Let's divide 378732 by 51
The aim is to understand the frequency of 51 in 378732.

Going ahead to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 51

Let's proceed to step 2:
51 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 51

Step 3:
51 can be fit into 378 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 357 away from 378, we end up with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 51

Step 4:
If we divide 217 by 51, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 204 from 217, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 51

Let's proceed to step 5:
The number 51 fits into 133 2 times, leaving a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 742.0
Subtract 102 from 133 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 51

Moving on to step 6:
312 divided by 51 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 7426.0
Deduct 306 from 312 and we're left 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.

Step 7:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 7426.1
If we take 51 away from 60, we end up 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 8:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 7426.11
The remainder is 39 after subtracting 51 from 90.
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 7426.11, with a leftover of 0.039.
