43943501 ÷ 778 
The aim is to understand the frequency of 778 in 43943501.

Step 1:
The number 778 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 778

On to step 2:
778 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 778

On to step 3:
If we divide 439 by 778, we get 0 and a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 439 to get 439.
Bring next digit (4) of the dividend behind the 439 and repeat the process: 4394 / 778

Advancing to step 4:
The number 778 fits into 4394 5 times, leaving a remainder of 504.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3890 away from 4394, we end up with 504.
Fetch the next digit (3) from the dividend, attach it to 504 and continue: 5043 / 778

Going ahead to step 5:
If we divide 5043 by 778, we get 6 and a remainder of 375.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 4668 from 5043, we get 375.
Include the next digit (5) from the dividend after 375, then repeat: 3755 / 778

On to step 6:
When dividing 3755 by 778, we get 4 with a remainder of 643.
Use 4 as the next digit of our solution. 
Result so far: 564.0
The remainder is 643 after subtracting 3112 from 3755.
Grab the next digit (0) from the dividend, add it to 643, then carry on: 6430 / 778

Advancing to step 7:
778 goes into 6430 8 times with a remainder of 206.
The next digit of our result is 8. 
Result so far: 5648.0
If we take 6224 away from 6430, we end up with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 778

On to step 8:
The number 778 fits into 2061 2 times, leaving a remainder of 505.
The next digit of our result is 2. 
Result so far: 56482.0
Subtract 1556 from 2061 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 9:
If we divide 5050 by 778, we get 6 and a remainder of 382.
Put 6 as the next digit of the answer. 
Result so far: 56482.6
Subtracting 4668 from 5050 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 10:
When dividing 3820 by 778, we get 4 with a remainder of 708.
The next digit of our result is 4. 
Result so far: 56482.64
If we subtract 3112 from 3820, we get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 11:
If we divide 7080 by 778, we get 9 and a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 56482.649
The remainder is 78 after subtracting 7002 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
When dividing 780 by 778, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 56482.6491
Deduct 778 from 780 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
778 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 56482.6491
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
778 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 56482.6491
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 56482.6491, with a leftover of 2e-05.
