We're dividing 21048859 by 168 
Let's see how many times 168 fits into 21048859.

Advancing to step 1:
If we divide 2 by 168, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 168

Going ahead to step 2:
The number 168 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 168

On to step 3:
168 can be fit into 210 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 168 from 210, we get 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 168

Let's proceed to step 4:
If we divide 424 by 168, we get 2 and a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 336 away from 424, we end up with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 168

Step 5:
888 divided by 168 is 5 with a remainder of 48.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 840 from 888, we get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 168

On to step 6:
168 can be fit into 488 2 times, resulting in a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 1252.0
Subtract 336 from 488 to get 152.
Grab the next digit (5) from the dividend, add it to 152, then carry on: 1525 / 168

Step 7:
If we divide 1525 by 168, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 12529.0
Subtract 1512 from 1525 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 168

Step 8:
168 goes into 139 0 times with a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 125290.0
Subtracting 0 from 139 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
1390 divided by 168 is 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 125290.8
If we take 1344 away from 1390, we end up with 46.
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:
460 divided by 168 is 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 125290.82
Subtracting 336 from 460 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 11:
168 goes into 1240 7 times with a remainder of 64.
The next digit of our result is 7. 
Result so far: 125290.827
If we take 1176 away from 1240, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
640 divided by 168 is 3 with a remainder of 136.
The next digit of our result is 3. 
Result so far: 125290.8273
Subtract 504 from 640 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
The number 168 fits into 1360 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 125290.82738
Subtract 1344 from 1360 to get 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:
The number 168 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 125290.82738
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
168 goes into 1600 9 times with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 125290.8273809
The remainder is 88 after subtracting 1512 from 1600.
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 16:
880 divided by 168 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 125290.82738095
Subtract 840 from 880 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 125290.82738095 with a balance of 4e-08.
