We're dividing 21849871 by 124 
We want to figure out the number of times 21849871 can be divided by 124.

Going ahead to step 1:
124 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 124

Step 2:
When dividing 21 by 124, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 124

Moving on to step 3:
218 divided by 124 is 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 124 from 218 to get 94.
Bring next digit (4) of the dividend behind the 94 and repeat the process: 944 / 124

Moving on to step 4:
124 can be fit into 944 7 times, resulting in a remainder of 76.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 868 from 944, we get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 124

Let's proceed to step 5:
769 divided by 124 is 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Subtracting 744 from 769 leaves us with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 124

Moving on to step 6:
258 divided by 124 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 1762.0
If we subtract 248 from 258, we get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 124

Let's proceed to step 7:
When dividing 107 by 124, we get 0 with a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 17620.0
The remainder is 107 after subtracting 0 from 107.
Take the next digit (1) from the dividend and append it to 107, then repeat: 1071 / 124

Let's proceed to step 8:
When dividing 1071 by 124, we get 8 with a remainder of 79.
The next digit of our result is 8. 
Result so far: 176208.0
The remainder is 79 after subtracting 992 from 1071.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
If we divide 790 by 124, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 176208.6
The remainder is 46 after subtracting 744 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
If we divide 460 by 124, we get 3 and a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 176208.63
The remainder is 88 after subtracting 372 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
880 divided by 124 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 176208.637
Deduct 868 from 880 and we're left 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.

On to step 12:
If we divide 120 by 124, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 176208.637
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
If we divide 1200 by 124, we get 9 and a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 176208.63709
Deduct 1116 from 1200 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
840 divided by 124 is 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 176208.637096
If we take 744 away from 840, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
124 can be fit into 960 7 times, resulting in a remainder of 92.
Record the quotient 7 as the next digit in the result. 
Result so far: 176208.6370967
The remainder is 92 after subtracting 868 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 16:
124 goes into 920 7 times with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 176208.63709677
If we subtract 868 from 920, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 176208.63709677 with a remainder of 5.2e-08.
