We divide 21145363 by 208
Our goal is to divide 21145363 by 208.

Going ahead to step 1:
2 divided by 208 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 208

On to step 2:
208 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 208

On to step 3:
When dividing 211 by 208, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 208 away from 211, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 208

Let's proceed to step 4:
208 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 208

Moving on to step 5:
The number 208 fits into 345 1 times, leaving a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
The remainder is 137 after subtracting 208 from 345.
Bring next digit (3) of the dividend behind the 137 and repeat the process: 1373 / 208

On to step 6:
208 goes into 1373 6 times with a remainder of 125.
The number 6 becomes the next digit in our result. 
Result so far: 1016.0
Subtract 1248 from 1373 to get 125.
Grab the next digit (6) from the dividend, add it to 125, then carry on: 1256 / 208

Let's proceed to step 7:
208 goes into 1256 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10166.0
If we subtract 1248 from 1256, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 208

Step 8:
208 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 101660.0
If we take 0 away from 83, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
830 divided by 208 is 3 with a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 101660.3
Deduct 624 from 830 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 10:
2060 divided by 208 is 9 with a remainder of 188.
The number 9 becomes the next digit in our result. 
Result so far: 101660.39
Subtracting 1872 from 2060 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
If we divide 1880 by 208, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 101660.399
Subtract 1872 from 1880 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 101660.399 and a remainder of 0.0008.
