We're dividing 74091872 by 672 
The aim is to understand the frequency of 672 in 74091872.

Advancing to step 1:
When dividing 7 by 672, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 672

Going ahead to step 2:
If we divide 74 by 672, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 672

Let's proceed to step 3:
When dividing 740 by 672, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 672 from 740 to get 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 672

On to step 4:
689 divided by 672 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 672 from 689 leaves us with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 672

Step 5:
The number 672 fits into 171 0 times, leaving a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtracting 0 from 171 leaves us with 171.
Fetch the next digit (8) from the dividend, attach it to 171 and continue: 1718 / 672

Advancing to step 6:
1718 divided by 672 is 2 with a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 1102.0
Subtract 1344 from 1718 to get 374.
Bring next digit (7) of the dividend behind the 374 and repeat the process: 3747 / 672

Advancing to step 7:
The number 672 fits into 3747 5 times, leaving a remainder of 387.
Write down 5 as next digit of the result. 
Result so far: 11025.0
If we take 3360 away from 3747, we end up with 387.
Fetch the next digit (2) from the dividend, attach it to 387 and continue: 3872 / 672

Step 8:
3872 divided by 672 is 5 with a remainder of 512.
Record the quotient 5 as the next digit in the result. 
Result so far: 110255.0
Subtract 3360 from 3872 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 9:
The number 672 fits into 5120 7 times, leaving a remainder of 416.
Record the quotient 7 as the next digit in the result. 
Result so far: 110255.7
Subtract 4704 from 5120 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 10:
The number 672 fits into 4160 6 times, leaving a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 110255.76
Subtract 4032 from 4160 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 11:
The number 672 fits into 1280 1 times, leaving a remainder of 608.
Write down 1 as next digit of the result. 
Result so far: 110255.761
Subtracting 672 from 1280 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 12:
When dividing 6080 by 672, we get 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 110255.7619
Subtract 6048 from 6080 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
When dividing 320 by 672, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 110255.7619
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
When dividing 3200 by 672, we get 4 with a remainder of 512.
The next digit of our result is 4. 
Result so far: 110255.761904
If we subtract 2688 from 3200, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 15:
When dividing 5120 by 672, we get 7 with a remainder of 416.
The number 7 becomes the next digit in our result. 
Result so far: 110255.7619047
If we take 4704 away from 5120, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
If we divide 4160 by 672, we get 6 and a remainder of 128.
The next digit of our result is 6. 
Result so far: 110255.76190476
Deduct 4032 from 4160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 110255.76190476, and the remainder is 1.28e-07.
