We look at the division of 420274 by 73 
Let's see how many times 73 fits into 420274.

Step 1:
If we divide 4 by 73, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 73

On to step 2:
When dividing 42 by 73, 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.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 73

Step 3:
73 can be fit into 420 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 365 from 420 leaves us with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 73

Advancing to step 4:
When dividing 552 by 73, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 511 from 552 leaves us with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 73

Advancing to step 5:
When dividing 417 by 73, we get 5 with a remainder of 52.
The next digit of our result is 5. 
Result so far: 575.0
Deduct 365 from 417 and we're left with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 73

Let's proceed to step 6:
If we divide 524 by 73, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 5757.0
Subtracting 511 from 524 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
73 can be fit into 130 1 times, resulting in a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 5757.1
Subtract 73 from 130 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
73 can be fit into 570 7 times, resulting in a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 5757.17
Deduct 511 from 570 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
When dividing 590 by 73, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 5757.178
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 73 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 5757.178
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 73, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5757.17808
Deduct 584 from 600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 73 fits into 160 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 5757.178082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 73, we get 1 and a remainder of 67.
The next digit of our result is 1. 
Result so far: 5757.1780821
Deduct 73 from 140 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
The number 73 fits into 670 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 5757.17808219
If we subtract 657 from 670, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 5757.17808219 and a remainder of 1.3e-08.
