We look at the division of 69558065 by 778 
The aim is to understand the frequency of 778 in 69558065.

Let's proceed to step 1:
The number 778 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 778

On to step 2:
778 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (5) from the dividend, attach it to 69 and continue: 695 / 778

Moving on to step 3:
The number 778 fits into 695 0 times, leaving a remainder of 695.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 695, we end up with 695.
Bring next digit (5) of the dividend behind the 695 and repeat the process: 6955 / 778

Let's proceed to step 4:
If we divide 6955 by 778, we get 8 and a remainder of 731.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6224 from 6955 and we're left with 731.
Grab the next digit (8) from the dividend, add it to 731, then carry on: 7318 / 778

Advancing to step 5:
If we divide 7318 by 778, we get 9 and a remainder of 316.
The next digit of our result is 9. 
Result so far: 89.0
If we take 7002 away from 7318, we end up with 316.
Bring next digit (0) of the dividend behind the 316 and repeat the process: 3160 / 778

Step 6:
778 goes into 3160 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 894.0
The remainder is 48 after subtracting 3112 from 3160.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 778

On to step 7:
778 goes into 486 0 times with a remainder of 486.
Use 0 as the next digit of our solution. 
Result so far: 8940.0
If we take 0 away from 486, we end up with 486.
Grab the next digit (5) from the dividend, add it to 486, then carry on: 4865 / 778

Let's proceed to step 8:
When dividing 4865 by 778, we get 6 with a remainder of 197.
The next digit of our result is 6. 
Result so far: 89406.0
Deduct 4668 from 4865 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
1970 divided by 778 is 2 with a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 89406.2
Deduct 1556 from 1970 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 10:
778 goes into 4140 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 89406.25
Subtracting 3890 from 4140 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
When dividing 2500 by 778, we get 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 89406.253
The remainder is 166 after subtracting 2334 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 12:
If we divide 1660 by 778, we get 2 and a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 89406.2532
If we take 1556 away from 1660, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
1040 divided by 778 is 1 with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 89406.25321
If we take 778 away from 1040, 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.

Going ahead to step 14:
When dividing 2620 by 778, we get 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 89406.253213
If we take 2334 away from 2620, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 15:
When dividing 2860 by 778, we get 3 with a remainder of 526.
Use 3 as the next digit of our solution. 
Result so far: 89406.2532133
Deduct 2334 from 2860 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

After the division, we end up with 89406.2532133 and a remainder of 5.26e-06.
