Let's divide 21183622 by 168
We're looking to find how many times 168 goes into 21183622.

Advancing to step 1:
168 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 / 168

Going ahead to step 2:
168 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 168

Step 3:
If we divide 211 by 168, we get 1 and a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 168 from 211 leaves us with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 168

Advancing to step 4:
The number 168 fits into 438 2 times, leaving a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 336 away from 438, we end up with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 168

Advancing to step 5:
168 can be fit into 1023 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
The remainder is 15 after subtracting 1008 from 1023.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 168

Let's proceed to step 6:
The number 168 fits into 156 0 times, leaving a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
The remainder is 156 after subtracting 0 from 156.
Bring next digit (2) of the dividend behind the 156 and repeat the process: 1562 / 168

Moving on to step 7:
If we divide 1562 by 168, we get 9 and a remainder of 50.
The next digit of our result is 9. 
Result so far: 12609.0
Subtract 1512 from 1562 to get 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 168

Advancing to step 8:
If we divide 502 by 168, we get 2 and a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 126092.0
If we subtract 336 from 502, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 9:
If we divide 1660 by 168, we get 9 and a remainder of 148.
The number 9 becomes the next digit in our result. 
Result so far: 126092.9
The remainder is 148 after subtracting 1512 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
168 goes into 1480 8 times with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 126092.98
Subtracting 1344 from 1480 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
When dividing 1360 by 168, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 126092.988
If we subtract 1344 from 1360, we 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.

Our division results in 126092.988 with a remaining 0.0016.
