71563665 divided by 674 
The aim is to understand the frequency of 674 in 71563665.

Step 1:
The number 674 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 674

On to step 2:
The number 674 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 674

Going ahead to step 3:
715 divided by 674 is 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 674 from 715 to get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 674

Step 4:
674 can be fit into 416 0 times, resulting in a remainder of 416.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 416, we end up with 416.
Bring next digit (3) of the dividend behind the 416 and repeat the process: 4163 / 674

Step 5:
674 goes into 4163 6 times with a remainder of 119.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtract 4044 from 4163 to get 119.
Fetch the next digit (6) from the dividend, attach it to 119 and continue: 1196 / 674

Advancing to step 6:
When dividing 1196 by 674, we get 1 with a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 1061.0
Subtract 674 from 1196 to get 522.
Take the next digit (6) from the dividend and append it to 522, then repeat: 5226 / 674

Moving on to step 7:
The number 674 fits into 5226 7 times, leaving a remainder of 508.
The number 7 becomes the next digit in our result. 
Result so far: 10617.0
The remainder is 508 after subtracting 4718 from 5226.
Grab the next digit (5) from the dividend, add it to 508, then carry on: 5085 / 674

Step 8:
5085 divided by 674 is 7 with a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 106177.0
Subtracting 4718 from 5085 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 9:
674 goes into 3670 5 times with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 106177.5
Deduct 3370 from 3670 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
674 can be fit into 3000 4 times, resulting in a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 106177.54
Subtract 2696 from 3000 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 11:
If we divide 3040 by 674, we get 4 and a remainder of 344.
The next digit of our result is 4. 
Result so far: 106177.544
The remainder is 344 after subtracting 2696 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final result is 106177.544 with a remainder of 0.0344.
