86601111 ÷ 672 
The aim is to understand the frequency of 672 in 86601111.

Going ahead to step 1:
When dividing 8 by 672, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 672

On to step 2:
672 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 672

Step 3:
672 goes into 866 1 times with a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 194 after subtracting 672 from 866.
Grab the next digit (0) from the dividend, add it to 194, then carry on: 1940 / 672

Going ahead to step 4:
672 goes into 1940 2 times with a remainder of 596.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1344 from 1940, we get 596.
Fetch the next digit (1) from the dividend, attach it to 596 and continue: 5961 / 672

Moving on to step 5:
5961 divided by 672 is 8 with a remainder of 585.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 5376 from 5961 leaves us with 585.
Append the next digit (1) from the dividend to 585 and continue with: 5851 / 672

Moving on to step 6:
The number 672 fits into 5851 8 times, leaving a remainder of 475.
Write down 8 as next digit of the result. 
Result so far: 1288.0
If we subtract 5376 from 5851, we get 475.
Bring next digit (1) of the dividend behind the 475 and repeat the process: 4751 / 672

Moving on to step 7:
4751 divided by 672 is 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 12887.0
Subtracting 4704 from 4751 leaves us with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 672

Going ahead to step 8:
When dividing 471 by 672, we get 0 with a remainder of 471.
Record the quotient 0 as the next digit in the result. 
Result so far: 128870.0
The remainder is 471 after subtracting 0 from 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 9:
4710 divided by 672 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 128870.7
The remainder is 6 after subtracting 4704 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 672, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 128870.7
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
672 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 128870.7
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 128870.7, with a leftover of 0.06.
