We divide 21158436 by 208
Our goal is to divide 21158436 by 208.

On to step 1:
2 divided by 208 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 208

On to step 2:
The number 208 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 208

Let's proceed to step 3:
208 goes into 211 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 208 away from 211, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 208

Moving on to step 4:
208 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 35 after subtracting 0 from 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 208

Moving on to step 5:
The number 208 fits into 358 1 times, leaving a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 208 from 358 and we're left with 150.
Include the next digit (4) from the dividend after 150, then repeat: 1504 / 208

On to step 6:
If we divide 1504 by 208, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 1017.0
Deduct 1456 from 1504 and we're left with 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 208

Step 7:
208 goes into 483 2 times with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 10172.0
The remainder is 67 after subtracting 416 from 483.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 208

Going ahead to step 8:
208 goes into 676 3 times with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 101723.0
Deduct 624 from 676 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
208 goes into 520 2 times with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 101723.2
If we subtract 416 from 520, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
If we divide 1040 by 208, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 101723.25
Subtracting 1040 from 1040 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
208 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101723.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
208 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 101723.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 101723.25, with a leftover of 0.0.
