Let's divide 661338 by 67
The aim is to understand the frequency of 67 in 661338.

Advancing to step 1:
The number 67 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 67

On to step 2:
If we divide 66 by 67, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 67

Going ahead to step 3:
The number 67 fits into 661 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 603 from 661 to get 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 67

Step 4:
67 can be fit into 583 8 times, resulting in a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 47 after subtracting 536 from 583.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 67

Step 5:
67 can be fit into 473 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
Deduct 469 from 473 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 67

Step 6:
48 divided by 67 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 9870.0
Subtract 0 from 48 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 67 fits into 480 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 9870.7
The remainder is 11 after subtracting 469 from 480.
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.
Put 1 as the next digit of the answer. 
Result so far: 9870.71
The remainder is 43 after subtracting 67 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
When dividing 430 by 67, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 9870.716
Subtracting 402 from 430 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
67 can be fit into 280 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 9870.7164
Subtracting 268 from 280 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 67 is 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 9870.71641
If we subtract 67 from 120, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 12:
67 can be fit into 530 7 times, resulting in a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 9870.716417
If we take 469 away from 530, we end up with 61.
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:
If we divide 610 by 67, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 9870.7164179
Subtract 603 from 610 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
If we divide 70 by 67, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 9870.71641791
If we take 67 away from 70, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 9870.71641791 with a remaining 3e-09.
