815504 ÷ 67 
The aim is to understand the frequency of 67 in 815504.

Step 1:
When dividing 8 by 67, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 67

Going ahead to step 2:
67 can be fit into 81 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 67 from 81, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 67

Going ahead to step 3:
The number 67 fits into 145 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 134 from 145 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 67

Step 4:
67 can be fit into 115 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 67 away from 115, we end up with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 67

Let's proceed to step 5:
480 divided by 67 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 1217.0
If we subtract 469 from 480, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 67

Advancing to step 6:
If we divide 114 by 67, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 12171.0
If we subtract 67 from 114, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
The number 67 fits into 470 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 12171.7
If we subtract 469 from 470, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 67 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12171.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
67 can be fit into 100 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 12171.701
Subtracting 67 from 100 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
When dividing 330 by 67, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 12171.7014
If we take 268 away from 330, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
The number 67 fits into 620 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 12171.70149
Deduct 603 from 620 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
67 goes into 170 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 12171.701492
Subtracting 134 from 170 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
When dividing 360 by 67, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12171.7014925
If we take 335 away from 360, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 67, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 12171.70149253
If we take 201 away from 250, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 12171.70149253 and a remainder of 4.9e-08.
