We divide 850299 by 77
The aim is to understand the frequency of 77 in 850299.

Let's proceed to step 1:
8 divided by 77 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 77

Going ahead to step 2:
85 divided by 77 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 85 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 77

Moving on to step 3:
When dividing 80 by 77, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 77 from 80 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 77

Step 4:
77 can be fit into 32 0 times, resulting in a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 32 to get 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 77

Moving on to step 5:
If we divide 329 by 77, we get 4 and a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 1104.0
If we subtract 308 from 329, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 77

Going ahead to step 6:
The number 77 fits into 219 2 times, leaving a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 11042.0
If we subtract 154 from 219, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
If we divide 650 by 77, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 11042.8
If we subtract 616 from 650, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 77, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11042.84
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 77 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11042.844
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 11042.844 with a remainder of 0.0012.
