67215892 ÷ 770 
The aim is to understand the frequency of 770 in 67215892.

Advancing to step 1:
6 divided by 770 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 770

Advancing to step 2:
If we divide 67 by 770, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 770

Moving on to step 3:
770 can be fit into 672 0 times, resulting in a remainder of 672.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 672 and we're left with 672.
Bring next digit (1) of the dividend behind the 672 and repeat the process: 6721 / 770

On to step 4:
If we divide 6721 by 770, we get 8 and a remainder of 561.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6160 from 6721, we get 561.
Fetch the next digit (5) from the dividend, attach it to 561 and continue: 5615 / 770

Advancing to step 5:
When dividing 5615 by 770, we get 7 with a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 225 after subtracting 5390 from 5615.
Include the next digit (8) from the dividend after 225, then repeat: 2258 / 770

Advancing to step 6:
770 can be fit into 2258 2 times, resulting in a remainder of 718.
Record the quotient 2 as the next digit in the result. 
Result so far: 872.0
Deduct 1540 from 2258 and we're left with 718.
Take the next digit (9) from the dividend and append it to 718, then repeat: 7189 / 770

Moving on to step 7:
If we divide 7189 by 770, we get 9 and a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 8729.0
If we subtract 6930 from 7189, we get 259.
Take the next digit (2) from the dividend and append it to 259, then repeat: 2592 / 770

On to step 8:
The number 770 fits into 2592 3 times, leaving a remainder of 282.
The next digit of our result is 3. 
Result so far: 87293.0
Deduct 2310 from 2592 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 9:
The number 770 fits into 2820 3 times, leaving a remainder of 510.
Record the quotient 3 as the next digit in the result. 
Result so far: 87293.3
Deduct 2310 from 2820 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
When dividing 5100 by 770, we get 6 with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 87293.36
The remainder is 480 after subtracting 4620 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
If we divide 4800 by 770, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 87293.366
If we take 4620 away from 4800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 87293.366 with a remainder of 0.018.
