40892384 ÷ 420 
The aim is to understand the frequency of 420 in 40892384.

Moving on to step 1:
4 divided by 420 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 420

Step 2:
The number 420 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 420

Let's proceed to step 3:
420 can be fit into 408 0 times, resulting in a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 408, we end up with 408.
Take the next digit (9) from the dividend and append it to 408, then repeat: 4089 / 420

Let's proceed to step 4:
4089 divided by 420 is 9 with a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 3780 from 4089 and we're left with 309.
Append the next digit (2) from the dividend to 309 and continue with: 3092 / 420

Advancing to step 5:
420 goes into 3092 7 times with a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 152 after subtracting 2940 from 3092.
Bring next digit (3) of the dividend behind the 152 and repeat the process: 1523 / 420

On to step 6:
420 goes into 1523 3 times with a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 973.0
Subtract 1260 from 1523 to get 263.
Grab the next digit (8) from the dividend, add it to 263, then carry on: 2638 / 420

Step 7:
If we divide 2638 by 420, we get 6 and a remainder of 118.
Put 6 as the next digit of the answer. 
Result so far: 9736.0
Subtracting 2520 from 2638 leaves us with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 420

Advancing to step 8:
1184 divided by 420 is 2 with a remainder of 344.
The next digit of our result is 2. 
Result so far: 97362.0
If we take 840 away from 1184, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 9:
3440 divided by 420 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 97362.8
If we take 3360 away from 3440, we end up 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.

On to step 10:
800 divided by 420 is 1 with a remainder of 380.
The next digit of our result is 1. 
Result so far: 97362.81
Subtracting 420 from 800 leaves us 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.

Moving on to step 11:
If we divide 3800 by 420, we get 9 and a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 97362.819
If we subtract 3780 from 3800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
200 divided by 420 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 97362.819
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
When dividing 2000 by 420, we get 4 with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 97362.81904
If we take 1680 away from 2000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
The number 420 fits into 3200 7 times, leaving a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 97362.819047
If we subtract 2940 from 3200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 15:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 97362.8190476
If we subtract 2520 from 2600, we get 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.
Record the quotient 1 as the next digit in the result. 
Result so far: 97362.81904761
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 97362.81904761 with a remaining 3.8e-07.
