We're dividing 75816215 by 674 
The aim is to understand the frequency of 674 in 75816215.

Going ahead to step 1:
674 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 674

Going ahead to step 2:
The number 674 fits into 75 0 times, leaving a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 674

Let's proceed to step 3:
674 can be fit into 758 1 times, resulting in a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 674 from 758 to get 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 674

Advancing to step 4:
When dividing 841 by 674, we get 1 with a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 674 from 841, we get 167.
Take the next digit (6) from the dividend and append it to 167, then repeat: 1676 / 674

Going ahead to step 5:
1676 divided by 674 is 2 with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 1348 from 1676 and we're left with 328.
Take the next digit (2) from the dividend and append it to 328, then repeat: 3282 / 674

Moving on to step 6:
When dividing 3282 by 674, we get 4 with a remainder of 586.
The number 4 becomes the next digit in our result. 
Result so far: 1124.0
Deduct 2696 from 3282 and we're left with 586.
Grab the next digit (1) from the dividend, add it to 586, then carry on: 5861 / 674

Going ahead to step 7:
5861 divided by 674 is 8 with a remainder of 469.
Write down 8 as next digit of the result. 
Result so far: 11248.0
If we subtract 5392 from 5861, we get 469.
Append the next digit (5) from the dividend to 469 and continue with: 4695 / 674

Step 8:
674 goes into 4695 6 times with a remainder of 651.
Write down 6 as next digit of the result. 
Result so far: 112486.0
Subtract 4044 from 4695 to get 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Going ahead to step 9:
If we divide 6510 by 674, we get 9 and a remainder of 444.
Record the quotient 9 as the next digit in the result. 
Result so far: 112486.9
Subtract 6066 from 6510 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 10:
The number 674 fits into 4440 6 times, leaving a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 112486.96
Subtract 4044 from 4440 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 11:
If we divide 3960 by 674, we get 5 and a remainder of 590.
Use 5 as the next digit of our solution. 
Result so far: 112486.965
Subtract 3370 from 3960 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
674 goes into 5900 8 times with a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 112486.9658
Subtracting 5392 from 5900 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 13:
The number 674 fits into 5080 7 times, leaving a remainder of 362.
The number 7 becomes the next digit in our result. 
Result so far: 112486.96587
Deduct 4718 from 5080 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 14:
When dividing 3620 by 674, we get 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 112486.965875
Deduct 3370 from 3620 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 15:
If we divide 2500 by 674, we get 3 and a remainder of 478.
Use 3 as the next digit of our solution. 
Result so far: 112486.9658753
If we subtract 2022 from 2500, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 16:
When dividing 4780 by 674, we get 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 112486.96587537
If we subtract 4718 from 4780, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 112486.96587537 and a remainder of 6.2e-08.
