We look at the division of 29138987 by 672 
The aim is to understand the frequency of 672 in 29138987.

Moving on to step 1:
672 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 672

Moving on to step 2:
672 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 672

Moving on to step 3:
The number 672 fits into 291 0 times, leaving a remainder of 291.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 291 and we're left with 291.
Grab the next digit (3) from the dividend, add it to 291, then carry on: 2913 / 672

Let's proceed to step 4:
If we divide 2913 by 672, we get 4 and a remainder of 225.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2688 from 2913 to get 225.
Bring next digit (8) of the dividend behind the 225 and repeat the process: 2258 / 672

Step 5:
672 goes into 2258 3 times with a remainder of 242.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 2016 away from 2258, we end up with 242.
Take the next digit (9) from the dividend and append it to 242, then repeat: 2429 / 672

On to step 6:
672 can be fit into 2429 3 times, resulting in a remainder of 413.
Put 3 as the next digit of the answer. 
Result so far: 433.0
Subtract 2016 from 2429 to get 413.
Append the next digit (8) from the dividend to 413 and continue with: 4138 / 672

Going ahead to step 7:
672 goes into 4138 6 times with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 4336.0
If we take 4032 away from 4138, we end up with 106.
Take the next digit (7) from the dividend and append it to 106, then repeat: 1067 / 672

Going ahead to step 8:
672 goes into 1067 1 times with a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 43361.0
Deduct 672 from 1067 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 9:
When dividing 3950 by 672, we get 5 with a remainder of 590.
Put 5 as the next digit of the answer. 
Result so far: 43361.5
Subtracting 3360 from 3950 leaves us with 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 10:
672 goes into 5900 8 times with a remainder of 524.
The next digit of our result is 8. 
Result so far: 43361.58
Subtracting 5376 from 5900 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 11:
672 can be fit into 5240 7 times, resulting in a remainder of 536.
Put 7 as the next digit of the answer. 
Result so far: 43361.587
Deduct 4704 from 5240 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 12:
5360 divided by 672 is 7 with a remainder of 656.
Write down 7 as next digit of the result. 
Result so far: 43361.5877
If we subtract 4704 from 5360, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The quotient of the division is 43361.5877, and the remainder is 0.00656.
