39527247 ÷ 420 
The aim is to understand the frequency of 420 in 39527247.

Let's proceed to step 1:
The number 420 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 420

Going ahead to step 2:
If we divide 39 by 420, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 420

Step 3:
When dividing 395 by 420, we get 0 with a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 395 after subtracting 0 from 395.
Bring next digit (2) of the dividend behind the 395 and repeat the process: 3952 / 420

Step 4:
When dividing 3952 by 420, we get 9 with a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 3780 from 3952 to get 172.
Append the next digit (7) from the dividend to 172 and continue with: 1727 / 420

Going ahead to step 5:
When dividing 1727 by 420, we get 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 94.0
Subtract 1680 from 1727 to get 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 420

Step 6:
472 divided by 420 is 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 941.0
The remainder is 52 after subtracting 420 from 472.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 420

Going ahead to step 7:
If we divide 524 by 420, we get 1 and a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 9411.0
If we subtract 420 from 524, we get 104.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 420

Let's proceed to step 8:
1047 divided by 420 is 2 with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 94112.0
The remainder is 207 after subtracting 840 from 1047.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 9:
420 can be fit into 2070 4 times, resulting in a remainder of 390.
The next digit of our result is 4. 
Result so far: 94112.4
If we take 1680 away from 2070, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
If we divide 3900 by 420, we get 9 and a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 94112.49
Subtracting 3780 from 3900 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 420 is 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 94112.492
Deduct 840 from 1200 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
420 can be fit into 3600 8 times, resulting in a remainder of 240.
The next digit of our result is 8. 
Result so far: 94112.4928
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
420 goes into 2400 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 94112.49285
The remainder is 300 after subtracting 2100 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 94112.492857
Subtract 2940 from 3000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
When dividing 600 by 420, we get 1 with a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 94112.4928571
Deduct 420 from 600 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
When dividing 1800 by 420, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 94112.49285714
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 94112.49285714 with a balance of 1.2e-07.
