We look at the division of 79932651 by 643 
The aim is to understand the frequency of 643 in 79932651.

Moving on to step 1:
643 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 643

On to step 2:
643 can be fit into 79 0 times, resulting in a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 643

Going ahead to step 3:
If we divide 799 by 643, we get 1 and a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 643 from 799 and we're left with 156.
Grab the next digit (3) from the dividend, add it to 156, then carry on: 1563 / 643

On to step 4:
1563 divided by 643 is 2 with a remainder of 277.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 277 after subtracting 1286 from 1563.
Append the next digit (2) from the dividend to 277 and continue with: 2772 / 643

Let's proceed to step 5:
643 can be fit into 2772 4 times, resulting in a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we subtract 2572 from 2772, we get 200.
Grab the next digit (6) from the dividend, add it to 200, then carry on: 2006 / 643

Moving on to step 6:
If we divide 2006 by 643, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 1243.0
Subtract 1929 from 2006 to get 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 643

Step 7:
775 divided by 643 is 1 with a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 12431.0
If we take 643 away from 775, we end up with 132.
Grab the next digit (1) from the dividend, add it to 132, then carry on: 1321 / 643

On to step 8:
643 goes into 1321 2 times with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 124312.0
The remainder is 35 after subtracting 1286 from 1321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 643, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 124312.0
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
The number 643 fits into 3500 5 times, leaving a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 124312.05
If we subtract 3215 from 3500, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 11:
2850 divided by 643 is 4 with a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 124312.054
Subtract 2572 from 2850 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 12:
The number 643 fits into 2780 4 times, leaving a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 124312.0544
The remainder is 208 after subtracting 2572 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 124312.0544 with a balance of 0.00208.
