606398 divided by 67 
The aim is to understand the frequency of 67 in 606398.

Step 1:
When dividing 6 by 67, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 67

Advancing to step 2:
The number 67 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 67

Going ahead to step 3:
67 goes into 606 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 603 from 606 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 67

Going ahead to step 4:
67 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 33, we get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 67

Moving on to step 5:
When dividing 339 by 67, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 905.0
If we subtract 335 from 339, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 67

Advancing to step 6:
If we divide 48 by 67, we get 0 and a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 9050.0
The remainder is 48 after subtracting 0 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 67 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 9050.7
Subtracting 469 from 480 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
67 goes into 110 1 times with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 9050.71
Deduct 67 from 110 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
When dividing 430 by 67, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 9050.716
The remainder is 28 after subtracting 402 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
67 can be fit into 280 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 9050.7164
If we subtract 268 from 280, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 67 is 1 with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 9050.71641
Subtracting 67 from 120 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
530 divided by 67 is 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 9050.716417
The remainder is 61 after subtracting 469 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
67 can be fit into 610 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9050.7164179
Subtracting 603 from 610 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
70 divided by 67 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9050.71641791
If we subtract 67 from 70, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 9050.71641791, and the remainder is 3e-09.
