We're dividing 420109 by 73 
We want to divide 420109 by 73.

Going ahead to step 1:
73 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
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 73

On to step 2:
73 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 73

Step 3:
73 can be fit into 420 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 365 from 420, we get 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 73

Going ahead to step 4:
551 divided by 73 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 511 from 551 leaves us with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 73

Going ahead to step 5:
400 divided by 73 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 575.0
The remainder is 35 after subtracting 365 from 400.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 73

Advancing to step 6:
If we divide 359 by 73, we get 4 and a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 5754.0
If we subtract 292 from 359, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
73 can be fit into 670 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 5754.9
Subtracting 657 from 670 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 8:
If we divide 130 by 73, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 5754.91
If we subtract 73 from 130, we 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.

Step 9:
73 goes into 570 7 times with a remainder of 59.
The next digit of our result is 7. 
Result so far: 5754.917
Subtract 511 from 570 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
73 goes into 590 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 5754.9178
Subtracting 584 from 590 leaves us 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.

Step 11:
73 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5754.9178
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
600 divided by 73 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5754.917808
The remainder is 16 after subtracting 584 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
73 can be fit into 160 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 5754.9178082
The remainder is 14 after subtracting 146 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 73 fits into 140 1 times, leaving a remainder of 67.
The next digit of our result is 1. 
Result so far: 5754.91780821
The remainder is 67 after subtracting 73 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 5754.91780821 with a remainder of 6.7e-08.
