Let's divide 643491 by 67
The aim is to understand the frequency of 67 in 643491.

Let's proceed to step 1:
67 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 67

Going ahead to step 2:
67 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 67

Step 3:
67 can be fit into 643 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 603 away from 643, we end up with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 67

Let's proceed to step 4:
When dividing 404 by 67, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 402 from 404, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 67

Going ahead to step 5:
67 can be fit into 29 0 times, resulting in a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 960.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 67

Moving on to step 6:
The number 67 fits into 291 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 9604.0
The remainder is 23 after subtracting 268 from 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 67, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 9604.3
The remainder is 29 after subtracting 201 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
The number 67 fits into 290 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 9604.34
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 9:
220 divided by 67 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 9604.343
Deduct 201 from 220 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
190 divided by 67 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 9604.3432
If we subtract 134 from 190, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 67, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 9604.34328
If we subtract 536 from 560, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
If we divide 240 by 67, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 9604.343283
If we take 201 away from 240, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
67 can be fit into 390 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 9604.3432835
Subtracting 335 from 390 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
67 can be fit into 550 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 9604.34328358
Deduct 536 from 550 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 9604.34328358, and the remainder is 1.4e-08.
