We're dividing 69872701 by 423 
The aim is to understand the frequency of 423 in 69872701.

Let's proceed to step 1:
If we divide 6 by 423, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 423

Step 2:
The number 423 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 423

Step 3:
698 divided by 423 is 1 with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 423 from 698 leaves us with 275.
Bring next digit (7) of the dividend behind the 275 and repeat the process: 2757 / 423

Advancing to step 4:
If we divide 2757 by 423, we get 6 and a remainder of 219.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 219 after subtracting 2538 from 2757.
Append the next digit (2) from the dividend to 219 and continue with: 2192 / 423

Going ahead to step 5:
The number 423 fits into 2192 5 times, leaving a remainder of 77.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Subtracting 2115 from 2192 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 423

On to step 6:
The number 423 fits into 777 1 times, leaving a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 1651.0
Subtract 423 from 777 to get 354.
Take the next digit (0) from the dividend and append it to 354, then repeat: 3540 / 423

On to step 7:
The number 423 fits into 3540 8 times, leaving a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 16518.0
Subtracting 3384 from 3540 leaves us with 156.
Take the next digit (1) from the dividend and append it to 156, then repeat: 1561 / 423

Advancing to step 8:
423 can be fit into 1561 3 times, resulting in a remainder of 292.
Record the quotient 3 as the next digit in the result. 
Result so far: 165183.0
Subtract 1269 from 1561 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 9:
2920 divided by 423 is 6 with a remainder of 382.
The next digit of our result is 6. 
Result so far: 165183.6
Subtract 2538 from 2920 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
423 goes into 3820 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 165183.69
Subtracting 3807 from 3820 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
423 goes into 130 0 times with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 165183.69
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
423 can be fit into 1300 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 165183.6903
If we subtract 1269 from 1300, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
The number 423 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 165183.6903
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 14:
423 goes into 3100 7 times with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 165183.690307
Subtract 2961 from 3100 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 15:
423 can be fit into 1390 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 165183.6903073
The remainder is 121 after subtracting 1269 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 16:
If we divide 1210 by 423, we get 2 and a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 165183.69030732
If we take 846 away from 1210, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

In conclusion, the division gives 165183.69030732 with a balance of 3.64e-07.
