78917964 ÷ 705 
The aim is to understand the frequency of 705 in 78917964.

Step 1:
If we divide 7 by 705, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 705

Moving on to step 2:
When dividing 78 by 705, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 705

Going ahead to step 3:
If we divide 789 by 705, we get 1 and a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 84 after subtracting 705 from 789.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 705

Moving on to step 4:
If we divide 841 by 705, we get 1 and a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 705 away from 841, we end up with 136.
Take the next digit (7) from the dividend and append it to 136, then repeat: 1367 / 705

Step 5:
When dividing 1367 by 705, we get 1 with a remainder of 662.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we take 705 away from 1367, we end up with 662.
Bring next digit (9) of the dividend behind the 662 and repeat the process: 6629 / 705

Step 6:
6629 divided by 705 is 9 with a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 1119.0
If we subtract 6345 from 6629, we get 284.
Grab the next digit (6) from the dividend, add it to 284, then carry on: 2846 / 705

Going ahead to step 7:
2846 divided by 705 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 11194.0
If we take 2820 away from 2846, we end up with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 705

On to step 8:
When dividing 264 by 705, we get 0 with a remainder of 264.
Write down 0 as next digit of the result. 
Result so far: 111940.0
Deduct 0 from 264 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 9:
705 can be fit into 2640 3 times, resulting in a remainder of 525.
Write down 3 as next digit of the result. 
Result so far: 111940.3
The remainder is 525 after subtracting 2115 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 10:
The number 705 fits into 5250 7 times, leaving a remainder of 315.
Record the quotient 7 as the next digit in the result. 
Result so far: 111940.37
Deduct 4935 from 5250 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 11:
705 can be fit into 3150 4 times, resulting in a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 111940.374
Subtracting 2820 from 3150 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 12:
If we divide 3300 by 705, we get 4 and a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 111940.3744
Subtracting 2820 from 3300 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 111940.3744, and the remainder is 0.0048.
