We look at the division of 691824 by 74 
The aim is to understand the frequency of 74 in 691824.

Step 1:
If we divide 6 by 74, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 74

Advancing to step 2:
69 divided by 74 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 74

Advancing to step 3:
74 goes into 691 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 666 from 691 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 74

Advancing to step 4:
The number 74 fits into 258 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 222 away from 258, we end up with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 74

On to step 5:
The number 74 fits into 362 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 934.0
Subtract 296 from 362 to get 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 74

Advancing to step 6:
664 divided by 74 is 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 9348.0
If we take 592 away from 664, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
74 can be fit into 720 9 times, resulting in a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 9348.9
Deduct 666 from 720 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
74 goes into 540 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 9348.97
Subtract 518 from 540 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
74 goes into 220 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 9348.972
If we take 148 away from 220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
When dividing 720 by 74, we get 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 9348.9729
Deduct 666 from 720 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
When dividing 540 by 74, we get 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 9348.97297
Deduct 518 from 540 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
74 goes into 220 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 9348.972972
Deduct 148 from 220 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
74 can be fit into 720 9 times, resulting in a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 9348.9729729
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
74 goes into 540 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 9348.97297297
Subtracting 518 from 540 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 9348.97297297 and a remainder of 2.2e-08.
