903370 divided by 51 
The aim is to understand the frequency of 51 in 903370.

Let's proceed to step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 51

Step 2:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 90, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 51

Step 3:
51 can be fit into 393 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 357 from 393 and we're left with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 51

Let's proceed to step 4:
51 can be fit into 363 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 177.0
The remainder is 6 after subtracting 357 from 363.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 51

On to step 5:
51 goes into 67 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1771.0
Deduct 51 from 67 and we're left with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 51

On to step 6:
51 goes into 160 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 17713.0
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
51 goes into 70 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 17713.1
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
190 divided by 51 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 17713.13
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17713.137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
130 divided by 51 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 17713.1372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17713.13725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
If we divide 250 by 51, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 17713.137254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 17713.1372549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
10 divided by 51 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17713.1372549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 17713.1372549 and a remainder of 1e-08.
