We're dividing 73515385 by 67 
The aim is to understand the frequency of 67 in 73515385.

Advancing to step 1:
7 divided by 67 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 67

On to step 2:
67 goes into 73 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 6 after subtracting 67 from 73.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 67

Step 3:
65 divided by 67 is 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 65 to get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 67

Let's proceed to step 4:
67 goes into 651 9 times with a remainder of 48.
The next digit of our result is 9. 
Result so far: 109.0
If we subtract 603 from 651, we get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 67

Step 5:
67 can be fit into 485 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 1097.0
The remainder is 16 after subtracting 469 from 485.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 67

On to step 6:
If we divide 163 by 67, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 10972.0
Subtracting 134 from 163 leaves us with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 67

Step 7:
67 goes into 298 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 109724.0
If we subtract 268 from 298, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 67

On to step 8:
If we divide 305 by 67, we get 4 and a remainder of 37.
The next digit of our result is 4. 
Result so far: 1097244.0
The remainder is 37 after subtracting 268 from 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
When dividing 370 by 67, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1097244.5
Subtracting 335 from 370 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
The number 67 fits into 350 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1097244.55
Deduct 335 from 350 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 1097244.55 with a remainder of 0.015.
