873662 ÷ 69 
The aim is to understand the frequency of 69 in 873662.

Advancing to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 69

Advancing to step 2:
If we divide 87 by 69, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 69 from 87 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 69

Moving on to step 3:
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: 12.0
If we take 138 away from 183, we end up with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 69

On to step 4:
The number 69 fits into 456 6 times, leaving a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we subtract 414 from 456, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 69

Advancing to step 5:
If we divide 426 by 69, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1266.0
Subtracting 414 from 426 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 69

Advancing to step 6:
When dividing 122 by 69, we get 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 12661.0
If we take 69 away from 122, we end up 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.

On to step 7:
69 goes into 530 7 times with a remainder of 47.
The next digit of our result is 7. 
Result so far: 12661.7
If we take 483 away from 530, we end up 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 8:
470 divided by 69 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 12661.76
If we take 414 away from 470, we end up 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.

Let's proceed to step 9:
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: 12661.768
Subtracting 552 from 560 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
69 goes into 80 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 12661.7681
Subtracting 69 from 80 leaves us 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.

Going ahead to step 11:
69 goes into 110 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 12661.76811
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.

After the division, we end up with 12661.76811 and a remainder of 4.1e-05.
