We look at the division of 55800840 by 778 
The aim is to understand the frequency of 778 in 55800840.

Let's proceed to step 1:
If we divide 5 by 778, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 778

Let's proceed to step 2:
55 divided by 778 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 778

Going ahead to step 3:
778 goes into 558 0 times with a remainder of 558.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 558 to get 558.
Include the next digit (0) from the dividend after 558, then repeat: 5580 / 778

Advancing to step 4:
778 can be fit into 5580 7 times, resulting in a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 5446 from 5580 to get 134.
Append the next digit (0) from the dividend to 134 and continue with: 1340 / 778

Step 5:
The number 778 fits into 1340 1 times, leaving a remainder of 562.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we take 778 away from 1340, we end up with 562.
Append the next digit (8) from the dividend to 562 and continue with: 5628 / 778

Advancing to step 6:
When dividing 5628 by 778, we get 7 with a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 717.0
Subtracting 5446 from 5628 leaves us with 182.
Fetch the next digit (4) from the dividend, attach it to 182 and continue: 1824 / 778

Step 7:
When dividing 1824 by 778, we get 2 with a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 7172.0
Deduct 1556 from 1824 and we're left with 268.
Grab the next digit (0) from the dividend, add it to 268, then carry on: 2680 / 778

Advancing to step 8:
778 can be fit into 2680 3 times, resulting in a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 71723.0
If we take 2334 away from 2680, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 9:
3460 divided by 778 is 4 with a remainder of 348.
The number 4 becomes the next digit in our result. 
Result so far: 71723.4
The remainder is 348 after subtracting 3112 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 10:
The number 778 fits into 3480 4 times, leaving a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 71723.44
Deduct 3112 from 3480 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 71723.44, and the remainder is 0.368.
