7207410 divided by 778 
The aim is to understand the frequency of 778 in 7207410.

Step 1:
When dividing 7 by 778, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 778

Step 2:
778 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 778

On to step 3:
778 can be fit into 720 0 times, resulting in a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 720 leaves us with 720.
Bring next digit (7) of the dividend behind the 720 and repeat the process: 7207 / 778

Moving on to step 4:
If we divide 7207 by 778, we get 9 and a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7002 from 7207 to get 205.
Grab the next digit (4) from the dividend, add it to 205, then carry on: 2054 / 778

Going ahead to step 5:
If we divide 2054 by 778, we get 2 and a remainder of 498.
Write down 2 as next digit of the result. 
Result so far: 92.0
Deduct 1556 from 2054 and we're left with 498.
Take the next digit (1) from the dividend and append it to 498, then repeat: 4981 / 778

Advancing to step 6:
If we divide 4981 by 778, we get 6 and a remainder of 313.
Use 6 as the next digit of our solution. 
Result so far: 926.0
If we subtract 4668 from 4981, we get 313.
Fetch the next digit (0) from the dividend, attach it to 313 and continue: 3130 / 778

Going ahead to step 7:
778 can be fit into 3130 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 9264.0
Deduct 3112 from 3130 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
The number 778 fits into 180 0 times, leaving a remainder of 180.
The next digit of our result is 0. 
Result so far: 9264.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
The number 778 fits into 1800 2 times, leaving a remainder of 244.
The next digit of our result is 2. 
Result so far: 9264.02
Subtract 1556 from 1800 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
2440 divided by 778 is 3 with a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 9264.023
The remainder is 106 after subtracting 2334 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 11:
1060 divided by 778 is 1 with a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 9264.0231
If we take 778 away from 1060, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 12:
If we divide 2820 by 778, we get 3 and a remainder of 486.
Use 3 as the next digit of our solution. 
Result so far: 9264.02313
Subtracting 2334 from 2820 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 13:
778 can be fit into 4860 6 times, resulting in a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 9264.023136
If we subtract 4668 from 4860, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
778 can be fit into 1920 2 times, resulting in a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 9264.0231362
Subtracting 1556 from 1920 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 15:
3640 divided by 778 is 4 with a remainder of 528.
Use 4 as the next digit of our solution. 
Result so far: 9264.02313624
Subtracting 3112 from 3640 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final outcome is 9264.02313624, with a leftover of 5.28e-07.
