Let's divide 761484 by 77
The aim is to understand the frequency of 77 in 761484.

Going ahead to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 77

Going ahead to step 2:
77 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 77

Advancing to step 3:
When dividing 761 by 77, we get 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 693 from 761 leaves us with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 77

Advancing to step 4:
The number 77 fits into 684 8 times, leaving a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 68 after subtracting 616 from 684.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 77

Going ahead to step 5:
77 can be fit into 688 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 988.0
If we subtract 616 from 688, we get 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 77

Step 6:
724 divided by 77 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9889.0
Deduct 693 from 724 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
77 goes into 310 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9889.4
If we take 308 away from 310, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 77, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 9889.4
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 77, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 9889.402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
77 can be fit into 460 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 9889.4025
Subtracting 385 from 460 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.

Step 11:
When dividing 750 by 77, we get 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 9889.40259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
77 goes into 570 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 9889.402597
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9889.4025974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
77 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9889.4025974
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9889.4025974 with a remainder of 2e-08.
