428157 ÷ 67 
The aim is to understand the frequency of 67 in 428157.

Moving on to step 1:
4 divided by 67 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 67

Let's proceed to step 2:
If we divide 42 by 67, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 67

On to step 3:
If we divide 428 by 67, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 402 from 428 to get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 67

Let's proceed to step 4:
67 can be fit into 261 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 201 from 261 leaves us with 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 67

Let's proceed to step 5:
When dividing 605 by 67, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 639.0
Subtract 603 from 605 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 67

Advancing to step 6:
If we divide 27 by 67, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 6390.0
The remainder is 27 after subtracting 0 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
67 goes into 270 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 6390.4
Subtracting 268 from 270 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
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: 6390.4
If we subtract 0 from 20, we 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.

Moving on to step 9:
67 goes into 200 2 times with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 6390.402
Deduct 134 from 200 and we're left 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.

Going ahead to step 10:
If we divide 660 by 67, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 6390.4029
If we take 603 away from 660, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 11:
If we divide 570 by 67, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 6390.40298
Subtract 536 from 570 to get 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 12:
If we divide 340 by 67, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6390.402985
Subtracting 335 from 340 leaves us 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.

Step 13:
67 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 6390.402985
Subtract 0 from 50 to get 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 14:
67 can be fit into 500 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 6390.40298507
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.

After the division, we end up with 6390.40298507 and a remainder of 3.1e-08.
