Let's divide 51708121 by 555
We want to figure out the number of times 51708121 can be divided by 555.

On to step 1:
555 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
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 / 555

Step 2:
When dividing 51 by 555, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 555

Moving on to step 3:
If we divide 517 by 555, we get 0 and a remainder of 517.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Grab the next digit (0) from the dividend, add it to 517, then carry on: 5170 / 555

Going ahead to step 4:
555 goes into 5170 9 times with a remainder of 175.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 4995 from 5170, we get 175.
Include the next digit (8) from the dividend after 175, then repeat: 1758 / 555

Advancing to step 5:
When dividing 1758 by 555, we get 3 with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 1665 from 1758 and we're left with 93.
Take the next digit (1) from the dividend and append it to 93, then repeat: 931 / 555

Going ahead to step 6:
555 goes into 931 1 times with a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 931.0
Subtract 555 from 931 to get 376.
Bring next digit (2) of the dividend behind the 376 and repeat the process: 3762 / 555

On to step 7:
When dividing 3762 by 555, we get 6 with a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 9316.0
If we subtract 3330 from 3762, we get 432.
Append the next digit (1) from the dividend to 432 and continue with: 4321 / 555

Moving on to step 8:
555 goes into 4321 7 times with a remainder of 436.
Write down 7 as next digit of the result. 
Result so far: 93167.0
If we take 3885 away from 4321, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 9:
The number 555 fits into 4360 7 times, leaving a remainder of 475.
The number 7 becomes the next digit in our result. 
Result so far: 93167.7
Deduct 3885 from 4360 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 10:
555 can be fit into 4750 8 times, resulting in a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 93167.78
Deduct 4440 from 4750 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 11:
If we divide 3100 by 555, we get 5 and a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 93167.785
Deduct 2775 from 3100 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
555 can be fit into 3250 5 times, resulting in a remainder of 475.
The next digit of our result is 5. 
Result so far: 93167.7855
Deduct 2775 from 3250 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

After the division, we end up with 93167.7855 and a remainder of 0.00475.
