70186780 divided by 775 
The aim is to understand the frequency of 775 in 70186780.

On to step 1:
7 divided by 775 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 775

Going ahead to step 2:
When dividing 70 by 775, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 775

Going ahead to step 3:
775 can be fit into 701 0 times, resulting in a remainder of 701.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 701 leaves us with 701.
Include the next digit (8) from the dividend after 701, then repeat: 7018 / 775

Advancing to step 4:
When dividing 7018 by 775, we get 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 6975 from 7018, we get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 775

Going ahead to step 5:
775 goes into 436 0 times with a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 436 to get 436.
Fetch the next digit (7) from the dividend, attach it to 436 and continue: 4367 / 775

On to step 6:
The number 775 fits into 4367 5 times, leaving a remainder of 492.
The number 5 becomes the next digit in our result. 
Result so far: 905.0
Deduct 3875 from 4367 and we're left with 492.
Include the next digit (8) from the dividend after 492, then repeat: 4928 / 775

On to step 7:
775 goes into 4928 6 times with a remainder of 278.
Record the quotient 6 as the next digit in the result. 
Result so far: 9056.0
If we subtract 4650 from 4928, we get 278.
Bring next digit (0) of the dividend behind the 278 and repeat the process: 2780 / 775

Let's proceed to step 8:
775 can be fit into 2780 3 times, resulting in a remainder of 455.
Put 3 as the next digit of the answer. 
Result so far: 90563.0
Deduct 2325 from 2780 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 9:
The number 775 fits into 4550 5 times, leaving a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 90563.5
The remainder is 675 after subtracting 3875 from 4550.
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:
775 can be fit into 6750 8 times, resulting in a remainder of 550.
Use 8 as the next digit of our solution. 
Result so far: 90563.58
If we take 6200 away from 6750, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
If we divide 5500 by 775, we get 7 and a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 90563.587
Subtracting 5425 from 5500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
750 divided by 775 is 0 with a remainder of 750.
The next digit of our result is 0. 
Result so far: 90563.587
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 13:
The number 775 fits into 7500 9 times, leaving a remainder of 525.
Put 9 as the next digit of the answer. 
Result so far: 90563.58709
Subtract 6975 from 7500 to get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 14:
If we divide 5250 by 775, we get 6 and a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 90563.587096
If we subtract 4650 from 5250, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 15:
775 goes into 6000 7 times with a remainder of 575.
Write down 7 as next digit of the result. 
Result so far: 90563.5870967
Subtracting 5425 from 6000 leaves us with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 16:
If we divide 5750 by 775, we get 7 and a remainder of 325.
Write down 7 as next digit of the result. 
Result so far: 90563.58709677
Subtract 5425 from 5750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 90563.58709677 and a remainder of 3.25e-07.
