81185475 ÷ 672 
The aim is to understand the frequency of 672 in 81185475.

Step 1:
672 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 672

Going ahead to step 2:
672 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 672

Advancing to step 3:
When dividing 811 by 672, we get 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 672 from 811, we get 139.
Append the next digit (8) from the dividend to 139 and continue with: 1398 / 672

Step 4:
If we divide 1398 by 672, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1344 from 1398, we get 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 672

Let's proceed to step 5:
When dividing 545 by 672, we get 0 with a remainder of 545.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Deduct 0 from 545 and we're left with 545.
Take the next digit (4) from the dividend and append it to 545, then repeat: 5454 / 672

Step 6:
If we divide 5454 by 672, we get 8 and a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 1208.0
Subtract 5376 from 5454 to get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 672

On to step 7:
787 divided by 672 is 1 with a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 12081.0
Subtract 672 from 787 to get 115.
Take the next digit (5) from the dividend and append it to 115, then repeat: 1155 / 672

Going ahead to step 8:
672 can be fit into 1155 1 times, resulting in a remainder of 483.
The next digit of our result is 1. 
Result so far: 120811.0
Subtracting 672 from 1155 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Step 9:
672 can be fit into 4830 7 times, resulting in a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 120811.7
Subtract 4704 from 4830 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 10:
672 can be fit into 1260 1 times, resulting in a remainder of 588.
Record the quotient 1 as the next digit in the result. 
Result so far: 120811.71
Subtract 672 from 1260 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 11:
The number 672 fits into 5880 8 times, leaving a remainder of 504.
Put 8 as the next digit of the answer. 
Result so far: 120811.718
Deduct 5376 from 5880 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 12:
672 can be fit into 5040 7 times, resulting in a remainder of 336.
The next digit of our result is 7. 
Result so far: 120811.7187
If we take 4704 away from 5040, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 13:
3360 divided by 672 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 120811.71875
Subtracting 3360 from 3360 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
672 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120811.71875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
0 divided by 672 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 120811.71875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 120811.71875 with a remainder of 0.0.
