We divide 306432 by 51
The aim is to understand the frequency of 51 in 306432.

Step 1:
3 divided by 51 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 51

On to step 2:
51 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 51

Advancing to step 3:
The number 51 fits into 306 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 306 from 306 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 51

On to step 4:
When dividing 4 by 51, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 60.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 51

Going ahead to step 5:
51 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 600.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 51

Going ahead to step 6:
When dividing 432 by 51, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 6008.0
Subtracting 408 from 432 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
If we divide 240 by 51, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 6008.4
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 6008.47
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 51, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6008.47
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
51 goes into 300 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6008.4705
Subtract 255 from 300 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.

On to step 11:
51 goes into 450 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6008.47058
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.

Going ahead to step 12:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6008.470588
Deduct 408 from 420 and we're left with 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 6008.470588, and the remainder is 1.2e-06.
