420302 ÷ 54 
We want to figure out the number of times 420302 can be divided by 54.

Moving on to step 1:
54 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 54

Moving on to step 2:
When dividing 42 by 54, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 54

Going ahead to step 3:
When dividing 420 by 54, we get 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 42 after subtracting 378 from 420.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 54

Moving on to step 4:
The number 54 fits into 423 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 378 from 423, we get 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 54

Advancing to step 5:
450 divided by 54 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 778.0
If we subtract 432 from 450, we get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 54

Advancing to step 6:
182 divided by 54 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 7783.0
Subtracting 162 from 182 leaves us with 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 7:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 7783.3
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7783.37
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 54, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7783.37
If we subtract 0 from 20, 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.

Step 10:
If we divide 200 by 54, we get 3 and a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 7783.3703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
54 goes into 380 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7783.37037
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
54 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7783.37037
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 54 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 7783.3703703
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
If we divide 380 by 54, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7783.37037037
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 7783.37037037, with a leftover of 2e-09.
