51217086 ÷ 384 
We want to divide 51217086 by 384.

Going ahead to step 1:
5 divided by 384 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 384

Going ahead to step 2:
When dividing 51 by 384, we get 0 with 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 (2) of the dividend behind the 51 and repeat the process: 512 / 384

Advancing to step 3:
The number 384 fits into 512 1 times, leaving a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 128 after subtracting 384 from 512.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 384

Step 4:
384 goes into 1281 3 times with a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1152 from 1281 to get 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 384

Going ahead to step 5:
When dividing 1297 by 384, we get 3 with a remainder of 145.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we take 1152 away from 1297, we end up with 145.
Bring next digit (0) of the dividend behind the 145 and repeat the process: 1450 / 384

On to step 6:
If we divide 1450 by 384, we get 3 and a remainder of 298.
The next digit of our result is 3. 
Result so far: 1333.0
If we take 1152 away from 1450, we end up with 298.
Append the next digit (8) from the dividend to 298 and continue with: 2988 / 384

Moving on to step 7:
384 goes into 2988 7 times with a remainder of 300.
Put 7 as the next digit of the answer. 
Result so far: 13337.0
Subtracting 2688 from 2988 leaves us with 300.
Bring next digit (6) of the dividend behind the 300 and repeat the process: 3006 / 384

Advancing to step 8:
3006 divided by 384 is 7 with a remainder of 318.
Record the quotient 7 as the next digit in the result. 
Result so far: 133377.0
Deduct 2688 from 3006 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
If we divide 3180 by 384, we get 8 and a remainder of 108.
The next digit of our result is 8. 
Result so far: 133377.8
If we take 3072 away from 3180, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
384 can be fit into 1080 2 times, resulting in a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 133377.82
Deduct 768 from 1080 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
3120 divided by 384 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 133377.828
Subtracting 3072 from 3120 leaves us 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.

Advancing to step 12:
The number 384 fits into 480 1 times, leaving a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 133377.8281
If we subtract 384 from 480, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
When dividing 960 by 384, we get 2 with a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 133377.82812
Deduct 768 from 960 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
1920 divided by 384 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 133377.828125
Subtracting 1920 from 1920 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
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: 133377.828125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
The number 384 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 133377.828125
If we subtract 0 from 0, we get 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 outcome is 133377.828125, with a leftover of 0.0.
