Let's divide 75558100 by 780
The aim is to understand the frequency of 780 in 75558100.

Going ahead to step 1:
780 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 780

On to step 2:
The number 780 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 780

Let's proceed to step 3:
The number 780 fits into 755 0 times, leaving a remainder of 755.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 755 after subtracting 0 from 755.
Take the next digit (5) from the dividend and append it to 755, then repeat: 7555 / 780

Moving on to step 4:
If we divide 7555 by 780, we get 9 and a remainder of 535.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7020 from 7555 to get 535.
Fetch the next digit (8) from the dividend, attach it to 535 and continue: 5358 / 780

Advancing to step 5:
5358 divided by 780 is 6 with a remainder of 678.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 4680 from 5358, we get 678.
Bring next digit (1) of the dividend behind the 678 and repeat the process: 6781 / 780

On to step 6:
780 goes into 6781 8 times with a remainder of 541.
The number 8 becomes the next digit in our result. 
Result so far: 968.0
If we subtract 6240 from 6781, we get 541.
Fetch the next digit (0) from the dividend, attach it to 541 and continue: 5410 / 780

Moving on to step 7:
When dividing 5410 by 780, we get 6 with a remainder of 730.
Put 6 as the next digit of the answer. 
Result so far: 9686.0
If we subtract 4680 from 5410, we get 730.
Fetch the next digit (0) from the dividend, attach it to 730 and continue: 7300 / 780

Moving on to step 8:
The number 780 fits into 7300 9 times, leaving a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 96869.0
Subtracting 7020 from 7300 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 9:
If we divide 2800 by 780, we get 3 and a remainder of 460.
Use 3 as the next digit of our solution. 
Result so far: 96869.3
Subtracting 2340 from 2800 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
780 can be fit into 4600 5 times, resulting in a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 96869.35
Subtracting 3900 from 4600 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 11:
7000 divided by 780 is 8 with a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 96869.358
Subtract 6240 from 7000 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 12:
7600 divided by 780 is 9 with a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 96869.3589
If we subtract 7020 from 7600, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 13:
780 goes into 5800 7 times with a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 96869.35897
The remainder is 340 after subtracting 5460 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 14:
780 goes into 3400 4 times with a remainder of 280.
The next digit of our result is 4. 
Result so far: 96869.358974
If we take 3120 away from 3400, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
If we divide 2800 by 780, we get 3 and a remainder of 460.
The next digit of our result is 3. 
Result so far: 96869.3589743
If we subtract 2340 from 2800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 16:
If we divide 4600 by 780, we get 5 and a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 96869.35897435
If we subtract 3900 from 4600, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 96869.35897435, and the remainder is 7e-07.
