Let's divide 721619 by 69
The aim is to understand the frequency of 69 in 721619.

Step 1:
69 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 69

Going ahead to step 2:
If we divide 72 by 69, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 69 from 72 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 69

Step 3:
69 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 31, we get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 69

Advancing to step 4:
The number 69 fits into 316 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 276 from 316, we get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 69

Going ahead to step 5:
If we divide 401 by 69, we get 5 and a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
If we take 345 away from 401, we end up with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 69

Moving on to step 6:
The number 69 fits into 569 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 10458.0
If we take 552 away from 569, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
If we divide 170 by 69, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10458.2
The remainder is 32 after subtracting 138 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
69 goes into 320 4 times with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 10458.24
Subtract 276 from 320 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
69 can be fit into 440 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 10458.246
If we subtract 414 from 440, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
69 can be fit into 260 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 10458.2463
Deduct 207 from 260 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
The number 69 fits into 530 7 times, leaving a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 10458.24637
Subtract 483 from 530 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
The number 69 fits into 470 6 times, leaving a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 10458.246376
If we subtract 414 from 470, we get 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 13:
If we divide 560 by 69, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10458.2463768
The remainder is 8 after subtracting 552 from 560.
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 14:
69 can be fit into 80 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 10458.24637681
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 10458.24637681, with a leftover of 1.1e-08.
