33947447 ÷ 643 
The aim is to understand the frequency of 643 in 33947447.

Moving on to step 1:
3 divided by 643 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 643

On to step 2:
643 can be fit into 33 0 times, resulting in a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 643

Going ahead to step 3:
643 goes into 339 0 times with a remainder of 339.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 339, we get 339.
Take the next digit (4) from the dividend and append it to 339, then repeat: 3394 / 643

On to step 4:
If we divide 3394 by 643, we get 5 and a remainder of 179.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3215 from 3394 leaves us with 179.
Bring next digit (7) of the dividend behind the 179 and repeat the process: 1797 / 643

On to step 5:
643 can be fit into 1797 2 times, resulting in a remainder of 511.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 1286 from 1797 leaves us with 511.
Take the next digit (4) from the dividend and append it to 511, then repeat: 5114 / 643

Advancing to step 6:
643 can be fit into 5114 7 times, resulting in a remainder of 613.
Write down 7 as next digit of the result. 
Result so far: 527.0
Deduct 4501 from 5114 and we're left with 613.
Fetch the next digit (4) from the dividend, attach it to 613 and continue: 6134 / 643

Going ahead to step 7:
If we divide 6134 by 643, we get 9 and a remainder of 347.
Write down 9 as next digit of the result. 
Result so far: 5279.0
The remainder is 347 after subtracting 5787 from 6134.
Take the next digit (7) from the dividend and append it to 347, then repeat: 3477 / 643

Let's proceed to step 8:
643 can be fit into 3477 5 times, resulting in a remainder of 262.
Record the quotient 5 as the next digit in the result. 
Result so far: 52795.0
If we take 3215 away from 3477, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
If we divide 2620 by 643, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 52795.4
If we take 2572 away from 2620, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
643 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 52795.4
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
When dividing 4800 by 643, we get 7 with a remainder of 299.
Record the quotient 7 as the next digit in the result. 
Result so far: 52795.407
If we take 4501 away from 4800, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 12:
2990 divided by 643 is 4 with a remainder of 418.
The next digit of our result is 4. 
Result so far: 52795.4074
Subtract 2572 from 2990 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 13:
643 can be fit into 4180 6 times, resulting in a remainder of 322.
Use 6 as the next digit of our solution. 
Result so far: 52795.40746
Subtract 3858 from 4180 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 14:
When dividing 3220 by 643, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 52795.407465
If we take 3215 away from 3220, we end up with 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 15:
643 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 52795.407465
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
643 can be fit into 500 0 times, resulting in a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 52795.407465
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 52795.407465 with a balance of 5e-07.
