We look at the division of 77855121 by 705 
The aim is to understand the frequency of 705 in 77855121.

On to step 1:
7 divided by 705 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 705

Let's proceed to step 2:
77 divided by 705 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 705

Going ahead to step 3:
705 can be fit into 778 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 705 from 778 leaves us with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 705

Going ahead to step 4:
705 goes into 735 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 705 from 735 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 705

On to step 5:
305 divided by 705 is 0 with a remainder of 305.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 305 to get 305.
Append the next digit (1) from the dividend to 305 and continue with: 3051 / 705

On to step 6:
The number 705 fits into 3051 4 times, leaving a remainder of 231.
The number 4 becomes the next digit in our result. 
Result so far: 1104.0
If we subtract 2820 from 3051, we get 231.
Include the next digit (2) from the dividend after 231, then repeat: 2312 / 705

Step 7:
The number 705 fits into 2312 3 times, leaving a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 11043.0
Subtracting 2115 from 2312 leaves us with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 705

Step 8:
1971 divided by 705 is 2 with a remainder of 561.
Write down 2 as next digit of the result. 
Result so far: 110432.0
Subtract 1410 from 1971 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Advancing to step 9:
If we divide 5610 by 705, we get 7 and a remainder of 675.
Write down 7 as next digit of the result. 
Result so far: 110432.7
Subtract 4935 from 5610 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 10:
6750 divided by 705 is 9 with a remainder of 405.
Use 9 as the next digit of our solution. 
Result so far: 110432.79
Subtract 6345 from 6750 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 11:
4050 divided by 705 is 5 with a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 110432.795
Subtracting 3525 from 4050 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 12:
5250 divided by 705 is 7 with a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 110432.7957
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.

Let's proceed to step 13:
The number 705 fits into 3150 4 times, leaving a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 110432.79574
Subtract 2820 from 3150 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 14:
If we divide 3300 by 705, we get 4 and a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 110432.795744
Deduct 2820 from 3300 and we're left 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.

After the division, we end up with 110432.795744 and a remainder of 4.8e-05.
