21099279 divided by 208 
We want to figure out the number of times 21099279 can be divided by 208.

Step 1:
208 goes into 2 0 times 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.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 208

Advancing to step 2:
When dividing 21 by 208, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 208

Advancing to step 3:
When dividing 210 by 208, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 208 away from 210, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 208

Advancing to step 4:
208 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 29 to get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 208

Going ahead to step 5:
299 divided by 208 is 1 with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we take 208 away from 299, we end up with 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 208

Going ahead to step 6:
208 goes into 912 4 times with a remainder of 80.
The next digit of our result is 4. 
Result so far: 1014.0
Deduct 832 from 912 and we're left with 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 208

Step 7:
If we divide 807 by 208, we get 3 and a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 10143.0
Subtracting 624 from 807 leaves us with 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 208

Let's proceed to step 8:
If we divide 1839 by 208, we get 8 and a remainder of 175.
Put 8 as the next digit of the answer. 
Result so far: 101438.0
Subtracting 1664 from 1839 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
When dividing 1750 by 208, we get 8 with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 101438.8
If we subtract 1664 from 1750, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
If we divide 860 by 208, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 101438.84
If we subtract 832 from 860, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 208 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 101438.841
Deduct 208 from 280 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
If we divide 720 by 208, we get 3 and a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 101438.8413
Subtracting 624 from 720 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
208 can be fit into 960 4 times, resulting in a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 101438.84134
The remainder is 128 after subtracting 832 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
1280 divided by 208 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 101438.841346
If we take 1248 away from 1280, we end up 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.

Going ahead to step 15:
208 goes into 320 1 times with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 101438.8413461
Subtract 208 from 320 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 16:
1120 divided by 208 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 101438.84134615
Subtract 1040 from 1120 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 101438.84134615 with a remainder of 8e-08.
