21168460 ÷ 124 
Our goal is to divide 21168460 by 124.

Advancing to step 1:
When dividing 2 by 124, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 124

Going ahead to step 2:
124 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 124

Going ahead to step 3:
If we divide 211 by 124, we get 1 and a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 124 from 211 leaves us with 87.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 124

Moving on to step 4:
The number 124 fits into 876 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 868 from 876 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 124

Advancing to step 5:
When dividing 88 by 124, we get 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 124

Going ahead to step 6:
124 can be fit into 884 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 1707.0
If we subtract 868 from 884, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 124

Advancing to step 7:
166 divided by 124 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 17071.0
Subtract 124 from 166 to get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 124

Let's proceed to step 8:
When dividing 420 by 124, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 170713.0
Subtract 372 from 420 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
124 can be fit into 480 3 times, resulting in a remainder of 108.
The next digit of our result is 3. 
Result so far: 170713.3
If we subtract 372 from 480, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 10:
When dividing 1080 by 124, we get 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 170713.38
Subtract 992 from 1080 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
The number 124 fits into 880 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 170713.387
The remainder is 12 after subtracting 868 from 880.
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 12:
When dividing 120 by 124, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 170713.387
If we take 0 away from 120, we end up 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.

Let's proceed to step 13:
124 goes into 1200 9 times with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 170713.38709
The remainder is 84 after subtracting 1116 from 1200.
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:
124 can be fit into 840 6 times, resulting in a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 170713.387096
Subtracting 744 from 840 leaves us 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.

Going ahead to step 15:
960 divided by 124 is 7 with a remainder of 92.
The next digit of our result is 7. 
Result so far: 170713.3870967
If we take 868 away from 960, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 16:
The number 124 fits into 920 7 times, leaving a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 170713.38709677
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.

Our division results in 170713.38709677 with a remaining 5.2e-08.
