77820472 ÷ 916 
The aim is to understand the frequency of 916 in 77820472.

Moving on to step 1:
When dividing 7 by 916, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 916

Moving on to step 2:
916 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 916

On to step 3:
916 goes into 778 0 times with a remainder of 778.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 778 after subtracting 0 from 778.
Include the next digit (2) from the dividend after 778, then repeat: 7782 / 916

Moving on to step 4:
916 goes into 7782 8 times with a remainder of 454.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7328 from 7782 to get 454.
Append the next digit (0) from the dividend to 454 and continue with: 4540 / 916

Advancing to step 5:
If we divide 4540 by 916, we get 4 and a remainder of 876.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 876 after subtracting 3664 from 4540.
Take the next digit (4) from the dividend and append it to 876, then repeat: 8764 / 916

Moving on to step 6:
The number 916 fits into 8764 9 times, leaving a remainder of 520.
Use 9 as the next digit of our solution. 
Result so far: 849.0
Subtract 8244 from 8764 to get 520.
Grab the next digit (7) from the dividend, add it to 520, then carry on: 5207 / 916

Moving on to step 7:
If we divide 5207 by 916, we get 5 and a remainder of 627.
Put 5 as the next digit of the answer. 
Result so far: 8495.0
Deduct 4580 from 5207 and we're left with 627.
Fetch the next digit (2) from the dividend, attach it to 627 and continue: 6272 / 916

Going ahead to step 8:
916 can be fit into 6272 6 times, resulting in a remainder of 776.
Write down 6 as next digit of the result. 
Result so far: 84956.0
If we take 5496 away from 6272, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 9:
When dividing 7760 by 916, we get 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 84956.8
If we subtract 7328 from 7760, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 10:
If we divide 4320 by 916, we get 4 and a remainder of 656.
The number 4 becomes the next digit in our result. 
Result so far: 84956.84
The remainder is 656 after subtracting 3664 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 11:
If we divide 6560 by 916, we get 7 and a remainder of 148.
The next digit of our result is 7. 
Result so far: 84956.847
Deduct 6412 from 6560 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
1480 divided by 916 is 1 with a remainder of 564.
Write down 1 as next digit of the result. 
Result so far: 84956.8471
Subtract 916 from 1480 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 13:
5640 divided by 916 is 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 84956.84716
If we subtract 5496 from 5640, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 14:
1440 divided by 916 is 1 with a remainder of 524.
Put 1 as the next digit of the answer. 
Result so far: 84956.847161
Subtracting 916 from 1440 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 15:
When dividing 5240 by 916, we get 5 with a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 84956.8471615
Subtracting 4580 from 5240 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 16:
The number 916 fits into 6600 7 times, leaving a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 84956.84716157
If we take 6412 away from 6600, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The quotient of the division is 84956.84716157, and the remainder is 1.88e-07.
