We look at the division of 731388 by 51 
We want to figure out the number of times 731388 can be divided by 51.

Step 1:
The number 51 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 51

Let's proceed to step 2:
73 divided by 51 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 73 leaves us with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 51

Let's proceed to step 3:
51 goes into 221 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 204 away from 221, we end up with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 51

On to step 4:
51 goes into 173 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtract 153 from 173 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 51

On to step 5:
When dividing 208 by 51, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1434.0
Deduct 204 from 208 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 51

Going ahead to step 6:
If we divide 48 by 51, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 14340.0
Subtracting 0 from 48 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 7:
The number 51 fits into 480 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 14340.9
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
If we divide 210 by 51, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14340.94
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
The number 51 fits into 60 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 14340.941
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
90 divided by 51 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 14340.9411
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 14340.9411, with a leftover of 0.00039.
