We're dividing 51418616 by 757 
The aim is to understand the frequency of 757 in 51418616.

Step 1:
757 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 757

Going ahead to step 2:
51 divided by 757 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 757

Advancing to step 3:
When dividing 514 by 757, we get 0 with a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 514 and we're left with 514.
Include the next digit (1) from the dividend after 514, then repeat: 5141 / 757

Advancing to step 4:
757 can be fit into 5141 6 times, resulting in a remainder of 599.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4542 from 5141, we get 599.
Include the next digit (8) from the dividend after 599, then repeat: 5998 / 757

Step 5:
757 can be fit into 5998 7 times, resulting in a remainder of 699.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 5299 from 5998 to get 699.
Grab the next digit (6) from the dividend, add it to 699, then carry on: 6996 / 757

Let's proceed to step 6:
If we divide 6996 by 757, we get 9 and a remainder of 183.
Put 9 as the next digit of the answer. 
Result so far: 679.0
The remainder is 183 after subtracting 6813 from 6996.
Bring next digit (1) of the dividend behind the 183 and repeat the process: 1831 / 757

Advancing to step 7:
757 can be fit into 1831 2 times, resulting in a remainder of 317.
Use 2 as the next digit of our solution. 
Result so far: 6792.0
Subtracting 1514 from 1831 leaves us with 317.
Append the next digit (6) from the dividend to 317 and continue with: 3176 / 757

Let's proceed to step 8:
757 goes into 3176 4 times with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 67924.0
Deduct 3028 from 3176 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
The number 757 fits into 1480 1 times, leaving a remainder of 723.
Use 1 as the next digit of our solution. 
Result so far: 67924.1
Subtracting 757 from 1480 leaves us with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Step 10:
757 goes into 7230 9 times with a remainder of 417.
Use 9 as the next digit of our solution. 
Result so far: 67924.19
Deduct 6813 from 7230 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 11:
The number 757 fits into 4170 5 times, leaving a remainder of 385.
The next digit of our result is 5. 
Result so far: 67924.195
The remainder is 385 after subtracting 3785 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
757 can be fit into 3850 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 67924.1955
Subtract 3785 from 3850 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 67924.1955, with a leftover of 0.00065.
