We look at the division of 353997 by 67 
The aim is to understand the frequency of 67 in 353997.

Going ahead to step 1:
If we divide 3 by 67, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 67

Moving on to step 2:
When dividing 35 by 67, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 67

Step 3:
67 goes into 353 5 times with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 335 from 353 and we're left with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 67

Advancing to step 4:
The number 67 fits into 189 2 times, leaving a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 134 from 189 leaves us with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 67

Going ahead to step 5:
67 goes into 559 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 528.0
If we take 536 away from 559, we end up with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 67

Moving on to step 6:
When dividing 237 by 67, we get 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 5283.0
The remainder is 36 after subtracting 201 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 67 fits into 360 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5283.5
The remainder is 25 after subtracting 335 from 360.
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 8:
If we divide 250 by 67, we get 3 and a remainder of 49.
The next digit of our result is 3. 
Result so far: 5283.53
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.

Moving on to step 9:
490 divided by 67 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 5283.537
The remainder is 21 after subtracting 469 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
210 divided by 67 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 5283.5373
Deduct 201 from 210 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
67 goes into 90 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 5283.53731
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.

On to step 12:
230 divided by 67 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 5283.537313
Deduct 201 from 230 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 67 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 5283.5373134
Subtracting 268 from 290 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
The number 67 fits into 220 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 5283.53731343
If we subtract 201 from 220, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 5283.53731343 with a remaining 1.9e-08.
