We look at the division of 71475123 by 674 
The aim is to understand the frequency of 674 in 71475123.

Going ahead to step 1:
If we divide 7 by 674, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 674

On to step 2:
If we divide 71 by 674, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 674

On to step 3:
If we divide 714 by 674, we get 1 and a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 674 away from 714, we end up with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 674

Step 4:
If we divide 407 by 674, we get 0 and a remainder of 407.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 407, we get 407.
Take the next digit (5) from the dividend and append it to 407, then repeat: 4075 / 674

Advancing to step 5:
674 goes into 4075 6 times with a remainder of 31.
The next digit of our result is 6. 
Result so far: 106.0
If we take 4044 away from 4075, we end up with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 674

On to step 6:
674 can be fit into 311 0 times, resulting in a remainder of 311.
The number 0 becomes the next digit in our result. 
Result so far: 1060.0
Subtract 0 from 311 to get 311.
Append the next digit (2) from the dividend to 311 and continue with: 3112 / 674

Advancing to step 7:
674 goes into 3112 4 times with a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 10604.0
Subtract 2696 from 3112 to get 416.
Grab the next digit (3) from the dividend, add it to 416, then carry on: 4163 / 674

Let's proceed to step 8:
674 goes into 4163 6 times with a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 106046.0
If we take 4044 away from 4163, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
674 goes into 1190 1 times with a remainder of 516.
The number 1 becomes the next digit in our result. 
Result so far: 106046.1
Subtracting 674 from 1190 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 10:
674 can be fit into 5160 7 times, resulting in a remainder of 442.
The number 7 becomes the next digit in our result. 
Result so far: 106046.17
If we take 4718 away from 5160, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 11:
674 can be fit into 4420 6 times, resulting in a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 106046.176
If we take 4044 away from 4420, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 12:
When dividing 3760 by 674, we get 5 with a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 106046.1765
If we take 3370 away from 3760, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 13:
674 can be fit into 3900 5 times, resulting in a remainder of 530.
Record the quotient 5 as the next digit in the result. 
Result so far: 106046.17655
The remainder is 530 after subtracting 3370 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The final outcome is 106046.17655, with a leftover of 0.00053.
