23879490 ÷ 49 
We want to figure out the number of times 23879490 can be divided by 49.

On to step 1:
When dividing 2 by 49, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 49

On to step 2:
If we divide 23 by 49, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 49

Step 3:
When dividing 238 by 49, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 196 away from 238, we end up with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 49

Moving on to step 4:
If we divide 427 by 49, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 392 away from 427, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 49

Let's proceed to step 5:
359 divided by 49 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 487.0
Subtract 343 from 359 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 49

Advancing to step 6:
49 goes into 164 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4873.0
Subtracting 147 from 164 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 49

On to step 7:
When dividing 179 by 49, we get 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 48733.0
If we subtract 147 from 179, we get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 49

Let's proceed to step 8:
When dividing 320 by 49, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 487336.0
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 49, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 487336.5
The remainder is 15 after subtracting 245 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
49 goes into 150 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 487336.53
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 487336.53
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
49 goes into 300 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 487336.5306
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
If we divide 60 by 49, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 487336.53061
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
The number 49 fits into 110 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 487336.530612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 15:
When dividing 120 by 49, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 487336.5306122
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 487336.5306122 with a balance of 2.2e-07.
