11980962 ÷ 423 
The aim is to understand the frequency of 423 in 11980962.

Advancing to step 1:
If we divide 1 by 423, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 423

On to step 2:
If we divide 11 by 423, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 423

Step 3:
The number 423 fits into 119 0 times, leaving a remainder of 119.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 119 leaves us with 119.
Append the next digit (8) from the dividend to 119 and continue with: 1198 / 423

Moving on to step 4:
423 goes into 1198 2 times with a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 846 away from 1198, we end up with 352.
Take the next digit (0) from the dividend and append it to 352, then repeat: 3520 / 423

Advancing to step 5:
423 can be fit into 3520 8 times, resulting in a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 3384 from 3520 to get 136.
Fetch the next digit (9) from the dividend, attach it to 136 and continue: 1369 / 423

Advancing to step 6:
423 goes into 1369 3 times with a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 283.0
Deduct 1269 from 1369 and we're left with 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 423

Moving on to step 7:
1006 divided by 423 is 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 2832.0
The remainder is 160 after subtracting 846 from 1006.
Take the next digit (2) from the dividend and append it to 160, then repeat: 1602 / 423

Step 8:
If we divide 1602 by 423, we get 3 and a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 28323.0
The remainder is 333 after subtracting 1269 from 1602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 9:
423 goes into 3330 7 times with a remainder of 369.
Record the quotient 7 as the next digit in the result. 
Result so far: 28323.7
If we subtract 2961 from 3330, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 10:
When dividing 3690 by 423, we get 8 with a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 28323.78
Subtract 3384 from 3690 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
When dividing 3060 by 423, we get 7 with a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 28323.787
Subtract 2961 from 3060 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 12:
423 goes into 990 2 times with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 28323.7872
Deduct 846 from 990 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
423 can be fit into 1440 3 times, resulting in a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 28323.78723
Subtracting 1269 from 1440 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 14:
1710 divided by 423 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 28323.787234
The remainder is 18 after subtracting 1692 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
423 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 28323.787234
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
If we divide 1800 by 423, we get 4 and a remainder of 108.
The next digit of our result is 4. 
Result so far: 28323.78723404
If we take 1692 away from 1800, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 28323.78723404 with a remainder of 1.08e-07.
