We look at the division of 21168538 by 208 
We're looking to find how many times 208 goes into 21168538.

On to step 1:
When dividing 2 by 208, we get 0 with a remainder of 2.
Write down 0 as next digit of 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 / 208

Step 2:
208 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
If we take 0 away from 21, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 208

Step 3:
If we divide 211 by 208, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 208 from 211 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 208

Going ahead to step 4:
36 divided by 208 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 208

Going ahead to step 5:
When dividing 368 by 208, we get 1 with a remainder of 160.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 160 after subtracting 208 from 368.
Grab the next digit (5) from the dividend, add it to 160, then carry on: 1605 / 208

Advancing to step 6:
When dividing 1605 by 208, we get 7 with a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 1017.0
The remainder is 149 after subtracting 1456 from 1605.
Grab the next digit (3) from the dividend, add it to 149, then carry on: 1493 / 208

On to step 7:
When dividing 1493 by 208, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 10177.0
If we subtract 1456 from 1493, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 208

Going ahead to step 8:
378 divided by 208 is 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 101771.0
If we subtract 208 from 378, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
When dividing 1700 by 208, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 101771.8
If we take 1664 away from 1700, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
208 can be fit into 360 1 times, resulting in a remainder of 152.
The next digit of our result is 1. 
Result so far: 101771.81
The remainder is 152 after subtracting 208 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
1520 divided by 208 is 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 101771.817
If we subtract 1456 from 1520, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 208 fits into 640 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 101771.8173
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
If we divide 160 by 208, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 101771.8173
Subtracting 0 from 160 leaves us 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.

On to step 14:
208 can be fit into 1600 7 times, resulting in a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 101771.817307
Subtracting 1456 from 1600 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 15:
When dividing 1440 by 208, we get 6 with a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 101771.8173076
Deduct 1248 from 1440 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 16:
208 goes into 1920 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 101771.81730769
If we take 1872 away from 1920, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 101771.81730769 and a remainder of 4.8e-08.
