We're dividing 51517797 by 384 
We want to figure out the number of times 51517797 can be divided by 384.

Moving on to step 1:
5 divided by 384 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 384

Let's proceed to step 2:
384 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 384

Moving on to step 3:
The number 384 fits into 515 1 times, leaving a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 384 from 515 and we're left with 131.
Include the next digit (1) from the dividend after 131, then repeat: 1311 / 384

Moving on to step 4:
If we divide 1311 by 384, we get 3 and a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1152 from 1311, we get 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 384

Moving on to step 5:
384 goes into 1597 4 times with a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 1536 from 1597 leaves us with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 384

Step 6:
384 goes into 617 1 times with a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 1341.0
If we take 384 away from 617, we end up with 233.
Append the next digit (9) from the dividend to 233 and continue with: 2339 / 384

Moving on to step 7:
If we divide 2339 by 384, we get 6 and a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 13416.0
Subtracting 2304 from 2339 leaves us with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 384

Let's proceed to step 8:
The number 384 fits into 357 0 times, leaving a remainder of 357.
Record the quotient 0 as the next digit in the result. 
Result so far: 134160.0
The remainder is 357 after subtracting 0 from 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 9:
If we divide 3570 by 384, we get 9 and a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 134160.9
Deduct 3456 from 3570 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
The number 384 fits into 1140 2 times, leaving a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 134160.92
Subtracting 768 from 1140 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 11:
3720 divided by 384 is 9 with a remainder of 264.
The number 9 becomes the next digit in our result. 
Result so far: 134160.929
Subtracting 3456 from 3720 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 12:
The number 384 fits into 2640 6 times, leaving a remainder of 336.
The next digit of our result is 6. 
Result so far: 134160.9296
Subtract 2304 from 2640 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 13:
3360 divided by 384 is 8 with a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 134160.92968
If we subtract 3072 from 3360, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 14:
When dividing 2880 by 384, we get 7 with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 134160.929687
Subtract 2688 from 2880 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.

Moving on to step 15:
384 goes into 1920 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 134160.9296875
The remainder is 0 after subtracting 1920 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 16:
If we divide 0 by 384, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 134160.9296875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 134160.9296875 with a remainder of 0.0.
