We're dividing 4001300 by 778 
The aim is to understand the frequency of 778 in 4001300.

Step 1:
The number 778 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 778

On to step 2:
778 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 778

Going ahead to step 3:
If we divide 400 by 778, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Take the next digit (1) from the dividend and append it to 400, then repeat: 4001 / 778

Advancing to step 4:
778 can be fit into 4001 5 times, resulting in a remainder of 111.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3890 away from 4001, we end up with 111.
Take the next digit (3) from the dividend and append it to 111, then repeat: 1113 / 778

Advancing to step 5:
When dividing 1113 by 778, we get 1 with a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 778 from 1113 leaves us with 335.
Include the next digit (0) from the dividend after 335, then repeat: 3350 / 778

On to step 6:
The number 778 fits into 3350 4 times, leaving a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
Subtracting 3112 from 3350 leaves us with 238.
Append the next digit (0) from the dividend to 238 and continue with: 2380 / 778

Moving on to step 7:
The number 778 fits into 2380 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 5143.0
If we take 2334 away from 2380, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 778, we get 0 with a remainder of 460.
The next digit of our result is 0. 
Result so far: 5143.0
If we subtract 0 from 460, 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 9:
When dividing 4600 by 778, we get 5 with a remainder of 710.
Record the quotient 5 as the next digit in the result. 
Result so far: 5143.05
If we subtract 3890 from 4600, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 10:
When dividing 7100 by 778, we get 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 5143.059
Subtracting 7002 from 7100 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
When dividing 980 by 778, we get 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 5143.0591
The remainder is 202 after subtracting 778 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 12:
778 goes into 2020 2 times with a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 5143.05912
Deduct 1556 from 2020 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 13:
4640 divided by 778 is 5 with a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 5143.059125
Deduct 3890 from 4640 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
7500 divided by 778 is 9 with a remainder of 498.
Write down 9 as next digit of the result. 
Result so far: 5143.0591259
Deduct 7002 from 7500 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 15:
When dividing 4980 by 778, we get 6 with a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 5143.05912596
If we take 4668 away from 4980, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 5143.05912596 with a remainder of 3.12e-07.
