We divide 13647383 by 420
The aim is to understand the frequency of 420 in 13647383.

Going ahead to step 1:
The number 420 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 420

On to step 2:
The number 420 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 420

Let's proceed to step 3:
When dividing 136 by 420, we get 0 with a remainder of 136.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 136 to get 136.
Grab the next digit (4) from the dividend, add it to 136, then carry on: 1364 / 420

Moving on to step 4:
The number 420 fits into 1364 3 times, leaving a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1260 from 1364 and we're left with 104.
Take the next digit (7) from the dividend and append it to 104, then repeat: 1047 / 420

On to step 5:
420 goes into 1047 2 times with a remainder of 207.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 840 from 1047, we get 207.
Fetch the next digit (3) from the dividend, attach it to 207 and continue: 2073 / 420

Moving on to step 6:
2073 divided by 420 is 4 with a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 324.0
If we take 1680 away from 2073, we end up with 393.
Grab the next digit (8) from the dividend, add it to 393, then carry on: 3938 / 420

Moving on to step 7:
420 goes into 3938 9 times with a remainder of 158.
The next digit of our result is 9. 
Result so far: 3249.0
Subtracting 3780 from 3938 leaves us with 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 420

Moving on to step 8:
The number 420 fits into 1583 3 times, leaving a remainder of 323.
Record the quotient 3 as the next digit in the result. 
Result so far: 32493.0
If we take 1260 away from 1583, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 9:
420 goes into 3230 7 times with a remainder of 290.
Write down 7 as next digit of the result. 
Result so far: 32493.7
If we subtract 2940 from 3230, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
When dividing 2900 by 420, we get 6 with a remainder of 380.
Write down 6 as next digit of the result. 
Result so far: 32493.76
The remainder is 380 after subtracting 2520 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 420, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 32493.769
The remainder is 20 after subtracting 3780 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 420 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 32493.769
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
420 goes into 2000 4 times with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 32493.76904
Subtract 1680 from 2000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
3200 divided by 420 is 7 with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 32493.769047
If we take 2940 away from 3200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
2600 divided by 420 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 32493.7690476
Subtracting 2520 from 2600 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
800 divided by 420 is 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 32493.76904761
If we take 420 away from 800, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

After the division, we end up with 32493.76904761 and a remainder of 3.8e-07.
