We look at the division of 51313648 by 109 
We're looking to find how many times 109 goes into 51313648.

Going ahead to step 1:
If we divide 5 by 109, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 109

Let's proceed to step 2:
109 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 109

Advancing to step 3:
When dividing 513 by 109, we get 4 with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 436 from 513 to get 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 109

On to step 4:
109 can be fit into 771 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 763 from 771 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 109

Going ahead to step 5:
The number 109 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 470.0
If we subtract 0 from 83, we get 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 109

On to step 6:
109 can be fit into 836 7 times, resulting in a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 4707.0
The remainder is 73 after subtracting 763 from 836.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 109

Going ahead to step 7:
109 goes into 734 6 times with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 47076.0
Subtract 654 from 734 to get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 109

On to step 8:
808 divided by 109 is 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 470767.0
Subtracting 763 from 808 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
109 goes into 450 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 470767.4
Deduct 436 from 450 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 109 fits into 140 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 470767.41
The remainder is 31 after subtracting 109 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
109 goes into 310 2 times with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 470767.412
Subtracting 218 from 310 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
109 goes into 920 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 470767.4128
Deduct 872 from 920 and we're left 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.

Let's proceed to step 13:
480 divided by 109 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 470767.41284
If we take 436 away from 480, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
When dividing 440 by 109, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 470767.412844
Deduct 436 from 440 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 470767.412844 with a balance of 4e-07.
