74547079 ÷ 643 
The aim is to understand the frequency of 643 in 74547079.

Moving on to step 1:
643 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 643

Moving on to step 2:
The number 643 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 643

Advancing to step 3:
643 goes into 745 1 times with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 643 from 745 leaves us with 102.
Bring next digit (4) of the dividend behind the 102 and repeat the process: 1024 / 643

Let's proceed to step 4:
If we divide 1024 by 643, we get 1 and a remainder of 381.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 643 from 1024, we get 381.
Grab the next digit (7) from the dividend, add it to 381, then carry on: 3817 / 643

Advancing to step 5:
643 goes into 3817 5 times with a remainder of 602.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 3215 from 3817, we get 602.
Include the next digit (0) from the dividend after 602, then repeat: 6020 / 643

On to step 6:
6020 divided by 643 is 9 with a remainder of 233.
The next digit of our result is 9. 
Result so far: 1159.0
If we subtract 5787 from 6020, we get 233.
Append the next digit (7) from the dividend to 233 and continue with: 2337 / 643

Going ahead to step 7:
When dividing 2337 by 643, we get 3 with a remainder of 408.
Write down 3 as next digit of the result. 
Result so far: 11593.0
Subtract 1929 from 2337 to get 408.
Grab the next digit (9) from the dividend, add it to 408, then carry on: 4089 / 643

Step 8:
The number 643 fits into 4089 6 times, leaving a remainder of 231.
Record the quotient 6 as the next digit in the result. 
Result so far: 115936.0
Deduct 3858 from 4089 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
When dividing 2310 by 643, we get 3 with a remainder of 381.
The number 3 becomes the next digit in our result. 
Result so far: 115936.3
Subtract 1929 from 2310 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 10:
643 can be fit into 3810 5 times, resulting in a remainder of 595.
Use 5 as the next digit of our solution. 
Result so far: 115936.35
If we subtract 3215 from 3810, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 11:
5950 divided by 643 is 9 with a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 115936.359
If we take 5787 away from 5950, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 12:
643 can be fit into 1630 2 times, resulting in a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 115936.3592
If we take 1286 away from 1630, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 13:
643 goes into 3440 5 times with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 115936.35925
If we take 3215 away from 3440, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 14:
643 goes into 2250 3 times with a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 115936.359253
Subtracting 1929 from 2250 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 15:
643 goes into 3210 4 times with a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 115936.3592534
Deduct 2572 from 3210 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Let's proceed to step 16:
When dividing 6380 by 643, we get 9 with a remainder of 593.
Write down 9 as next digit of the result. 
Result so far: 115936.35925349
The remainder is 593 after subtracting 5787 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

In conclusion, the division gives 115936.35925349 with a balance of 5.93e-07.
