We look at the division of 91260529 by 705 
The aim is to understand the frequency of 705 in 91260529.

Going ahead to step 1:
The number 705 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 705

Step 2:
91 divided by 705 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 705

On to step 3:
705 can be fit into 912 1 times, resulting in a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 705 from 912, we get 207.
Grab the next digit (6) from the dividend, add it to 207, then carry on: 2076 / 705

Let's proceed to step 4:
705 can be fit into 2076 2 times, resulting in a remainder of 666.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1410 from 2076 leaves us with 666.
Append the next digit (0) from the dividend to 666 and continue with: 6660 / 705

Moving on to step 5:
If we divide 6660 by 705, we get 9 and a remainder of 315.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Deduct 6345 from 6660 and we're left with 315.
Take the next digit (5) from the dividend and append it to 315, then repeat: 3155 / 705

On to step 6:
When dividing 3155 by 705, we get 4 with a remainder of 335.
Record the quotient 4 as the next digit in the result. 
Result so far: 1294.0
If we subtract 2820 from 3155, we get 335.
Grab the next digit (2) from the dividend, add it to 335, then carry on: 3352 / 705

Moving on to step 7:
3352 divided by 705 is 4 with a remainder of 532.
The next digit of our result is 4. 
Result so far: 12944.0
Deduct 2820 from 3352 and we're left with 532.
Include the next digit (9) from the dividend after 532, then repeat: 5329 / 705

On to step 8:
705 goes into 5329 7 times with a remainder of 394.
Record the quotient 7 as the next digit in the result. 
Result so far: 129447.0
Subtracting 4935 from 5329 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
705 can be fit into 3940 5 times, resulting in a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 129447.5
Deduct 3525 from 3940 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 10:
The number 705 fits into 4150 5 times, leaving a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 129447.55
The remainder is 625 after subtracting 3525 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

The final result is 129447.55 with a remainder of 0.625.
