We're dividing 747390 by 14 
We want to figure out the number of times 747390 can be divided by 14.

Step 1:
14 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 14

Going ahead to step 2:
74 divided by 14 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 70 from 74 and we're left with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 14

Going ahead to step 3:
14 can be fit into 47 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 42 from 47 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 14

Step 4:
If we divide 53 by 14, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 533.0
Deduct 42 from 53 and we're left with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 14

On to step 5:
The number 14 fits into 119 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 5338.0
Deduct 112 from 119 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 14

Going ahead to step 6:
The number 14 fits into 70 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 53385.0
If we take 70 away from 70, we end up 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.

On to step 7:
0 divided by 14 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 53385.0
Subtracting 0 from 0 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.

Going ahead to step 8:
14 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 53385.0
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 53385.0, with a leftover of 0.0.
