Let's divide 744696 by 51
The aim is to understand the frequency of 51 in 744696.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 51

Going ahead to step 2:
74 divided by 51 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 51 from 74 leaves us with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 51

Let's proceed to step 3:
When dividing 234 by 51, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 204 from 234 and we're left with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 51

Step 4:
306 divided by 51 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Deduct 306 from 306 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 51

Advancing to step 5:
The number 51 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 1460.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 51

On to step 6:
51 goes into 96 1 times with a remainder of 45.
The next digit of our result is 1. 
Result so far: 14601.0
Subtract 51 from 96 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 14601.8
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 14601.88
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 14601.88, and the remainder is 0.012.
