420561 ÷ 67 
The aim is to understand the frequency of 67 in 420561.

Step 1:
67 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 67

Step 2:
67 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 67

Let's proceed to step 3:
If we divide 420 by 67, we get 6 and a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 402 from 420 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 67

Going ahead to step 4:
If we divide 185 by 67, we get 2 and a remainder of 51.
The next digit of our result is 2. 
Result so far: 62.0
Subtracting 134 from 185 leaves us with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 67

Step 5:
516 divided by 67 is 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 627.0
Subtracting 469 from 516 leaves us with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 67

Step 6:
67 goes into 471 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 6277.0
The remainder is 2 after subtracting 469 from 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 67, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6277.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 67, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 6277.02
If we take 134 away from 200, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
If we divide 660 by 67, we get 9 and a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 6277.029
The remainder is 57 after subtracting 603 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
570 divided by 67 is 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 6277.0298
Deduct 536 from 570 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
67 can be fit into 340 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 6277.02985
If we take 335 away from 340, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 67 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 6277.02985
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 67, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 6277.0298507
Subtracting 469 from 500 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
The number 67 fits into 310 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 6277.02985074
If we subtract 268 from 310, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 6277.02985074 with a remainder of 4.2e-08.
