We look at the division of 641714 by 77 
The aim is to understand the frequency of 77 in 641714.

On to step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 77

Advancing to step 2:
64 divided by 77 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 77

Let's proceed to step 3:
The number 77 fits into 641 8 times, leaving a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 616 from 641 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 77

Moving on to step 4:
The number 77 fits into 257 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 26 after subtracting 231 from 257.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 77

Moving on to step 5:
77 can be fit into 261 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 833.0
If we take 231 away from 261, we end up with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 77

Let's proceed to step 6:
If we divide 304 by 77, we get 3 and a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 8333.0
The remainder is 73 after subtracting 231 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8333.9
Deduct 693 from 730 and we're left 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 8:
If we divide 370 by 77, we get 4 and a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 8333.94
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
620 divided by 77 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8333.948
If we take 616 away from 620, we end up 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.

Let's proceed to step 10:
40 divided by 77 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8333.948
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 11:
400 divided by 77 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8333.94805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
77 can be fit into 150 1 times, resulting in a remainder of 73.
The next digit of our result is 1. 
Result so far: 8333.948051
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.

Going ahead to step 13:
When dividing 730 by 77, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8333.9480519
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.

Let's proceed to step 14:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 8333.94805194
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.

The final result is 8333.94805194 with a remainder of 6.2e-08.
