We divide 667980 by 67
The aim is to understand the frequency of 67 in 667980.

Moving on to step 1:
6 divided by 67 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 67

On to step 2:
67 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 67

On to step 3:
67 goes into 667 9 times with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 603 away from 667, we end up with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 67

Advancing to step 4:
67 can be fit into 649 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 603 from 649 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 67

Going ahead to step 5:
468 divided by 67 is 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 996.0
Deduct 402 from 468 and we're left with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 67

On to step 6:
660 divided by 67 is 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 9969.0
Deduct 603 from 660 and we're left 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.

Let's proceed to step 7:
570 divided by 67 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 9969.8
If we take 536 away from 570, we end up 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.

Going ahead to step 8:
When dividing 340 by 67, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9969.85
If we subtract 335 from 340, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
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: 9969.85
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.

Advancing to step 10:
The number 67 fits into 500 7 times, leaving a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 9969.8507
Subtract 469 from 500 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
67 goes into 310 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 9969.85074
Subtract 268 from 310 to 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.

Step 12:
When dividing 420 by 67, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 9969.850746
If we take 402 away from 420, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
67 goes into 180 2 times with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 9969.8507462
Deduct 134 from 180 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
67 goes into 460 6 times with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 9969.85074626
If we take 402 away from 460, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 9969.85074626, and the remainder is 5.8e-08.
