We're dividing 601343 by 77 
The aim is to understand the frequency of 77 in 601343.

Let's proceed to step 1:
6 divided by 77 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 77

Advancing to step 2:
77 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 77

On to step 3:
77 can be fit into 601 7 times, resulting in a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 539 from 601, we get 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 77

On to step 4:
77 can be fit into 623 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 616 from 623, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 77

Let's proceed to step 5:
74 divided by 77 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 77

Step 6:
When dividing 743 by 77, we get 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 7809.0
Subtract 693 from 743 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 77, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 7809.6
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 77, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 7809.64
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
If we divide 720 by 77, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 7809.649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
If we divide 270 by 77, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 7809.6493
If we take 231 away from 270, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7809.64935
Deduct 385 from 390 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
When dividing 50 by 77, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7809.64935
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
If we divide 500 by 77, we get 6 and a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 7809.6493506
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
The number 77 fits into 380 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 7809.64935064
If we subtract 308 from 380, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 7809.64935064 and a remainder of 7.2e-08.
