We divide 76174454 by 648
The aim is to understand the frequency of 648 in 76174454.

Step 1:
7 divided by 648 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 648

Moving on to step 2:
648 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 648

Let's proceed to step 3:
The number 648 fits into 761 1 times, leaving a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 113 after subtracting 648 from 761.
Fetch the next digit (7) from the dividend, attach it to 113 and continue: 1137 / 648

On to step 4:
If we divide 1137 by 648, we get 1 and a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 489 after subtracting 648 from 1137.
Append the next digit (4) from the dividend to 489 and continue with: 4894 / 648

Going ahead to step 5:
648 can be fit into 4894 7 times, resulting in a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 358 after subtracting 4536 from 4894.
Fetch the next digit (4) from the dividend, attach it to 358 and continue: 3584 / 648

Step 6:
The number 648 fits into 3584 5 times, leaving a remainder of 344.
Record the quotient 5 as the next digit in the result. 
Result so far: 1175.0
If we take 3240 away from 3584, we end up with 344.
Bring next digit (5) of the dividend behind the 344 and repeat the process: 3445 / 648

On to step 7:
The number 648 fits into 3445 5 times, leaving a remainder of 205.
The next digit of our result is 5. 
Result so far: 11755.0
If we take 3240 away from 3445, we end up with 205.
Take the next digit (4) from the dividend and append it to 205, then repeat: 2054 / 648

Step 8:
2054 divided by 648 is 3 with a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 117553.0
Subtract 1944 from 2054 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
If we divide 1100 by 648, we get 1 and a remainder of 452.
Use 1 as the next digit of our solution. 
Result so far: 117553.1
Deduct 648 from 1100 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
The number 648 fits into 4520 6 times, leaving a remainder of 632.
The next digit of our result is 6. 
Result so far: 117553.16
If we subtract 3888 from 4520, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
When dividing 6320 by 648, we get 9 with a remainder of 488.
Record the quotient 9 as the next digit in the result. 
Result so far: 117553.169
If we take 5832 away from 6320, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 12:
4880 divided by 648 is 7 with a remainder of 344.
Record the quotient 7 as the next digit in the result. 
Result so far: 117553.1697
If we take 4536 away from 4880, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 13:
648 can be fit into 3440 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 117553.16975
Deduct 3240 from 3440 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
648 goes into 2000 3 times with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 117553.169753
Subtract 1944 from 2000 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 15:
648 can be fit into 560 0 times, resulting in a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 117553.169753
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
648 goes into 5600 8 times with a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 117553.16975308
If we take 5184 away from 5600, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final result is 117553.16975308 with a remainder of 4.16e-07.
