51517422 ÷ 108 
We want to figure out the number of times 51517422 can be divided by 108.

Step 1:
If we divide 5 by 108, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 108

Moving on to step 2:
The number 108 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 108

On to step 3:
The number 108 fits into 515 4 times, leaving a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 432 from 515 to get 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 108

Moving on to step 4:
108 can be fit into 831 7 times, resulting in a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 75 after subtracting 756 from 831.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 108

Going ahead to step 5:
When dividing 757 by 108, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 477.0
If we take 756 away from 757, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 108

Let's proceed to step 6:
If we divide 14 by 108, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 4770.0
Subtract 0 from 14 to get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 108

Step 7:
142 divided by 108 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 47701.0
Subtracting 108 from 142 leaves us with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 108

Moving on to step 8:
108 goes into 342 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 477013.0
Subtract 324 from 342 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 108, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 477013.1
If we take 108 away from 180, we end up 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 10:
720 divided by 108 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 477013.16
If we take 648 away from 720, we end up 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.

On to step 11:
108 can be fit into 720 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 477013.166
Subtracting 648 from 720 leaves us 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.

The final result is 477013.166 with a remainder of 0.0072.
