We look at the division of 42694385 by 672 
The aim is to understand the frequency of 672 in 42694385.

Step 1:
When dividing 4 by 672, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 672

Step 2:
672 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 672

Advancing to step 3:
If we divide 426 by 672, we get 0 and a remainder of 426.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Include the next digit (9) from the dividend after 426, then repeat: 4269 / 672

Let's proceed to step 4:
672 can be fit into 4269 6 times, resulting in a remainder of 237.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4032 from 4269 leaves us with 237.
Fetch the next digit (4) from the dividend, attach it to 237 and continue: 2374 / 672

Moving on to step 5:
When dividing 2374 by 672, we get 3 with a remainder of 358.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 2016 away from 2374, we end up with 358.
Grab the next digit (3) from the dividend, add it to 358, then carry on: 3583 / 672

On to step 6:
672 can be fit into 3583 5 times, resulting in a remainder of 223.
Use 5 as the next digit of our solution. 
Result so far: 635.0
If we take 3360 away from 3583, we end up with 223.
Append the next digit (8) from the dividend to 223 and continue with: 2238 / 672

On to step 7:
When dividing 2238 by 672, we get 3 with a remainder of 222.
The next digit of our result is 3. 
Result so far: 6353.0
Deduct 2016 from 2238 and we're left with 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 672

Advancing to step 8:
When dividing 2225 by 672, we get 3 with a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 63533.0
If we subtract 2016 from 2225, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
672 can be fit into 2090 3 times, resulting in a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 63533.3
If we subtract 2016 from 2090, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
672 can be fit into 740 1 times, resulting in a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 63533.31
If we subtract 672 from 740, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
If we divide 680 by 672, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 63533.311
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 63533.311 with a remaining 0.0008.
