We look at the division of 75988281 by 674 
The aim is to understand the frequency of 674 in 75988281.

Step 1:
When dividing 7 by 674, we get 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.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 674

Moving on to step 2:
If we divide 75 by 674, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 674

Moving on to step 3:
759 divided by 674 is 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 674 from 759, we get 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 674

Let's proceed to step 4:
If we divide 858 by 674, we get 1 and a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 184 after subtracting 674 from 858.
Append the next digit (8) from the dividend to 184 and continue with: 1848 / 674

Step 5:
The number 674 fits into 1848 2 times, leaving a remainder of 500.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtracting 1348 from 1848 leaves us with 500.
Grab the next digit (2) from the dividend, add it to 500, then carry on: 5002 / 674

On to step 6:
5002 divided by 674 is 7 with a remainder of 284.
Write down 7 as next digit of the result. 
Result so far: 1127.0
If we take 4718 away from 5002, we end up with 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 674

Advancing to step 7:
When dividing 2848 by 674, we get 4 with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 11274.0
If we subtract 2696 from 2848, we get 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 674

Moving on to step 8:
674 can be fit into 1521 2 times, resulting in a remainder of 173.
Write down 2 as next digit of the result. 
Result so far: 112742.0
Deduct 1348 from 1521 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
674 goes into 1730 2 times with a remainder of 382.
Write down 2 as next digit of the result. 
Result so far: 112742.2
Deduct 1348 from 1730 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 10:
674 can be fit into 3820 5 times, resulting in a remainder of 450.
The next digit of our result is 5. 
Result so far: 112742.25
The remainder is 450 after subtracting 3370 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
The number 674 fits into 4500 6 times, leaving a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 112742.256
Deduct 4044 from 4500 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
The number 674 fits into 4560 6 times, leaving a remainder of 516.
Put 6 as the next digit of the answer. 
Result so far: 112742.2566
If we take 4044 away from 4560, we end up 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.

The final result is 112742.2566 with a remainder of 0.00516.
