402870 ÷ 49 
Let's see how many times 49 fits into 402870.

Moving on to step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 49

On to step 2:
If we divide 40 by 49, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 49

Step 3:
402 divided by 49 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 392 from 402 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 49

On to step 4:
If we divide 108 by 49, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 98 from 108 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 49

On to step 5:
When dividing 107 by 49, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 822.0
Subtracting 98 from 107 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 49

On to step 6:
49 can be fit into 90 1 times, resulting in a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 8221.0
Subtracting 49 from 90 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 49 fits into 410 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8221.8
Deduct 392 from 410 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 49, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 8221.83
If we subtract 147 from 180, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
49 can be fit into 330 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 8221.836
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
360 divided by 49 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 8221.8367
Subtracting 343 from 360 leaves us 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.

On to step 11:
The number 49 fits into 170 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 8221.83673
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.

Moving on to step 12:
When dividing 230 by 49, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 8221.836734
The remainder is 34 after subtracting 196 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
49 can be fit into 340 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 8221.8367346
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
The number 49 fits into 460 9 times, leaving a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 8221.83673469
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.

In conclusion, the division gives 8221.83673469 with a balance of 1.9e-08.
