645361 divided by 67 
The aim is to understand the frequency of 67 in 645361.

Moving on to step 1:
6 divided by 67 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 67

Let's proceed to step 2:
64 divided by 67 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 67

On to step 3:
67 goes into 645 9 times with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 603 away from 645, we end up with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 67

Moving on to step 4:
When dividing 423 by 67, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we subtract 402 from 423, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 67

Going ahead to step 5:
The number 67 fits into 216 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 963.0
Subtracting 201 from 216 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 67

Let's proceed to step 6:
If we divide 151 by 67, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 9632.0
The remainder is 17 after subtracting 134 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
67 goes into 170 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 9632.2
Deduct 134 from 170 and we're left 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.

Let's proceed to step 8:
When dividing 360 by 67, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9632.25
If we subtract 335 from 360, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 67 fits into 250 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 9632.253
Deduct 201 from 250 and we're left 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.

Moving on to step 10:
If we divide 490 by 67, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 9632.2537
Deduct 469 from 490 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 67 fits into 210 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 9632.25373
If we subtract 201 from 210, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
If we divide 90 by 67, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 9632.253731
Subtracting 67 from 90 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
If we divide 230 by 67, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 9632.2537313
Subtract 201 from 230 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
If we divide 290 by 67, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 9632.25373134
If we subtract 268 from 290, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 9632.25373134, with a leftover of 2.2e-08.
