Let's divide 51815193 by 208
Let's see how many times 208 fits into 51815193.

Going ahead to step 1:
The number 208 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 208

Moving on to step 2:
When dividing 51 by 208, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 208

Advancing to step 3:
The number 208 fits into 518 2 times, leaving a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 102 after subtracting 416 from 518.
Append the next digit (1) from the dividend to 102 and continue with: 1021 / 208

Moving on to step 4:
When dividing 1021 by 208, we get 4 with a remainder of 189.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 832 from 1021, we get 189.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 208

Going ahead to step 5:
208 can be fit into 1895 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 249.0
Subtract 1872 from 1895 to get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 208

Moving on to step 6:
If we divide 231 by 208, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 2491.0
If we subtract 208 from 231, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 208

Let's proceed to step 7:
If we divide 239 by 208, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 24911.0
Subtract 208 from 239 to get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 208

Let's proceed to step 8:
208 can be fit into 313 1 times, resulting in a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 249111.0
If we subtract 208 from 313, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
The number 208 fits into 1050 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 249111.5
Subtract 1040 from 1050 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 208 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 249111.5
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
If we divide 1000 by 208, we get 4 and a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 249111.504
If we subtract 832 from 1000, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
1680 divided by 208 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 249111.5048
Subtracting 1664 from 1680 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 208, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 249111.5048
If we subtract 0 from 160, we get 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:
The number 208 fits into 1600 7 times, leaving a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 249111.504807
The remainder is 144 after subtracting 1456 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 15:
The number 208 fits into 1440 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 249111.5048076
Subtract 1248 from 1440 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 16:
208 goes into 1920 9 times with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 249111.50480769
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.

In conclusion, the division gives 249111.50480769 with a balance of 4.8e-08.
