We look at the division of 248475 by 77 
The aim is to understand the frequency of 77 in 248475.

Going ahead to step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 77

Advancing to step 2:
If we divide 24 by 77, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 77

Moving on to step 3:
248 divided by 77 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 231 from 248, we get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 77

Let's proceed to step 4:
When dividing 174 by 77, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 154 from 174 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 77

On to step 5:
77 goes into 207 2 times with a remainder of 53.
The next digit of our result is 2. 
Result so far: 322.0
Subtracting 154 from 207 leaves us with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 77

Step 6:
The number 77 fits into 535 6 times, leaving a remainder of 73.
The next digit of our result is 6. 
Result so far: 3226.0
Deduct 462 from 535 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
77 can be fit into 730 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 3226.9
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
If we divide 370 by 77, we get 4 and a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 3226.94
If we subtract 308 from 370, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
If we divide 620 by 77, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3226.948
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 77, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3226.948
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
The number 77 fits into 400 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3226.94805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
The number 77 fits into 150 1 times, leaving a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 3226.948051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 3226.9480519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
77 goes into 370 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 3226.94805194
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 3226.94805194 with a remaining 6.2e-08.
