We look at the division of 21568546 by 49 
We want to figure out the number of times 21568546 can be divided by 49.

Moving on to step 1:
2 divided by 49 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 49

Step 2:
The number 49 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 49

Let's proceed to step 3:
If we divide 215 by 49, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 196 away from 215, we end up with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 49

On to step 4:
49 goes into 196 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 196 from 196 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 49

Moving on to step 5:
8 divided by 49 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 440.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 49

Going ahead to step 6:
49 goes into 85 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4401.0
Subtracting 49 from 85 leaves us with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 49

On to step 7:
When dividing 364 by 49, we get 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 44017.0
Subtract 343 from 364 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 49

Step 8:
If we divide 216 by 49, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 440174.0
Subtract 196 from 216 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.

Moving on to step 9:
49 goes into 200 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 440174.4
If we take 196 away from 200, we end up 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.

Let's proceed to step 10:
49 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 440174.4
Subtracting 0 from 40 leaves us 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.

Advancing to step 11:
49 can be fit into 400 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 440174.408
Subtracting 392 from 400 leaves us with 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:
The number 49 fits into 80 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 440174.4081
Deduct 49 from 80 and we're left with 31.
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:
If we divide 310 by 49, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 440174.40816
Deduct 294 from 310 and we're left 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.

On to step 14:
49 goes into 160 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 440174.408163
If we subtract 147 from 160, we get 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 15:
If we divide 130 by 49, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 440174.4081632
Subtracting 98 from 130 leaves us 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.

Let's proceed to step 16:
49 can be fit into 320 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 440174.40816326
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 440174.40816326 with a remainder of 2.6e-08.
