Let's divide 61517042 by 77
The aim is to understand the frequency of 77 in 61517042.

Advancing to step 1:
If we divide 6 by 77, we get 0 and 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.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 77

Advancing to step 2:
If we divide 61 by 77, we get 0 and a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 77

Moving on to step 3:
When dividing 615 by 77, we get 7 with a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 76 after subtracting 539 from 615.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 77

Moving on to step 4:
77 goes into 761 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 693 from 761 to get 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 77

Let's proceed to step 5:
77 goes into 687 8 times with a remainder of 71.
The next digit of our result is 8. 
Result so far: 798.0
If we subtract 616 from 687, we get 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 77

On to step 6:
710 divided by 77 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 7989.0
The remainder is 17 after subtracting 693 from 710.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 77

Step 7:
77 goes into 174 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 79892.0
If we subtract 154 from 174, we get 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 77

Step 8:
If we divide 202 by 77, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 798922.0
Subtracting 154 from 202 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
77 can be fit into 480 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 798922.6
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
77 can be fit into 180 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 798922.62
Subtracting 154 from 180 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
If we divide 260 by 77, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 798922.623
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
77 can be fit into 290 3 times, resulting in a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 798922.6233
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 798922.6233 with a remainder of 0.00059.
