1204665 divided by 757 
The aim is to understand the frequency of 757 in 1204665.

Advancing to step 1:
757 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 757

On to step 2:
757 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 757

Moving on to step 3:
If we divide 120 by 757, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 757

Let's proceed to step 4:
1204 divided by 757 is 1 with a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 447 after subtracting 757 from 1204.
Include the next digit (6) from the dividend after 447, then repeat: 4476 / 757

Step 5:
757 goes into 4476 5 times with a remainder of 691.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 3785 away from 4476, we end up with 691.
Append the next digit (6) from the dividend to 691 and continue with: 6916 / 757

Let's proceed to step 6:
When dividing 6916 by 757, we get 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we take 6813 away from 6916, we end up with 103.
Bring next digit (5) of the dividend behind the 103 and repeat the process: 1035 / 757

Advancing to step 7:
757 can be fit into 1035 1 times, resulting in a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
Subtract 757 from 1035 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 8:
When dividing 2780 by 757, we get 3 with a remainder of 509.
The next digit of our result is 3. 
Result so far: 1591.3
Subtract 2271 from 2780 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Going ahead to step 9:
757 goes into 5090 6 times with a remainder of 548.
Write down 6 as next digit of the result. 
Result so far: 1591.36
Deduct 4542 from 5090 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
757 can be fit into 5480 7 times, resulting in a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 1591.367
Subtracting 5299 from 5480 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 11:
757 can be fit into 1810 2 times, resulting in a remainder of 296.
The number 2 becomes the next digit in our result. 
Result so far: 1591.3672
Subtract 1514 from 1810 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
The number 757 fits into 2960 3 times, leaving a remainder of 689.
Write down 3 as next digit of the result. 
Result so far: 1591.36723
If we take 2271 away from 2960, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 13:
757 goes into 6890 9 times with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 1591.367239
If we take 6813 away from 6890, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 14:
757 goes into 770 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1591.3672391
If we subtract 757 from 770, we get 13.
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 15:
757 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 1591.3672391
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 1591.3672391 and a remainder of 1.3e-07.
