We're dividing 20774327 by 420 
The aim is to understand the frequency of 420 in 20774327.

Going ahead to step 1:
If we divide 2 by 420, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 420

Moving on to step 2:
20 divided by 420 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 420

Advancing to step 3:
207 divided by 420 is 0 with a remainder of 207.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 207 to get 207.
Take the next digit (7) from the dividend and append it to 207, then repeat: 2077 / 420

Advancing to step 4:
2077 divided by 420 is 4 with a remainder of 397.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 397 after subtracting 1680 from 2077.
Bring next digit (4) of the dividend behind the 397 and repeat the process: 3974 / 420

On to step 5:
When dividing 3974 by 420, we get 9 with a remainder of 194.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we take 3780 away from 3974, we end up with 194.
Bring next digit (3) of the dividend behind the 194 and repeat the process: 1943 / 420

Advancing to step 6:
If we divide 1943 by 420, we get 4 and a remainder of 263.
Put 4 as the next digit of the answer. 
Result so far: 494.0
If we take 1680 away from 1943, we end up with 263.
Take the next digit (2) from the dividend and append it to 263, then repeat: 2632 / 420

Advancing to step 7:
If we divide 2632 by 420, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 4946.0
If we take 2520 away from 2632, we end up with 112.
Bring next digit (7) of the dividend behind the 112 and repeat the process: 1127 / 420

Step 8:
When dividing 1127 by 420, we get 2 with a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 49462.0
Deduct 840 from 1127 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
2870 divided by 420 is 6 with a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 49462.6
If we take 2520 away from 2870, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
420 can be fit into 3500 8 times, resulting in a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 49462.68
If we take 3360 away from 3500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 420 fits into 1400 3 times, leaving a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 49462.683
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
If we divide 1400 by 420, we get 3 and a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 49462.6833
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 49462.6833 with a balance of 0.0014.
