We're dividing 71731202 by 672 
The aim is to understand the frequency of 672 in 71731202.

Step 1:
If we divide 7 by 672, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 672

Let's proceed to step 2:
672 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 672

Let's proceed to step 3:
When dividing 717 by 672, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 672 from 717 and we're left with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 672

Let's proceed to step 4:
When dividing 453 by 672, we get 0 with a remainder of 453.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 453 after subtracting 0 from 453.
Grab the next digit (1) from the dividend, add it to 453, then carry on: 4531 / 672

Let's proceed to step 5:
The number 672 fits into 4531 6 times, leaving a remainder of 499.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we take 4032 away from 4531, we end up with 499.
Append the next digit (2) from the dividend to 499 and continue with: 4992 / 672

Advancing to step 6:
If we divide 4992 by 672, we get 7 and a remainder of 288.
Write down 7 as next digit of the result. 
Result so far: 1067.0
Deduct 4704 from 4992 and we're left with 288.
Include the next digit (0) from the dividend after 288, then repeat: 2880 / 672

Advancing to step 7:
If we divide 2880 by 672, we get 4 and a remainder of 192.
Write down 4 as next digit of the result. 
Result so far: 10674.0
Deduct 2688 from 2880 and we're left with 192.
Grab the next digit (2) from the dividend, add it to 192, then carry on: 1922 / 672

Let's proceed to step 8:
If we divide 1922 by 672, we get 2 and a remainder of 578.
Put 2 as the next digit of the answer. 
Result so far: 106742.0
If we take 1344 away from 1922, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 9:
5780 divided by 672 is 8 with a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 106742.8
Subtracting 5376 from 5780 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 10:
The number 672 fits into 4040 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 106742.86
If we subtract 4032 from 4040, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
672 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 106742.86
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 672, we get 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 106742.8601
Subtract 672 from 800 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.

Moving on to step 13:
1280 divided by 672 is 1 with a remainder of 608.
Record the quotient 1 as the next digit in the result. 
Result so far: 106742.86011
Deduct 672 from 1280 and we're left 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.

The final result is 106742.86011 with a remainder of 0.000608.
