51294663 ÷ 394 
Let's see how many times 394 fits into 51294663.

Advancing to step 1:
394 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 394

On to step 2:
If we divide 51 by 394, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 394

Moving on to step 3:
When dividing 512 by 394, we get 1 with a remainder of 118.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 394 away from 512, we end up with 118.
Append the next digit (9) from the dividend to 118 and continue with: 1189 / 394

Moving on to step 4:
The number 394 fits into 1189 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1182 from 1189, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 394

Moving on to step 5:
74 divided by 394 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtract 0 from 74 to get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 394

On to step 6:
When dividing 746 by 394, we get 1 with a remainder of 352.
Use 1 as the next digit of our solution. 
Result so far: 1301.0
Subtract 394 from 746 to get 352.
Take the next digit (6) from the dividend and append it to 352, then repeat: 3526 / 394

Advancing to step 7:
If we divide 3526 by 394, we get 8 and a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 13018.0
If we take 3152 away from 3526, we end up with 374.
Fetch the next digit (3) from the dividend, attach it to 374 and continue: 3743 / 394

Let's proceed to step 8:
If we divide 3743 by 394, we get 9 and a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 130189.0
Deduct 3546 from 3743 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 9:
If we divide 1970 by 394, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 130189.5
If we subtract 1970 from 1970, 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 10:
If we divide 0 by 394, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130189.5
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.

Advancing to step 11:
The number 394 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130189.5
Deduct 0 from 0 and we're left 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.

The quotient of the division is 130189.5, and the remainder is 0.0.
