We look at the division of 402488 by 49 
We want to figure out the number of times 402488 can be divided by 49.

Going ahead to step 1:
If we divide 4 by 49, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 49

Moving on to step 2:
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: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 49

Step 3:
402 divided by 49 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 392 from 402 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 49

On to step 4:
104 divided by 49 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 98 from 104 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 49

On to step 5:
49 can be fit into 68 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 821.0
If we subtract 49 from 68, we get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 49

On to step 6:
If we divide 198 by 49, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 8214.0
If we take 196 away from 198, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
49 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8214.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
49 goes into 200 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 8214.04
Deduct 196 from 200 and we're left with 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 9:
If we divide 40 by 49, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 8214.04
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.

Step 10:
The number 49 fits into 400 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8214.0408
If we subtract 392 from 400, we 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 11:
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: 8214.04081
If we subtract 49 from 80, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
49 goes into 310 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8214.040816
If we take 294 away from 310, 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.

Advancing to step 13:
49 goes into 160 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 8214.0408163
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.

Advancing to step 14:
When dividing 130 by 49, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 8214.04081632
If we take 98 away from 130, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 8214.04081632 with a balance of 3.2e-08.
