit into 340 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 294 from 340, we get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 49

Moving on to step 4:
When dividing 463 by 49, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 69.0
If we subtract 441 from 463, we get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 49

Moving on to step 5:
When dividing 229 by 49, we get 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 694.0
If we subtract 196 from 229, we get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 49

Moving on to step 6:
The number 49 fits into 330 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6946.0
Subtract 294 from 330 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6946.7
If we take 343 away from 360, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
49 goes into 170 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 6946.73
Subtract 147 from 170 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
The number 49 fits into 230 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 6946.734
Subtracting 196 from 230 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 49, we get 6 and a remainder of 46.
The next digit of our result is 6. 
Result so far: 6946.7346
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
The number 49 fits into 460 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 6946.73469
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
49 can be fit into 190 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 6946.734693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
49 goes into 430 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 6946.7346938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
49 goes into 380 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 6946.73469387
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 6946.73469387 and a remainder of 3.7e-08.
