90500355 ÷ 672 
The aim is to understand the frequency of 672 in 90500355.

Step 1:
When dividing 9 by 672, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 672

Going ahead to step 2:
When dividing 90 by 672, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 672

Advancing to step 3:
672 goes into 905 1 times with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
If we take 672 away from 905, we end up with 233.
Include the next digit (0) from the dividend after 233, then repeat: 2330 / 672

Let's proceed to step 4:
672 can be fit into 2330 3 times, resulting in a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 314 after subtracting 2016 from 2330.
Grab the next digit (0) from the dividend, add it to 314, then carry on: 3140 / 672

Step 5:
672 goes into 3140 4 times with a remainder of 452.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 2688 from 3140 leaves us with 452.
Grab the next digit (3) from the dividend, add it to 452, then carry on: 4523 / 672

Advancing to step 6:
4523 divided by 672 is 6 with a remainder of 491.
The next digit of our result is 6. 
Result so far: 1346.0
Deduct 4032 from 4523 and we're left with 491.
Take the next digit (5) from the dividend and append it to 491, then repeat: 4915 / 672

Step 7:
4915 divided by 672 is 7 with a remainder of 211.
The next digit of our result is 7. 
Result so far: 13467.0
Deduct 4704 from 4915 and we're left with 211.
Include the next digit (5) from the dividend after 211, then repeat: 2115 / 672

Let's proceed to step 8:
The number 672 fits into 2115 3 times, leaving a remainder of 99.
The next digit of our result is 3. 
Result so far: 134673.0
The remainder is 99 after subtracting 2016 from 2115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
990 divided by 672 is 1 with a remainder of 318.
Use 1 as the next digit of our solution. 
Result so far: 134673.1
If we take 672 away from 990, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 10:
3180 divided by 672 is 4 with a remainder of 492.
Put 4 as the next digit of the answer. 
Result so far: 134673.14
Deduct 2688 from 3180 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 11:
When dividing 4920 by 672, we get 7 with a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 134673.147
Subtracting 4704 from 4920 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
The number 672 fits into 2160 3 times, leaving a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 134673.1473
If we subtract 2016 from 2160, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
When dividing 1440 by 672, we get 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 134673.14732
If we subtract 1344 from 1440, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
672 can be fit into 960 1 times, resulting in a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 134673.147321
The remainder is 288 after subtracting 672 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
If we divide 2880 by 672, we get 4 and a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 134673.1473214
If we subtract 2688 from 2880, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 16:
672 can be fit into 1920 2 times, resulting in a remainder of 576.
Write down 2 as next digit of the result. 
Result so far: 134673.14732142
Deduct 1344 from 1920 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

After the division, we end up with 134673.14732142 and a remainder of 5.76e-07.
