777398 ÷ 69 
The aim is to understand the frequency of 69 in 777398.

Moving on to step 1:
When dividing 7 by 69, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 69

Let's proceed to step 2:
69 goes into 77 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 69 from 77.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 69

Let's proceed to step 3:
69 goes into 87 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 69 from 87, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 69

Moving on to step 4:
The number 69 fits into 183 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Deduct 138 from 183 and we're left with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 69

On to step 5:
The number 69 fits into 459 6 times, leaving a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
Subtracting 414 from 459 leaves us with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 69

Advancing to step 6:
If we divide 458 by 69, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 11266.0
Deduct 414 from 458 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
69 can be fit into 440 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 11266.6
Deduct 414 from 440 and we're left 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.

Step 8:
69 goes into 260 3 times with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 11266.63
The remainder is 53 after subtracting 207 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
530 divided by 69 is 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 11266.637
Subtracting 483 from 530 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
69 goes into 470 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 11266.6376
Subtracting 414 from 470 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
69 can be fit into 560 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11266.63768
If we subtract 552 from 560, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 69, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 11266.637681
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
If we divide 110 by 69, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 11266.6376811
Deduct 69 from 110 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 11266.6376811, with a leftover of 4.1e-07.
