Let's divide 10423656 by 420
The aim is to understand the frequency of 420 in 10423656.

Step 1:
420 goes into 1 0 times with 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.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 420

Going ahead to step 2:
420 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 420

On to step 3:
420 can be fit into 104 0 times, resulting in a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Fetch the next digit (2) from the dividend, attach it to 104 and continue: 1042 / 420

Moving on to step 4:
420 goes into 1042 2 times with a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 840 from 1042, we get 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 420

Advancing to step 5:
When dividing 2023 by 420, we get 4 with a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 1680 from 2023, we get 343.
Include the next digit (6) from the dividend after 343, then repeat: 3436 / 420

Step 6:
3436 divided by 420 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 248.0
Deduct 3360 from 3436 and we're left with 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 420

Advancing to step 7:
765 divided by 420 is 1 with a remainder of 345.
The next digit of our result is 1. 
Result so far: 2481.0
Subtracting 420 from 765 leaves us with 345.
Fetch the next digit (6) from the dividend, attach it to 345 and continue: 3456 / 420

Let's proceed to step 8:
420 can be fit into 3456 8 times, resulting in a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 24818.0
Deduct 3360 from 3456 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
If we divide 960 by 420, we get 2 and a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 24818.2
If we take 840 away from 960, we end up 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.

Moving on to step 10:
1200 divided by 420 is 2 with a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 24818.22
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 24818.22 with a balance of 0.36.
