We look at the division of 21653468 by 168 
We're looking to find how many times 168 goes into 21653468.

Moving on to step 1:
If we divide 2 by 168, we get 0 and 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 168

On to step 2:
168 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 168

Going ahead to step 3:
If we divide 216 by 168, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 168 from 216, we get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 168

Let's proceed to step 4:
168 goes into 485 2 times with a remainder of 149.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 336 from 485, we get 149.
Include the next digit (3) from the dividend after 149, then repeat: 1493 / 168

Moving on to step 5:
168 can be fit into 1493 8 times, resulting in a remainder of 149.
The next digit of our result is 8. 
Result so far: 128.0
If we take 1344 away from 1493, we end up with 149.
Take the next digit (4) from the dividend and append it to 149, then repeat: 1494 / 168

Step 6:
When dividing 1494 by 168, we get 8 with a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 1288.0
Subtracting 1344 from 1494 leaves us with 150.
Take the next digit (6) from the dividend and append it to 150, then repeat: 1506 / 168

Advancing to step 7:
The number 168 fits into 1506 8 times, leaving a remainder of 162.
The next digit of our result is 8. 
Result so far: 12888.0
If we subtract 1344 from 1506, we get 162.
Bring next digit (8) of the dividend behind the 162 and repeat the process: 1628 / 168

Advancing to step 8:
168 can be fit into 1628 9 times, resulting in a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 128889.0
The remainder is 116 after subtracting 1512 from 1628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
If we divide 1160 by 168, we get 6 and a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 128889.6
Deduct 1008 from 1160 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
1520 divided by 168 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 128889.69
Deduct 1512 from 1520 and we're left 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.

Let's proceed to step 11:
168 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 128889.69
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
168 can be fit into 800 4 times, resulting in a remainder of 128.
The next digit of our result is 4. 
Result so far: 128889.6904
The remainder is 128 after subtracting 672 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
The number 168 fits into 1280 7 times, leaving a remainder of 104.
Record the quotient 7 as the next digit in the result. 
Result so far: 128889.69047
Deduct 1176 from 1280 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 14:
If we divide 1040 by 168, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 128889.690476
Subtracting 1008 from 1040 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.

Moving on to step 15:
The number 168 fits into 320 1 times, leaving a remainder of 152.
The next digit of our result is 1. 
Result so far: 128889.6904761
If we subtract 168 from 320, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
The number 168 fits into 1520 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 128889.69047619
The remainder is 8 after subtracting 1512 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 128889.69047619 with a balance of 8e-09.
