We're dividing 747842 by 51 
Let's see how many times 51 fits into 747842.

Step 1:
7 divided by 51 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 51

Going ahead to step 2:
51 goes into 74 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 74, we end up with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 51

On to step 3:
51 goes into 237 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 33 after subtracting 204 from 237.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 51

Step 4:
338 divided by 51 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we subtract 306 from 338, we get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 51

Step 5:
51 goes into 324 6 times with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1466.0
Subtracting 306 from 324 leaves us with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 51

Going ahead to step 6:
If we divide 182 by 51, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 14663.0
Deduct 153 from 182 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 14663.5
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
350 divided by 51 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 14663.56
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 14663.568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 14663.5686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 51 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 14663.56862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 14663.568627
If we take 357 away from 380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 14663.5686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
When dividing 260 by 51, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 14663.56862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 14663.56862745 and a remainder of 5e-09.
