Let's divide 14907477 by 420
We want to figure out the number of times 14907477 can be divided by 420.

Step 1:
1 divided by 420 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 420

Moving on to step 2:
When dividing 14 by 420, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 420

Step 3:
420 can be fit into 149 0 times, resulting in a remainder of 149.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 149, we get 149.
Include the next digit (0) from the dividend after 149, then repeat: 1490 / 420

Advancing to step 4:
The number 420 fits into 1490 3 times, leaving a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1260 from 1490 leaves us with 230.
Take the next digit (7) from the dividend and append it to 230, then repeat: 2307 / 420

On to step 5:
420 can be fit into 2307 5 times, resulting in a remainder of 207.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 2100 away from 2307, we end up with 207.
Bring next digit (4) of the dividend behind the 207 and repeat the process: 2074 / 420

Moving on to step 6:
If we divide 2074 by 420, we get 4 and a remainder of 394.
The next digit of our result is 4. 
Result so far: 354.0
If we take 1680 away from 2074, we end up with 394.
Include the next digit (7) from the dividend after 394, then repeat: 3947 / 420

Step 7:
3947 divided by 420 is 9 with a remainder of 167.
The next digit of our result is 9. 
Result so far: 3549.0
If we take 3780 away from 3947, we end up with 167.
Bring next digit (7) of the dividend behind the 167 and repeat the process: 1677 / 420

Let's proceed to step 8:
If we divide 1677 by 420, we get 3 and a remainder of 417.
The next digit of our result is 3. 
Result so far: 35493.0
If we take 1260 away from 1677, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 9:
420 can be fit into 4170 9 times, resulting in a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 35493.9
Deduct 3780 from 4170 and we're left 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.

Let's proceed to step 10:
If we divide 3900 by 420, we get 9 and a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 35493.99
If we subtract 3780 from 3900, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 35493.99 with a remaining 0.12.
