We're looking to find how many times 49 goes into 21971955.

On to step 1:
2 divided by 49 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 49

Moving on to step 2:
The number 49 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 49

Moving on to step 3:
219 divided by 49 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 196 from 219 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 49

Moving on to step 4:
49 can be fit into 237 4 times, resulting in a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 196 from 237, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 49

Advancing to step 5:
If we divide 411 by 49, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 448.0
If we take 392 away from 411, we end up with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 49

Advancing to step 6:
49 goes into 199 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4484.0
Subtracting 196 from 199 leaves us with 3.

The number 0 becomes the next digit in our result. 
Result so far: 44840.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 49

On to step 8:
If we divide 355 by 49, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 448407.0
If we take 343 away from 355, we end up 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.

Moving on to step 9:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 448407.2
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
220 divided by 49 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 448407.24
If we take 196 away from 220, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 49 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 448407.244
If we subtract 196 from 240, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 448407.244, with a leftover of 0.0044.
