We look at the division of 51997178 by 109 
We want to figure out the number of times 51997178 can be divided by 109.

Let's proceed to step 1:
The number 109 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 109

Step 2:
If we divide 51 by 109, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 109

Moving on to step 3:
109 can be fit into 519 4 times, resulting in a remainder of 83.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 436 from 519 and we're left with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 109

Step 4:
109 goes into 839 7 times with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 763 from 839 leaves us with 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 109

Going ahead to step 5:
The number 109 fits into 767 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Subtract 763 from 767 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 109

Going ahead to step 6:
If we divide 41 by 109, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 4770.0
The remainder is 41 after subtracting 0 from 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 109

Let's proceed to step 7:
109 can be fit into 417 3 times, resulting in a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 47703.0
If we subtract 327 from 417, we get 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 109

Moving on to step 8:
109 can be fit into 908 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 477038.0
If we subtract 872 from 908, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 109, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 477038.3
Subtracting 327 from 360 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
109 goes into 330 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 477038.33
Subtract 327 from 330 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 477038.33, and the remainder is 0.003.
