Let's divide 1977649 by 69
The aim is to understand the frequency of 69 in 1977649.

On to step 1:
1 divided by 69 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 69

Going ahead to step 2:
When dividing 19 by 69, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 69

Moving on to step 3:
If we divide 197 by 69, we get 2 and a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 138 from 197, we get 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 69

Let's proceed to step 4:
The number 69 fits into 597 8 times, leaving a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 45 after subtracting 552 from 597.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 69

Going ahead to step 5:
69 goes into 456 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 286.0
Deduct 414 from 456 and we're left with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 69

Going ahead to step 6:
When dividing 424 by 69, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 2866.0
If we take 414 away from 424, we end up with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 69

On to step 7:
109 divided by 69 is 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 28661.0
Subtracting 69 from 109 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.

Advancing to step 8:
If we divide 400 by 69, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 28661.5
Deduct 345 from 400 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
550 divided by 69 is 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 28661.57
Subtracting 483 from 550 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
If we divide 670 by 69, we get 9 and a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 28661.579
If we subtract 621 from 670, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 11:
If we divide 490 by 69, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 28661.5797
If we take 483 away from 490, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
69 can be fit into 70 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 28661.57971
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
69 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 28661.57971
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
The number 69 fits into 100 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 28661.5797101
The remainder is 31 after subtracting 69 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 15:
When dividing 310 by 69, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 28661.57971014
Subtracting 276 from 310 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 28661.57971014 with a remainder of 3.4e-08.
